Sanctification is a work of the triune God, but is ascribed more particularly to the Holy Spirit in Scripture, Rom. 8:11; 15:16; I Pet. 1:2. It is particularly important in our day, with its emphasis on the necessity of approaching the study of theology anthropologically and its one-sided call to service in the kingdom of God, to stress the fact that God, and not man, is the author of sanctification. Especially in view of the Activism that is such a characteristic feature of American religious life, and which glorifies the work of man rather than the grace of God, it is necessary to stress the fact over and over again that sanctification is the fruit of justification, that the former is simply impossible without the latter, and that both are the fruits of the grace of God in the redemption of sinners. Though man is privileged to cooperate with the Spirit of God, he can do this only in virtue of the strength which the Spirit imparts to him from day to day. The spiritual development of man is not a human achievement, but a work of divine grace. Man deserves no credit whatsoever for that which he contributes to it instrumentally. In so far as sanctification takes place in the subconscious life, it is effected by the immediate operation of the Holy Spirit. But as a work in the conscious life of believers it is wrought by several means, which the Holy Spirit employs. 

In opposition to the Church of Rome it should be maintained that the principal means used by the Holy Spirit is the Word of God. The truth in itself certainly has no adequate efficiency to sanctify the believer, yet it is naturally adapted to be the means of sanctification as employed by the Holy Spirit. Scripture presents all the objective conditions for holy exercises and acts. It serves to excite spiritual activity by presenting motives and inducements, and gives direction to it by prohibitions, exhortations, and examples, I Pet. 1:22; 2:2; II Pet. 1:4. 

These are the means par excellence according to the Church of Rome. Protestants' regard them as subordinate to the Word of God, and sometimes even speak of them as the "visible Word." They symbolize and seal to us the same truths that are verbally expressed in the Word of God, and may be regarded as an acted word, containing a lively representation of the truth, which the Holy Spirit makes the occasion for holy exercise They are not only subordinate to the Word of God, but cannot exist without it, and are therefore always accompanied by it, ROM 6:3; I Cor. 12:13; Tit. 3:5; I Pet. 3:21. 

God's providences, both favorable and adverse, are often powerful means of sanctification. In connection with the operation of the Holy Spirit through the Word, they work on our natural affections and thus frequently deepen the impression of religious truth and force it home. It should be borne in mind that the light of God's revelation is necessary for the interpretation of His providential guidance's, Ps. 119:71; ROM 2:4; Heb. 12:10.

l. As appears from the immediately preceding, sanctification is a work of which God and not man is the author. Only the advocates of the so-called free will can claim that it is a work of man. Nevertheless, it divers from regeneration in that man can, and is in duty bound to, strive for ever-increasing sanctification by using the means which God has placed at his disposal. This is clearly taught in Scripture, II Cor. 7:1; Col. 3:5-14; I Pet. 1:22. Consistent Antinomians lose sight of this important truth, and feel no need of carefully avoiding sin, since this affects only the old man which is condemned to death, and not the new man which is holy with the holiness of Christ.  

2. Sanctification takes place partly in the subconscious life, and as such is an immediate operation of the Holy Spirit; but also partly in the conscious life, and then depends on the use of certain means, such as the constant exercise of faith, the study of God's Word, prayer, and association with other believers. 

3. Sanctification is usually a lengthy process and never reaches perfection in this life. At the same time there may be cases in which it is completed in a very short time or even in a moment, as, for instance, in cases in which regeneration and conversion are immediately followed by temporal death. If we may proceed on the assumption that the believer's sanctification is perfect immediately after death -- and Scripture seems to teach this as far as the soul is concerned --, then in such cases the sanctification of the soul must be completed almost at once. 

4. The sanctification of the believer must, it would seem, be completed either at the very moment of death, or immediately after death, as far as the soul is concerned, and at the resurrection in so far as it pertains to the body. This would seem to follow from that fact that, on the one hand, the Bible teaches that in the present life no one can claim freedom from sin, I Kings 8:46; Prov. 20:9; ROM 3:10,12; Jas. 3:2; I John 1:8; and that, on the other hand, those who have gone before are entirely sanctified. It speaks of them as "the spirits of just men made perfect," Heb. 12:23, and as "without blemish," Rev. 14:5.

Moreover, we are told that in the heavenly city of God there shall in no wise enter "anything unclean or he that maketh an abomination and a lie," Rev. 21:27; and that Christ at His coming will "fashion anew the body of our humiliation, that it may be conformed to the body of His glory," Phil. 3:21.

Sanctification and good works are most intimately related. Just as the old life expresses itself in works of evil, so the new life, that originates in regeneration and is promoted and strengthened in sanctification, naturally manifests itself in good works, and as such come into consideration here. These may be called the fruits of sanctification, and as such come into consideration here. 

a. Good works in the specifically theological sense. When we speak of good works in connection with sanctification, we do not refer to works that are perfect, that answer perfectly to the requirements of the divine moral law, and that are of such inherent worth as to entitle one to the reward of eternal life under the conditions of the covenant of works. We do mean, however, works that are essentially different in moral quality from the actions of the unregenerate, and that are the expressions of a new and holy nature as the principle from which they spring. These are works which God not only approves, but in a certain sense also rewards. The following are the characteristics of works that are spiritually good: (1) They are the fruits of a regenerate heart, since without this no one can have the disposition (to obey God) and the motive (to glorify God) that is required, Matt. 12:33; 7:17,18. (2) They are not only in external conformity with the law of God, but are also done in conscious obedience to the revealed will of God, that is, because they are required by God. They spring from the principle of love to God and from the desire to do His will, Deut. 6:2; I Sam. 15:22; Isa. 1:12; 29:13; Matt. 15:9. (3) Whatever their proximate aim may be, their final aim is not the welfare of man, but the glory of God, which is the highest conceivable aim of man´s life, I Cor. 10:31; ROM 12:1; Col. 3:17, 23. 

b. Good works in a more general sense. Though the term “good works” is generally used in theology in the strict sense just indicated, it remains true that the unregenerate can also perform works that may be called good in a superficial sense of the word. They often perform works that are in outward conformity with the law of God and may be called objectively good, in distinction from flagrant transgressions of the law. Such works answer to a proximate aim that meets with the approval of God. Moreover, in virtue of the remains of the image of God in the natural man and of the light of nature, man may be guided in his relation to other men by motives which are laudable and in so far bear the stamp of God´s approval. Those good works, however, cannot be regarded as fruits of the corrupt heart of man. They find their explanation only in the common grace of God. Furthermore, we should bear in mind that, though these works can be called good in a certain sense and are so called in the Bible, Luke 6:33, they are yet essentially defective. The deeds of the unregenerate are divorced from the spiritual root of love to God.  They represent no inner obedience to the law of God and no subjection to the will of the sovereign Ruler of heaven and earth. They have no spiritual aim, since they are not performed for the purpose of glorifying God, but only bear on the relations of the natural life. The real quality of the act is, of course, determined by the quality of its final aim. The ability of the unregenerate to perform good works in some sense of the word has often been denied. Barth goes one step further when he goes to the extreme of denying that believers can do good works, and asserts that all their works are sins. 

Even from the earliest ages of the Christian Church there was a tendency to ascribe a certain merit to-good works, but the doctrine of merit was really developed in the Middle Ages.  At the time of the Reformation it was very prominent in Roman Catholic theology and was pushed to ridiculous extremes in practical life. The Reformers at once joined issue with the Church of Rome on this point. 

a. The position of Rome on the point in question. The Roman Catholic Church distinguishes between a meritum de condigno, which represents inherent dignity and worth, and a meritum de congruo, which is a sort of quasi-merit, something fit to be rewarded. The former attaches only to works done after regeneration by the aid of divine grace, and is a merit which intrinsically deserves the reward it receives from the hand of God. The latter attaches to those dispositions or works which a man may develop or do before regeneration, in virtue of a mere prevenient grace, and is a merit which makes it congruous or fitting for God to reward the agent by infusing grace into his heart. Since the decisions of the Council of Trent are rather dubious on this point, there is some uncertainty, however, as to the exact position of the Church. The general idea seems to be that the ability to perform good works in the strict sense of the word springs from grace infused into the sinner´s heart for the sake of Christ; and that afterwards these good works merit, that is, give man a just claim to, salvation and glory. The Church goes even farther than that, and teaches that believers can perform works of supererogation, can do more than is necessary for their own salvation and can thus lay by a store of good works, which may accrue to the benefit of others. 

b. The Scriptural position on this point. Scripture clearly teaches that the good works of believers´ are not meritorious in the proper sense of the word.  We should bear in mind, however, that the word “merit” is employed in a twofold sense, the one strict and proper, and the other loose. Strictly speaking, a meritorious work is one to which, on account of its intrinsic value and dignity, the reward is justly due from commutative justice. Loosely speaking, however, a work that is deserving of approval and to which a reward is somehow attached (by promise, agreement, or otherwise) is also sometimes called meritorious. Such works are praiseworthy and are rewarded by God. But, however this may be, they are surely not meritorious in the strict sense of the word. They do not, by their own intrinsic moral value, make God a debtor to him who performs them. In strict justice the good works of believers merit nothing. Some of the most conclusive passages of Scripture to prove the point under consideration are the following: Luke 17:9, 10; ROM 5:15-18; 6:23; Eph. 2:8-10; II Tim. 1:9; Tit. 3:5. These passages clearly show that believers do not receive the inheritance of salvation because it is due to them in virtue of their good works, but only as a free gift of God. It stands to reason also that such works cannot be meritorious, for: (1) Believers owe their whole life to God and therefore cannot merit anything by giving God simply what is His due, Luke 17:9,10. (2) They cannot perform good works in their own strength, but only in the strength which God imparts to them from day to day; and in view of that fact they cannot expect the credit for these works, I Cor. 15:10; Phil. 2:13. (3) Even the best works of believers remain imperfect in this life; and all good works together represent only a partial obedience, while the law demands perfect obedience and can be satisfied with nothing less, Isa. 64:6; Jas. 3:2. (4) Moreover, the good works of believers are out of all proportion to the eternal reward of glory. A temporal and imperfect obedience can never merit an eternal and perfect reward. 

There can be no doubt about the necessity of good works properly understood. They cannot be regarded as necessary to merit salvation, nor as a means to retain a hold on salvation, nor even as the only way along which to proceed to eternal glory, for children enter salvation without having done any good works. The Bible does not teach that no one can be saved apart from good works. At the same time good works necessarily follow from the union of believers with Christ. “He that abideth in me and I in him, the same beareth much fruit,” John 15:5. They are also necessary as required by God, ROM 7:4; 8:12.13; Gal. 6:2, as the fruits of faith, Jas.  2:14, 17, 20-22, as expressions of gratitude. I Cor. 6:20, unto the assurance, of faith, II Peter 1:5-10, and to the glory of God, John 15:8; I Cor. 10:31. The necessity of good works must be maintained over against the Antinomians, who claim that, since Christ not only bore the penalty of sin, but also met the positive demands of the law, the believer is free from the obligation to observe it, an error that is still with us today in some of the forms of dispensationalism.  This is a thoroughly false position, for it is only the law as a system of penalty and as a method of salvation that is abolished in the death of Christ. The law as the standard of our moral life is a transcript of the holiness of God and is therefore of permanent validity also for the believer, though his attitude to the law has undergone a radical change. He has received the Spirit of God, which is the Spirit of obedience, so that, without any constraint, he willingly obeys the law. Strong sums it up well, when he says: Christ frees us “(1) from the law as a system of curse and penalty; this He does by bearing the curse and penalty Himself... ; (2) from the law with its claims as a method of salvation; this He does by making His obedience and merits ours... ; (3) from the law as an outward and foreign compulsion; this He does by giving us the spirit of obedience and Sonship, by which the law is progressively realized within.” [1]

The Old Testament word for ‘to sanctify´ is qadash, a verb that is used in the niphal, piet, hiphil, and hithpa´el species. The corresponding noun is qodesh, while the adjective is qadosh. The verbal forms are derived from the nominal and adjectival forms. The original meaning of these words is uncertain. Some are of the opinion that the word qadash is related to chadash, meaning ‘to shine.´ This would be in harmony with the qualitative aspect of the Biblical idea of holiness, namely, that of purity. Others, with a greater degree of probability, derive the word from the root qad, meaning ‘to cut.´ This would make the idea of separation the original idea. The word would then point to aloofness, separateness, or majesty. Though this meaning of the words ‘sanctification´ and ‘holiness´ may seem unusual to us, it is in all probability the fundamental idea expressed by them. Says Girdlestone: “The terms ‘sanctification´ and ‘holiness´ are now used so frequently to represent moral and spiritual qualities, that they hardly convey to the reader the idea of position or relationship as existing between God and some person or thing consecrated to Him; yet this appears to be the real meaning of the word.” [1] Similarly, Cremer-Koegel calls attention to the fact that the idea of separation is fundamental to that of holiness. “Heiligkeit ist ein verhaeltnisbegriff.” At the same time it is admitted that the two ideas of holiness and separation do not merge, are not absorbed in each other, but that the former in a measure serves to qualify the latter. [2]

 a. The verb hagiazo and its various meanings. The verb hagiazo is a derivative of hagios, which like the Hebrew qadosh expresses primarily the idea of separation. It is used in several different senses, however, in the New Testament. We may distinguish the following: (1) It is used in a mental sense of persons or things, Matt. 6:9; Luke 11:2; I Pet. 3:15. In such cases it means “to regard an object as holy,” “to ascribe holiness to it,” or “to acknowledge its holiness by word or deed.” (2) It is also employed occasionally in a ritual sense, that is, in the sense of “separating from ordinary for sacred purposes,” or of “setting aside for a certain office,” Matt. 23:17, 19; John 10:36; II Tim. 2:21. (3) Again it is used to denote that operation of God by which He, especially through His Spirit, works in man the subjective quality of holiness, John 17:17; Acts 20:32; 26:18; I Cor. 1:2; I Thess. 5:23. (4) Finally, in the Epistle to the Hebrews it seems to be used in an expiatory sense, and also in the related sense of the Pauline dikaio-o, Heb. 9:13; 10:10, 29; 13:12. [3] 

b. The adjectives expressive of the idea of holiness. (1) Hieros. The word that is used least and that is also the least expressive, is the word hieros. It is found only in I Cor. 9:13; II Tim. 3:15, and then not of persons but of things. It does not express moral excellence, but is expressive of the inviolable character of the thing referred to, which springs from the relation in which it stands to God. It is best translated by the English word "sacred." (2) Hosios. The word hosios is of more frequent occurrence. It is found in Acts 2:27; 13:34,35; I Tim. 2:8; Tit. 1:8; Heb. 7:26; Rev. 15:4; 16:5, and is applied not only to things, but also to God and to Christ. It describes a person or thing as free from defilement or wickedness, or more actively (of persons) as religiously fulfilling every moral obligation. (3) Hagnos. The word hagnos occurs in II Cor. 7:11; 11:2; Phil. 4:8; I Tim. 5:22; Jas. 3:17; I Pet. 3:2; I John 3:3. The fundamental idea of the word seems to be that of freedom from impurity and defilement in an ethical sense. (4) Hagios. The really characteristic word of the New Testament, however, is hagios. Its primary meaning is that of separation in consecration and devotion to the service of God. With this is connected the idea that what is set aside from the world for God, should also separate itself from the world's defilement and share in God's purity. This explains the fact that hagios speedily acquired an ethical signification. The word does not always have the same meaning in the New Testament. (a) It is used to designate an external official relation, a being set aside from ordinary purposes for the service of God, as for instance, when we read of "holy prophets," Luke 1:70, "holy apostles," Eph. 3:5, and "holy men of God" II Pet. 1:21. (b) More often, however, it is employed in an ethical sense to describe the quality that is necessary to stand in close relation to God and to serve Him acceptably, Eph. 1:4; 5:27; Col. 1:22: I Pet. 1:15,16. It should be borne in mind that in treating of sanctification we use the word primarily in the latter sense. When we speak of holiness in connection with sanctification, we have in mind both an external relation and an inner subjective quality. c. The nouns denoting sanctification and holiness. The New Testament word for sanctification is hagiasmos. It occurs ten times, namely, in ROM 6:19, 22; I Cor. 1:30; I Thess. 4:3,4,7; II Thess. 2:13; I Tim. 2:15; Heb. 12:14; I Pet. I:2. While it denotes ethical purification, it includes the idea of separation, namely, "the separation of the spirit from all that is impure and polluting, and a renunciation of the sins towards which the desires of the flesh and of the mind lead us." While hagiasmos denotes the work of sanctification, there are two other words that describe the result of the process, namely, hagiotes and hagiosune. The former is found in I Cor. 1:30 and Heb. 12:10; and the latter in ROM 1:4; II Cor. 7:1, and I Thess. 3:13. These passages show that the quality of holiness or freedom from pollution and impurity is essential to God, was exhibited by Jesus Christ, and is imparted to the Christian.

In the historical unfolding of the doctrine of sanctification, the Church concerned itself primarily with three problems: (a) the relation of the grace of God in sanctification to faith; (b) the relation of sanctification to justification; and (c) the degree of sanctification in this present life. The writings of the early Church Fathers contain very little respecting the doctrine of sanctification. A strain of moralism is quite apparent in that man was taught to depend for salvation on faith and good works. Sins committed before baptism were washed away in baptism, but for those after baptism man must provide by penance and good works. He must lead a life of virtue and thus merit the approval of the Lord. "Such dualism," says Scott in his The Nicene Theology,[1] "left the domain of sanctification only indirectly related to the redemption of Christ; and this was the field in which grew up, naturally, defective conceptions of sin, legalism, Sacramentarianism, priestcraft, and all the excesses of monkish devotion." Asceticism came to be regarded as of the greatest importance. There was also a tendency to confound justification and sanctification. Augustine was the first one to develop rather definite ideas of sanctification, and his views had a determining influence on the Church of the Middle Ages. He did not clearly distinguish between justification and sanctification, but conceived of the latter as included in the former. Since he believed in the total corruption of human nature by the fall, he thought of sanctification as a new supernatural impartation of divine life, a new infused energy, operating exclusively within the confines of the Church and through the sacraments. While he did not lose sight of the importance of personal love to Christ as a constituent element in sanctification, he manifested a tendency to take a metaphysical view of the grace of God in sanctification, -- to regard it as a deposit of God in man. He did not sufficiently stress the necessity of a constant preoccupation of faith with the redeeming Christ, as the most important factor in the transformation of the Christian's life. The tendencies apparent in the teachings of Augustine came to fruitage in the theology of the Middle Ages, which is found in its most developed form in the writings of Thomas Aquinas. Justification and sanctification are not clearly distinguished, but the former is made to include the infusion of divine grace, as something substantial, into the human soul. This grace is a sort of donum superadditum, by which the soul is lifted to a new level or a higher order of being, and is enabled to achieve its heavenly destiny of knowing, possessing, and enjoying God. The grace is derived from the inexhaustible treasury of the merits of Christ and is imparted to believers by the sacraments. Looked at from the divine point of view, this sanctifying grace within the soul secures the remission of original sin, imparts a permanent habit of inherent righteousness, and carries within itself the potency of further development, and even of perfection. Out of it the new life develops with all its virtues. Its good, work can be neutralized or destroyed by mortal sins; but the guilt contracted after baptism can be removed by the Eucharist in the case of venial sins, and by the sacrament of penance in the case of mortal sins. Considered from the human point of view, the supernatural works of faith working through love have merit before God, and secure an increase of grace. Such works are impossible, however, without the continuous operation of the grace of God. The result of the whole process was known as justification rather than as sanctification; it consisted in making man just before God. These ideas are embodied in the Canons and Decrees of the Council of Trent.

The Reformers in speaking of sanctification emphasized the antithesis of sin and redemption rather than that of nature and supernature. They made a clear distinction between justification and sanctification, regarding the former as a legal act of divine grace, affecting the judicial status of man, and the latter, as a moral or re-creative work, changing the inner nature of man. But while they made a careful distinction between the two, they also stressed their inseparable connection. While deeply convinced that man is justified by faith alone, they also understood that the faith which justifies is not alone. Justification is at once followed by sanctification, since God sends out the Spirit of His Son into the hearts of His own as soon as they are justified, and that Spirit is the Spirit of sanctification. They did not regard the grace of sanctification as a supernatural essence infused in man through the sacraments, but as a supernatural and gracious work of the Holy Spirit, primarily through the Word and secondarily through the sacraments, by which He delivers us more and more from the power of sin and enables us to do good works. Though in no way confounding justification and sanctification, they felt the necessity of preserving the closest possible connection between the former, in which the free and forgiving grace of God is strongly emphasized, and the latter, which calls for the cooperation of man, in order to avoid the danger of work-righteousness. In Pietism and Methodism great emphasis was placed on constant fellowship with Christ as the great means of sanctification. By exalting sanctification at the expense of justification, they did not always avoid the danger of self-righteousness. Wesley did not merely distinguish justification and sanctification, but virtually separated them, and spoke of entire sanctification as a second gift of grace, following the first, of justification by faith, after a shorter or longer period. While he also spoke of sanctification as a process, he yet held that the believer should pray and look for full sanctification at once by a separate act of God. Under the influence of Rationalism and of the moralism of Kant sanctification ceased to be regarded as a supernatural work of the Holy Spirit in the renewal of sinners, and was brought down to the level of a mere moral improvement by the natural powers of man. For Schleiermacher it was merely the progressive domination of the God consciousness within us over the merely sentient and ever morally defective world consciousness. And for Ritschl it was the moral perfection of the Christian life to which we attain by fulfilling our vocation as members of the Kingdom of God. In a great deal of modern liberal theology sanctification consists only in the ever-increasing redemption of man's lower self by the domination of his higher self. Redemption by character is one of the slogans of the present day, and the term "sanctification" has come to stand for mere moral improvement.

 Some have the mistaken notion that sanctification consists merely in the drawing out of the new life, implanted in the soul by regeneration, in a persuasive way by presenting motives to the will. But this is not true. It consists fundamentally and primarily in a divine operation in the soul, whereby the holy disposition born in regeneration is strengthened and its holy exercises are increased. It is essentially a work of God, though in so far as He employs means, man can and is expected to cooperate by the proper use of these means. Scripture clearly exhibits the supernatural character of sanctification in several ways. It describes it as a work of God, I Thess. 5:23; Heb. 18:20, 21, as a fruit of the union of life with Jesus Christ, John 15:4; Gal. 2:20; 4:19, as a work that is wrought in man from within and which for that very reason cannot be a work of man, Eph. 3:16; Col. 1:11, and speaks of its manifestation in Christian virtues as the work of the Spirit, Gal. 5:22. It should never be represented as a merely natural process in the spiritual development of man, nor brought down to the level of a mere human achievement, as is done in a great deal of modern liberal theology. 

The two parts of sanctification are represented in Scripture as: 

a. The mortification of the old man, the body of sin. This Scriptural term denotes that act of God whereby the pollution and corruption of human nature that results from sin is gradually removed. It is often represented in the Bible as the crucifying of the old man, and is thus connected with the death of Christ on the cross. The old man is human nature in so far as it is controlled by sin, ROM 6:6; Gal. 5:24. In the context of the passage of Galatians Paul contrasts the works of the flesh and the works of the Spirit, and then says: "And they who are of Christ Jesus have crucified the flesh with the passions and the lusts thereof." This means that in their case the Spirit has gained predominance.

b. The quickening of the new man, created in Christ Jesus unto good works. While the former part of sanctification is negative in character, this is positive. It is that act of God whereby the holy disposition of the soul is strengthened, holy exercises are increased, and thus a new course of life engendered and promoted. The old structure of sin is gradually torn down, and a new structure of God is reared in its stead. These two parts of sanctification are not successive but contemporaneous. Thank God, the gradual erection of the new building need not wait until the old one is completely demolished. If it had to wait for that, it could never begin in this life. With the gradual dissolution of the old the new makes its appearance. It is like the airing of a house filled with pestiferous odors. As the old air is drawn out, the new rushes in. This positive side of sanctification is often called "a being raised together with Christ," ROM 6:4, 5; Col. 2:12; 3:1, 2. The new life to which it leads is called "a life unto God," ROM 6:11; Gal. 2:19. 

This follows from the nature of the case, because sanctification takes place in the inner life of man, in the heart, and this cannot be changed without changing the whole organism of man. If the inner man is changed, there is bound to be change also in the periphery of life. Moreover, Scripture clearly and explicitly teaches that it affects both body and soul, I Thess. 5:23; II Cor. 5:17; ROM 6:12; I Cor. 6:15,20. The body comes into consideration here as the organ or instrument of the sinful soul, through which the sinful inclinations and habits and passions express themselves. The sanctification of the body takes place especially in the crisis of death and in the resurrection of the dead. Finally, it also appears from Scripture that sanctification affects all the powers or faculties of the soul, the understanding, Jer. 31:34; John 6:45; -- the will, Ezek. 36:25-27; Phil. 2:13; -- the passions, Gal. 5:24; -- and the conscience, Tit. 1:15; Heb. 9:14. 

When it is said that man takes part in the work of sanctification, this does not mean that man is an independent agent in the work, so as to make it partly the work of God and partly the work of man; but merely, that God effects the work in part through the instrumentality of man as a rational being, by requiring of him prayerful and intelligent cooperation with the Spirit. That man must cooperate with the Spirit of God follows:  (a) from the repeated warnings against evils and temptations, which clearly imply that man must be active in avoiding the pitfalls of life, ROM 12:9,16,17; I Cor. 6:9,10; Gal. 5:16-23; and (b) from the constant exhortations to holy living. These imply that the believer must be diligent in the employment of the means at his command for the moral and spiritual improvement of his life, Micah 6:8; John 15:2,8,16; ROM 8:12,13; 12:1,2,17; Gal. 6:7,8,15.

When we speak of sanctification as being imperfect in this life, we do not mean to say that it is imperfect in parts, as if only a part of the holy man that originates in regeneration were affected. It is the whole, but yet undeveloped new man, that must grow into full stature. A newborn child is, barring exceptions, perfect in parts, but not yet in the degree of development for which it is intended. Just so the new man is perfect in parts, but remains in the present life imperfect in the degree of spiritual development. Believers must contend with sin as long as they live, I Kings 8:46; Prov. 20:9; Eccl. 7:20; Jas. 3:2; I John 1:8. 

a. The doctrine of perfectionism. Speaking generally, this doctrine is to the effect that religious perfection is attainable in the present life. It is taught in various forms by Pelagians, Roman Catholics or Semipelagians, Arminians, Wesleyans, such mystical sects as the Labadists, the Quietists, the Quakers, and others, some of the Oberlin theologians, such as Mahan and Finney, and Ritschl.  These all agree in maintaining that it is possible for believers in this life to attain to a state in which they comply with the requirements of the law under which they now live, or under that law as it was adjusted to their present ability and needs, and, consequently, to be free from sin. They differ, however: 

(1) In their view of sin, the Pelagians, in distinction from all the rest, denying the inherent corruption of man. They all agree, however, in externalizing sin. 

(2) In their conception of the law which believers are now obliged to fulfill, the Arminians, including the Wesleyans, differing from all the rest in holding that this is not the original moral law, but the gospel requirements or the new law of faith and evangelical obedience. The Roman Catholics and the Oberlin theologians maintain that it is the original law, but admit that the demands of this law are adjusted to man´s deteriorated powers and to his present ability. And Ritschl discards the whole idea that man is subject to an externally imposed law. He defends the autonomy of moral conduct, and holds that we are under no law but such as is evolved out of our own moral disposition in the course of activities for the fulfillment of our vocation.  

(3) In their idea of the sinner´s dependence on the renewing grace of God for the ability to fulfill the law. All, except the Pelagians, admit that he is in some sense dependent on divine grace, in order to the attainment of perfection. 

It is very significant that all the leading perfectionist theories (with the sole exception of the Pelagian, which denies the inherent corruption of man) deem it necessary to lower the standard of perfection and do not hold man responsible for a great deal that is undoubtedly demanded by the original moral law. And it is equally significant that they feel the necessity of externalizing the idea of sin, when they claim that only conscious wrongdoing can be so considered, and refuse to recognize as sin a great deal that is represented as such in Scripture. 

b. Scriptural proofs adduced for the doctrine of perfectionism. 

(1) The Bible commands believers to be holy and even to be perfect, I Pet. 1:16; Matt. 5:48; Jas. 1:4, and urges them to follow the example of Christ who did no sin, I Pet. 2:21 f. Such commands would be unreasonable, if it were not possible to reach sinless perfection. But the Scriptural demand to be holy and perfect holds for the unregenerate as well as for the regenerate, since the law of God demands holiness from the start and has never been revoked.  If the command implies that they to whom it comes can live up to the requirement, this must be true of every man. However, only those who teach perfectionism in the Pelagian sense can hold that view. The measure of our ability cannot be inferred from the Scriptural commandments. 

(2) Holiness and perfection are often ascribed to believers in Scripture, Song of Sol. 4:7; I Cor. 2:6; II Cor. 5:17; Eph. 5:27; Heb. 5:14; Phil. 4:13; Col. 2:10. When the Bible speaks of believers as holy and perfect, however, this does not necessarily mean that they are without sin, since both words are often used in a different sense, not only in common parlance, but also in the Bible. Persons set aside for the special service of God are called holy in the Bible, irrespective of their moral condition and life. Believers can be and are called holy, because they are objectively holy in Christ, or because they are in principle subjectively sanctified by the Spirit of God. Paul in his Epistles invariably addresses his readers as saints, that is “holy ones,” and then proceeds in several cases to take them to task for their sins. And when believers are described as perfect, this means in some cases merely that they are full grown, I Cor. 2:6; Heb. 5:14, and in others that they are fully equipped for their task, II Tim. 3:17. All this certainly does not give countenance to the theory of sin less perfection. 

(3) There are, it is said, Biblical examples of saints who led perfect lives, such as Noah, Job, and Asa, Gen. 6:9; Job 1:1; I Kings 15:14. But, surely, such examples as these do not prove the point for the simple reason that they are no examples of sinless perfection. Even the most notable saints of the Bible are pictured as men who had their failings and who sinned, in some cases very grievously. This is true of Noah, Moses, Job, Abraham, and all the others. It is true that this does not necessarily prove that their lives remained sinful as long as they lived on earth, but it is a striking fact that we are not introduced to a single one who was without sin. The question of Solomon is still pertinent: “Who can say, I have made my heart clean, I am pure from my sin?” Prov. 20:9. Moreover, John says: “If we say that we have no sin, we deceive ourselves, and the truth is not in us,” I John 1:8. 

(4) The apostle John declares explicitly that they who are born of God do not sin, I John 3:6, 8, 9; 5:18. But when John says that they who are born of God do not sin, he is contrasting the two states, represented by the old and the new man, as to their essential nature and principle. One of the essential characteristics of the new man is that he does not sin. In view of the fact that John invariably uses´ the present to express the idea that the one born of God does not sin, it is possible that he desires to express the idea that the child of God does not go on sinning habitually, as the devil does, I John 3:8. [1] He certainly does not mean to assert that the believer never commits an act of sin, cf.  I John 1:8-10. Moreover, the Perfectionist cannot very well use these passages to prove his point, since they would prove too much for his purpose. He does not make bold to say that all believers are actually sinless, but only that they can reach a state of sinless perfection. The Johannine passages, however, would prove, on his interpretation, that all believers are without sin. And more than that, they would also prove that believers never fall from the state of grace (for this is sinning); and yet the Perfectionists are the very people who believe that even perfect Christians may fall away. 

c. Objections to the theory of Perfectionism. 

(1) In the light of Scripture the doctrine of Perfectionism is absolutely untenable. The Bible gives us the explicit and very definite assurance that there is no one on earth who does not sin, I Kings 8:46; Prov. 20:9; Eccl. 7:20; ROM 3:10; Jas. 3:2; I John 1:8. In view of these clear statements of Scripture it is hard to see how any who claim to believe the Bible as the infallible Word of God can hold that it is possible for believers to lead sinless lives, and that some actually succeed in avoiding all sin. 

(2) According to Scripture there is a constant warfare between the flesh and the Spirit in the lives of God´s children, and even the best of them are still striving for perfection. Paul gives a very striking description of this struggle in ROM 7:7-26, a passage which certainly refers to him in his regenerate state.  In Gal. 5:16-24 he speaks of that very same struggle as a struggle that characterizes all the children of God. And in Phil. 3:10-14 he speaks of himself, practically at the end of his career, as one who has not yet reached perfection  but is pressing on toward the goal. 

(3) Confession of sin and prayer for forgiveness are continually required. Jesus taught all His disciples without any exception to pray for the forgiveness of sins and for deliverance from temptation and from the evil one, Matt. 6:12, 13.  And John says: “If we confess our sins, He is faithful and righteous to forgive us our sins, and to cleanse us from all unrighteousness,” I John 1:9. Moreover, Bible saints are constantly represented as confessing their sins, Job 9:3, 20; Ps. 32:5, 130:3; 143:2; Prov. 20:9; Isa. 64:6; Dan, 9:16; ROM 7:14. 

(4) The Perfectionists themselves deem it necessary to lower the standard of the law and to externalize the idea of sin, in order to maintain their theory.  Moreover, some of them have repeatedly modified the ideal to which, in their estimation, believers can attain. At first the ideal was “freedom from all sin”; then, “freedom from all conscious sin,” next, “entire consecration to God,” and, finally, “Christian assurance.” This is in itself a sufficient condemnation of their theory. We naturally do not deny that the Christian can attain to the assurance of faith.

It is of considerable importance to have a correct conception of the relation between sanctification and some of the other stages in the work of redemption. 

There is both difference and similarity here. Regeneration is completed at once, for a man cannot be more or less regenerated; he is either dead or alive spiritually. Sanctification is a process, bringing about gradual changes, so that different grades may be distinguished in the resulting holiness. Hence we are admonished to perfect holiness in the fear of the Lord, II Cor. 7:1. The Heidelberg Catechism also presupposes that there are degrees of holiness, when it says that even “the holiest men, when in this life, have only a small beginning of this obedience.” [1] At the same time regeneration is the beginning of sanctification. The work of renewal, begun in the former, is continued in the latter, Phil. 1:6. Strong says: “It (sanctification) is distinguished from regeneration as growth from birth, or as the strengthening of a holy disposition from the original impartation of it.” [2] 

Justification precedes and is basic to sanctification in the covenant of grace. In the covenant of works the order of righteousness and holiness was just the reverse. Adam was created with a holy disposition and inclination to serve God, but on the basis of this holiness he had to work out the righteousness that would entitle him to eternal life. Justification is the judicial basis for sanctification. God has the right to demand of us holiness of life, but because we cannot work out this holiness for ourselves, He freely works it within us through the Holy Spirit on the basis of the righteousness of Jesus Christ, which is imputed to us in justification. The very fact that it is based on justification, in which the free grace of God stands out with the greatest prominence, excludes the idea that we can ever merit anything in sanctification.  The Roman Catholic idea that justification enables man to perform meritorious works is contrary to Scripture. Justification as such does not effect a change in our inner being and therefore needs sanctification as its complement. It is not sufficient that the sinner stands righteous before God; he must also be holy in his inmost life. Barth has a rather unusual representation of the relation between justification and sanctification. In order to ward off all self-righteousness, he insists on it that the two always be considered jointly. They go together and should not be considered quantitatively, as if the one followed the other. Justification is not a station which one passes, an accomplished fact on the basis of which one next proceeds to the highway of sanctification. It is not a completed fact to which one can look back with definite assurance, but occurs ever anew whenever man has reached the point of complete despair, and then goes hand in hand with sanctification. And just as man remains a sinner even after justification, so he also remains a sinner in sanctification, even his best deeds continue to be sins. Sanctification does not engender a holy disposition, and does not gradually purify man. It does not put him in possession of any personal holiness, does not make him a saint, but leaves him a sinner. It really becomes a declarative act like justification. McConnachie, who is a very sympathetic interpreter of Barth, says: “Justification and sanctification are, therefore, to Barth, two sides of one act of God upon men. Justification is the pardon of the sinner (justificatio impii), by which God declares the sinner righteous. Sanctification is the sanctification of the sinner (sanctificatio impii), by which God declares the sinner ‘holy´.” However laudable the desire of Barth to destroy every vestige of work-righteousness, he certainly goes to an unwarranted extreme, in which he virtually confuses justification and sanctification, negatives the Christian life, and rules out the possibility of confident assurance. 

Faith is the mediate or instrumental cause of sanctification as well as of justification. It does not merit sanctification any more than it does justification, but it unites´ us to Christ and keeps us in touch with Him as the Head of the new humanity, who is the source of the new life within us, and also of our progressive sanctification, through the operation of the Holy Spirit.  The consciousness of the fact that sanctification is based on justification, and is impossible on any other basis, and that the constant exercise of faith is necessary, in order to advance in the way of holiness, will guard us against all self-righteousness in our striving to advance in godliness and holiness of life. It deserves particular attention that, while even the weakest faith mediates a prefect justification, the degree of sanctification is commensurate with the strength of the Christian´s faith and the persistence with which he apprehends Christ.
