Many theologians, like Jerome and Augustine, respected Pelaguis's life and intent. Pelagius, himself a devout monk, convinced many wealthy Romans to do as he had done and forsake their possessions.
But as Pelagianism spread, it became an increasing problem for the church, and the aging Augustine worked fervently to stop it. At risk, believed Augustine, was the doctrine of grace. If humans are born without sin, what is the need for God's grace? And why not let humanity save itself by exercising free will and choosing to live the holy life? The biblical scholar Jerome joined Augustine in condemning Pelagius, calling him a "corpulent dog … weighed down with … porridge."
Pope Innocent I excommunicated Pelagius in 417. Though the monk was briefly restored by the new pope, Zosimus, in 418, Zosimus encountered such a storm from African bishops, where Augustine lived, that he changed his mind and wrote a letter condeming the Briton.
Pelagius disappeared from history, though his teachings endured for another century. The issues raised by Pelagianism reappeared many times in the Middle Ages and broke out afresh during the Reformation.
