Or they just read what is said about Jesus in the bible? Marx didn't invent the concept of helping the poor by sharing.

I mean, yeah probably. Jesus was pretty clearly a socialist, though I'm not studied enough in socialism or the bible to say which version of socialist he was.

Jesus was a communist (even if an utopian/idealist one)

Including their women. There are little hints. Paul seems worked up about permissive sex going around, the earliest Gospel has Jesus spend a surprisingly high amount of time, for a rabbi, alone with women. James and Cephus would need a motivation to keep the failing Jerusalem church going, Mary Magedlian seems to have made enemies where she is accused of being permissive (every conservative accusation is a confession), records of lots of children of James, and a cryptic stuff about how there would be no gender in the future and no gender before Jesus. The last line was uttered by a person who told people to unquestionably follow James.

History of early Christianity makes so much sense if you just treat it like any other cult. Sex, money, power. James and Cephus didn't have money or power so what else could it be?
