Manicheism

According to Wikipedia, Manicheism was one of the major ancient religions of Iranian origin. Though its organized form is mostly extinct today, a revival has been attempted under the name of Neo-Manichaeism. However, most of the writings of the founding prophet Mani have been lost. Some scholars argue that its influence subtly continues in Western Christian thought via Saint Augustine of Hippo, who converted to Christianity from Manichaeism[1], which he passionately denounced in his writings, and whose writings continue to be enormously influential among Catholic, Protestant, and Orthodox theologians. Manichaeism originated in 3rd Century Babylon.
