The most important event in human history apart from the life, death and resurrection of Jesus of Nazareth is the conversion to Christianity of Saul of Tarsus. If Saul had remained a Jewish rabbi, we would be missing thirteen of twenty-seven books of the New Testament and Christianity's early major expansion to the Gentiles. Humanly speaking, without Paul Christianity would probably be of only antiquarian or arcane interest, like the Dead Sea Scrolls community or the Samaritans.
