Why on earth would you assume that there was no resistance to the Christian Church, particularly in the rural peasantry? In a world of minimal communication, surely the high-born and literate would be pulled into the new religion, but what makes you think that ordinary, ornery humans would 100% agree? Does anything else in human nature work this way? In Palestine, at least until a few years ago (I might have read this 10 years ago????) there still existed remnants of: Philistines, and also Samaritans. I think it was the Samaritans who were down to a few dozen. Now, that's orneriness. The Serbs have been trying to stamp out local Islam for a long time now. Have they succeeded? Don't read upper class history as the totality of history. Assume contrariness. You'll probably be right.
