In the beginning, why was Christianity so popular even when it was outlawed by the Roman Empire? Describe how the Roman Empire was eventually responsible for the spread of Christianity.
The triumph of Christianity is actually a very remarkable historical phenomenon. ... We begin with a small group from the backwaters of the Roman Empire and after two, three centuries go by, lo and behold that same group and its descendants have somehow taken over the Roman Empire and have become the official religion, in fact the only tolerated religion, of the Roman Empire by the end of the 4th century. That is a truly remarkable development, and a monumental historical problem, trying to understand how this happened. Of course, pious Christians have no doubt about how or why it happened: "This is the hand of God working in history." And the Christians of antiquity already made this very point; the fact that Christianity triumphed is proof of its truth.
