Pelagius was an ascetic monk and lay theologian in the early church who denied the doctrine of original sin from Adam. He was eventually declared a heretic by the Roman Catholic Church. His doctrine of a free will became commonly known as Pelagianism, which was strongly opposed by Augustine of Hippo.
