[re: original sin (12th century): 12 minute and 21 second mark]
Where Did the Doctrine of Original Sin Come From? I don't suspect BL to be a Roman Catholic. AFAIK forgiveness and mercy, rather than guilt, are at the heart of the NT and the OT.
Israel was in exile at the time. Judah (a subpart of Israel) as a state, it is said, was coming to its end. Edom/Esau enemies of Israel and Judah (subpart of Israel) had taken chief positions in Judah after Hyrcanus forced integrated Edom/Esau into Judah. It is a matter of record that the Herods were Edomites. It has been suggested that Edom had come into alliance with Canaan and Ishmael.
Also, the scepter departed from Judah around 0 AD. Rabbinic Writings evidence this. This is further evidenced by the fact that the Judeans who wanted Jesus dead had to turn him over to the Romans to punish him.

But is it not interesting Mani and Simon Magus claimed to be Holy God, Christ, etc. but they had no problem with that? Simon Magus was made out to be a God in Rome some suggest.
Samson is said to have been of the tribe of Dan.
re: Original Sin
Related:The worst sins in Manichean thinking were the sexual sins, because they resulted in more souls of light becoming imprisoned in evil bodies. According to Manichaeism, mankind was divided into three separate groups of people: the Sinners, the Hearers and the Elect. The Elect were obliged to refrain from all things that bound them to the material world: certain foods, sexual intercourse and manual labor. They were certain to obtain salvation once they died. The Hearers had to observe the same restrictions only on Sundays.
The Manicheans called themselves Christians, which made it easier for someone raised Catholic to see himself as an adherent of something that was really Christianity...
NO ONE Before Augustine taught that man was Born a Sinner or that his Free Will was in bondage to his flesh. Such Teaching came from the Gnostics!
