Pelagius (c. 360 – 418) was a British-born
ascetic moralist, who became well known throughout
ancient Rome. He opposed the idea of
predestination and asserted a strong version of the doctrine of
free will. He was accused by
Augustine of Hippo and others of denying the need for divine aid in performing
good works. They understood him to have said that the only grace necessary was the declaration of the law; humans were not wounded by Adam's sin and were perfectly able to fulfill the law without divine aid. Pelagius denied Augustine's theory of
original sin. His adherents cited Deuteronomy 24:16 in support of their position. Pelagius was declared a
heretic by the
Council of Carthage. His interpretation of a doctrine of
free will became known as
Pelagianism.
