Leporius, formerly monk and afterwards presbyter, relying on purity, through his own free will and unaided effort, instead of depending on the help of God, began to follow the Pelagian doctrine.
However, having been admonished by Gallic doctors and corrected by Augustine in Africa, he wrote a book containing his retraction, in which he both acknowledges his error and expresses gratitude for his correction. Likewise, correcting his false view of the incarnation of Christ, he presented the Catholic view, acknowledging the single person of the Son of God, and the two natures existing in Christ in his substance.
