Was Christianity started to control the masses and dictate poltical agendas

[Aegon]

I think the opposite, actually. Christianity was founded out a movement by the masses against those above them. Jesus was Luke Skywalker and the Roman Empire was... the Empire. I made a post similar to this several days ago, where I briefly discussed how Jesus is first and foremost a political figure, in my eyes and the eyes of many historians. That a mystical movement accompanied it is no surprise, considering they were Jews waiting for the messiah.

Christianity, like all religions, has been used to control people but I think you'd have to be willfully ignorant to think that that was the reason for its founding. It's too basic of an argument for an awfully nuanced debate that has yet to be resolved (and probably never will be.)
