Matt Slick of CARM wrote that “Pelagianism…. taught that people had the ability to fulfill the commands of God by exercising the freedom of human will apart from the grace of God. In other words, a person’s free will is totally capable of choosing God and/or to do good or bad without the aid of Divine intervention.”
This description of “Pelagianism” by Matt Slick is an example, not of Pelagian heresy, but of Pelagian hearsay.
I would suspect that Matt Slick learned about Pelagianism from its opponents, and not from actually reading the writings of the Pelagians. This is a common practice for Calvinists, but what if that is how their doctrine was treated? What if someone stated what Calvinism teaches, by stating the opponents? Augustine accused Pelagius of denying the grace of God, but this was an accusation not a fact.
Had Matt Slick actually read some of the few writings that still exist today from the original Pelagians, he would have read in the Pelagian Statement of Faith submitted to the Pope: “We [Pelagians] maintain that men are the work of God, and that no one is forced unwillingly by His power either into evil or good, but that man does either good or ill of his own will; but that in a good work he is always assisted by God’s grace, while in evil he is incited by the suggestions of the devil.”
Pelagius himself said, “I anathematize the man who either thinks or says that the grace of God, whereby ‘Christ Jesus came into the world to save sinners,’ is not necessary not only for ever hour and for every moment, but also for every act of our lives: and those who endeavor to dis-annul it deserve everlasting punishment.”
Pelagius said, “This grace we do not allow to consist only in the law but also in the help of God. God helps us through His teaching and revelation by opening the eyes of our heart, by pointing out to us the future so that we may not be preoccupied with the present, by uncovering the snares of the devil, by enlightening us with the manifold and ineffable gift of heavenly grace.”
Pelagius said, “God always aids by the help of his grace. God aids us by his doctrine and revelation, while he opens the eyes of our heart; while he shows us the future, that we may not be engrossed with the present; while he discloses the snares of the devil; while he illuminates us by the multiform and ineffable gift of heavenly grace. Does he who says this, appear to you to deny grace? Or does he appear to confess both divine grace and the freewill of man?”
Pelagius said in a letter to Innocent, “Behold, before your blessedness, this epistle clears me, in which we directly and simply say, that we have entire freewill to sin and not to sin, which, in all good works, is always assisted by divine aid. Let them read the letter which we wrote to that holy man, bishop Paulinus, nearly twelve years ago, which perhaps in three hundred lines supports nothing else but the grace and aid of God, and that we can do nothing at all of good without God. Let them also read the one we wrote to that sacred virgin of Christ, Demetrias, in the east, and they will find us so praising the nature of man, as that we may always add the aid of God’s grace. Let them likewise read my recent tract which we were lately compelled to put forth on freewill, and they will see how unjustly they glory in defaming us for denial of grace, who, through nearly the whole text of that work, perfectly and entirely profess both free will and grace.”
Pelagius taught that the freedom of the human will was not lost by the original sin of Adam, but that grace was necessary for man to rightly use his free will. He also taught that free will itself was a gracious gift given to us at Creation. He did not deny grace as necessary or as an aid for free will. The only grace he denied was Augustinian grace, which said that free will was lost by original sin and therefore man’s ability to obey needed to be restored by grace. However, one of the best Greek-English Lexicons, Thayer’s, defined grace as “divine influence upon the heart” which is precisely how Pelagius viewed grace in contradiction to Augustine.
