Pelagius

Pelagius (/pəˈleɪdʒiəs/; fl. c. 354–418) was a British (Brittonic) theologian known for promoting a system of doctrines (termed Pelagianism by his opponents) which emphasized human choice in salvation and denied original sin. Pelagius was accused of heresy at the Synod of Diospolis in 415 and his doctrines were harshly criticized by Augustine of Hippo, especially the Pelagian views about mankind's good nature and individual responsibility for choosing asceticism. Pelagius especially stressed the freedom of human will. Very little is known about the personal life and career of Pelagius.
