The Roman Empire aid the spread of Christianity in many ways. Because the Romans are tolerate of religion, Christianity spread much faster. Around when Christianity was rising, Rome starts to decline, so there are a lot of poor people and the poor tends to like Christianity a lot. St. Paul also aid in the spread of Christianity, he set up the doctrines that are the basis for Christianity which was: Jesus was sent by God to redeem humanity from sins, all humans are sinful because of Adam and Eve, by dying on the cross, Jesus made it possible for humans to be saved, anyone could be saved through faith in God.
Christianity is so appealing to so many people in the Roman Empire because it give people ideas of why things happen the way it is. It was simple; it only has one god who is the creator of everything rather then the old complex religion which is a bunch of gods for everything there is. It explains why theres evil in the unisverse and what is evil. It gives the people a sense of moral structure of the universe. The idea of God guaranteeds safety and justice to all gave followers a sense of community and fellowship to the people. It was available to ordinary folks rather than just the higher class.
