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).
