Was Christianity a anti-roman empire religion?
they give some lip service to cesear but overall are trying to undermine the authority of the emperor saying that there is a greater power and the rich elite are sinful/ people should not have so much kind of a socialism against luxury.
change the empire's culture and bring it down from within. make the greatest person in the empire from the emperor to someone tortured and executed by the empire and make everyone guilty feeling to be associated with the roman empire instead of proud.
And then catholisim was a attempt to co-opt the movement and integrate it into the empire but of course it failed.
