Pelagius (/pəˈleɪdʒiəs/; c. 354–418) was a British theologian known for promoting a system of doctrines (termed Pelagianism by his opponents) which emphasized human choice in salvation and denied original sin. Pelagius and his followers abhorred the moral standards of Christians in Rome, which he blamed on the view of divine grace. Pelagius was accused of heresy at the synod of Jerusalem in 415 and his doctrines were harshly criticized by Augustine of Hippo, especially the Pelagian views about humankind's good nature and individual responsibility for choosing ascetism. Pelagius especially stressed the freedom of human will. Very little is known about the personal life and career of Pelagius.
