We teach in this matter, which at all times has been the cause of many conflicts in the church, that there is a triple condition or estate of man to be considered. First, what man was before his fall; to wit, upright and free, who might both continue in goodness and decline to evil; but he declined to evil and has wrapped both himself and all mankind in sin and death, as has been shown before. Secondly, we are to consider what man was after his fall. His understanding indeed was not taken from him, neither was he deprived of will and altogether changed into a stone or stock. Nevertheless, these things are so altered in man that they are not able to do that now which they could do before his fall. For his understanding is darkened, and his will, which before was free, is now become a servile will; for it serves sin, not nilling, but willing; for it is called a will, and not a nill.
Therefore, as touching evil or sin, man does evil, not compelled either by God or the devil, but of his own accord; and in this respect he has a most free will: but whereas we see that oftentimes the most evil deeds and counsels of man are hindered by God, that they cannot attain to their end, this does not take from man liberty in evil, but God by His power prevents that which man otherwise purposed freely: as Joseph's brethren did freely purpose to slay Joseph; but they were not able to do it because it seemed otherwise good to God in His secret counsel.
But as touching goodness and virtues, man's understanding does not of itself judge aright of heavenly things. For the evangelical and apostolic Scripture requires regeneration of every one of us that will be saved. Wherefore our first birth by Adam profits nothing to salvation. Paul says, "The natural man perceiveth not the things which are of the Spirit" (1 Cor. 2:14). The same Paul elsewhere denies that we are "fit of ourselves, to think any good" (2 Cor. 3:5). Now it is evident that the mind or understanding is the guide of the will; and seeing the guide is blind, it is easy to be seen how far the will can reach. Therefore, man, not as yet regenerate, has no free will to good, no strength to perform that which is good. The Lord says in the gospel, "Verily, verily, I say unto you, that every one that commits sin, is the servant of sin" (John 8:34). And Paul the apostle says, "The wisdom of the flesh is enmity against God: for it is not subject to the law of God, neither indeed can be" (Rom. 8:7). Furthermore, there is some understanding of earthly things remaining in man after his fall.
For God has of mercy left him wit, though much differing from that which was in him before his fall; God commands us to cultivate our wit, and therewithal He gives gifts and also the increase thereof. And it is a clear case that we can profit very little in all arts without the blessing of God. The Scripture, doubtless, refers all arts to God: yes and the Ethnicks also did ascribe the beginnings of arts to the gods, as to the authors thereof.
Lastly, we are to consider whether the regenerate have free will and how far forth they have it. In regeneration, the understanding is illuminated by the Holy Ghost that it may understand both the mysteries and will of God. And the will itself is not only changed by the Spirit, but is also endued with faculties, that, of its own accord, it may both will and do good (Rom. 8:4–6). Unless we grant this, we shall deny Christian liberty and bring in the bondage of the Law. Besides, the prophet brings in God speaking thus: "I will put My laws in their minds, and write them in their hearts" (Jer. 31:33; Ezek. 36:27). The Lord also says in the gospel, "If the Son make you free, then are you free indeed" (John 8:36). Paul also to the Philippians: "Unto you it is given, for Christ, not only to believe in Him, but also to suffer for His sake" (1:29). And again, "I am persuaded that He that began this good work in you will perform it until the day of the Lord Jesus" (v. 6). Also, "It is God that worketh in you the will and the deed" (Phil. 2:13).
Where, nevertheless, we teach that there are two things to be observed: first, that the regenerate, in the choice and working of that which is good, do not only work passively, but actively. For they are moved of God, that themselves may do that which they do. And Augustine truly alleges that saying that "God is said to be our helper: but no man can be helped, but he that does somewhat." The Manichees robbed man of all action and made him like a stone and a block.
Secondly, that in the regenerate there remains infirmity. For seeing that sin dwells in us and that the flesh in the regenerate strives against the spirit, even to the end of our lives, they do not readily perform in every point that which they had purposed. These things are confirmed by the apostle (Rom. 7:13–25; Gal. 5:17). Therefore, our free will is weak by reason of the relics of the old Adam remaining in us so long as we live, and of the human corruption which so nearly cleaves to us. In the meantime, because the strength of the flesh and relics of the old man are not of such great force that they can wholly quench the work of the Spirit, therefore, the faithful are called free; yet so that they acknowledge their infirmity and glory not at all in their free will. For that which St. Augustine repeats so often out of the apostle ought always to be kept in mind by the faithful: "What hast thou, that thou hast not received? and if thou hast received it, why dost thou boast, as though thou hadst not received it?" (1 Cor. 4:7). Hitherto may be added that that comes not straightway to pass which we have purposed: for the events of things are in the hand of God. For which cause, Paul besought the Lord that He would prosper his journey (Rom. 1:10). Wherefore, in this respect also, free will is very weak.
But in outward things, no man denies but that both the regenerate and unregenerate have their free will. For man has this constitution common with other creatures (to whom he is not inferior) to will some things and to nill other things. So he may speak or keep silence; go out of his house or abide within. Although herein also God's power is evermore to be marked which brought to pass that Balaam could not go as far as he would (Num. 24:13) and that Zacharias, coming out of the Temple, could not speak as he would have done (Luke 1:22).
In this matter we condemn the Manichees, who deny that the beginning of evil unto man, being good, came from his free will. We condemn also the Pelagians who affirm that an evil man has free will sufficiently to perform a good precept. Both these are confuted by the Scripture, which says to the former, "God made man upright" (Eccl. 7:29) and to the latter, "If the Son make you free, then are you free indeed" (John 8:36).
