Council of Orange
CANON 1. If anyone denies that it is the whole man, that is, both body and soul, that was “changed for the worse” through the offense of Adam’s sin, but believes that the freedom of the soul remains unimpaired and that only the body is subject to corruption, he is deceived by the error of Pelagius and contradicts the scripture which says, “The soul that sins shall die” (Ezek. 18:20); and, “Do you not know that if you yield yourselves to anyone as obedient slaves, you are the slaves of the one whom you obey?” (Rom. 6:16); and, “For whatever overcomes a man, to that he is enslaved” (2 Pet. 2:19).
CANON 8. If anyone maintains that some are able to come to the grace of baptism by mercy but others through free will, which has manifestly been corrupted in all those who have been born after the transgression of the first man, it is proof that he has no place in the true faith. For he denies that the free will of all men has been weakened through the sin of the first man, or at least holds that it has been affected in such a way that they have still the ability to seek the mystery of eternal salvation by themselves without the revelation of God. The Lord himself shows how contradictory this is by declaring that no one is able to come to him “unless the Father who sent me draws him” (John 6:44), as he also says to Peter, “Blessed are you, Simon Bar-Jona! For flesh and blood has not revealed this to you, but my Father who is in heaven” (Matt. 16:17), and as the Apostle says, “No one can say ‘Jesus is Lord’ except by the Holy Spirit” (1 Cor. 12:3).
CANON 13. Concerning the restoration of free will. The freedom of will that was destroyed in the first man can be restored only by the grace of baptism, for what is lost can be returned only by the one who was able to give it. Hence the Truth itself declares: “So if the Son makes you free, you will be free indeed” (John 8:36).
Council of Trent
CANON 5. If anyone says that after the sin of Adam man’s free will was lost and destroyed, or that it is a thing only in name, indeed a name without a reality, a fiction introduced into the Church by Satan, let him be anathema.
