I kind of have been reading Saint Augustines "Confessions " in which he really speaks bad about the prophet Mani. It’s interesting to note it seems Manichaeism was a rival to the Church from the 4th to 7th centuries in Europe anyways. It lasted longer in the east.
Manichaeism somewhat reminds of of Islam. Both Mani and Muhammad claimed to be the paraclete spoken of in the New Testament. Also Jesus has an important role in both . It seems Manichaeism blended a lot of Zoroastrian beliefs as well with dualism.
So in a historical sense was Manichaeism a heresy of Christianity or was it a totally different world religion all together?
