LOL! "Saint" Augustine used to be a Manichean before he became a "Christian" around 400 C.E. He was a Manichean Gnostic (who are influenced by Zoroastrianism) and kept much of his Manichean theology and tried to tie it into Christianity.
The doctrines of: Corruption of the Physical Body, Innate Powerlessness, Eternal Salvation, Eternal Damnation, Defilement of Women, Pisticity (Faith-Onlyness) and disdain of spiritual knowledge, Classical Theism (God seperate from Self), Satan (God of Darkness), and Apocalyptism (literal Armageddon); are all philosophies borrowed from Manicheanism, Zoroastrianism, Stocism, and Neoplatonism (albeit in very bastardized form).
Sadly, this brutha was AFRICAN. Yep, you heard right. "Saint" Augustine was from Carthage, he was Afro-Phoenecian (he was Black, or at least Afro-Asiatic "Hamitic" like Berber peoples).
And sadly, the real enligthened figure who was his opponent was WHITE. Pelagius, a Christian philosopher with a very liberal theology that contradicted Augustinianism, WAS WHITE (he was a Druid Christian). Pelagius form of Christianity was eventually stomped out by the hyper-conservative Augustinian form of Christianity.
Pelagianism still survives in Scandanavian Christianity, and some schools of African and Middle Eastern Christianity.
