Open Origin Religions?

[Aractus]

Quick question for you all:

a.) Judaism was founded when Moses went up Mt. Sinai on his own, and received the 2 stone tablets with the 10 commandments written on them.
b.) Christianity was founded, at best in Jesus' mind, or at worst in Paul's.
c.) Mormonism was founded when Joseph Smith got special glasses to read his magical rock.
d.) Islam was founded when Muhammed singularly received revelation from Allah.

It seems to me that all religions I am aware of were formed by single people, with experiences that only they experienced. Do you know of any religion that was formed by committee, meaning it was open-source, and many people experienced whatever phenomenal thing was being reported?

Judaism was not founded by Moses, it's an archaeological fact that he never set foot on Mt. Sinai. It was founded by collaboration, as evidenced by the fact that each of the books of the Pentateuch were written down by multiple authors, sometime around the 8th century BC.

Christianity was founded by the followers of Jesus, between Peter, Paul, James the Just, Luke, and other early figures. It was founded by collaboration. Note that in Acts a decision is reached not to require Greeks to be circumcised, this was not something suggested at anytime by Jesus it was decided at the Jerusalem Council. In fact until the Jerusalem Council you would say there were several competing "brands" of early followers of Jesus and that that's the point they became a unified religion. That was the point from which things started being written down, circulated, copied, and then put into the Bible or discarded as heresies.

Mormonism and Islam were founded by single figures as you suggest, as was Scientology.
