Why was Christianity so popular in western Europe in medieval times?

Answer 1

Perhaps Christians were a bit harsh in the spreading of their own religion. They burned witches, but they also died and suffered for their own beliefs. They too were tortured and persecuted by the Romans. The Bible teaches that. But does it really matter why Christianity is so popular? You must choose your own path. You must choose for yourself what you think is right. I strayed from Christianity to pursue Wicca. A pagan religion. Pagans did sacrifice people a long time ago. So yes, there is something wrong with every religion. No one is perfect. Not Christians. Not wiccans. No one. We are all human.AnswerNobody had been able to unite Europe, primarily because of their divergent beliefs. Constantine mandated that all Europeans accept his "Universal" religion, which was a melding of the many belief systems with a minor sect of Judaism.

The religion became "popular" because if you refused to join it, you were executed.

Answer 2

In Europe, the main religion was Christianity because at the end of the Roman Empire, the most widespread religion was Christianity. There were no denominations, as none had been developed yet. All those professing Christianity professed the Catholic version.
