Excerpts from Books and Wikipedia
"After a revelation on the road to Damascus, Saul becomes Paul and begins spreading the word of Christ throughout the eastern Mediterranean. . . . Whereas many of the other leaders of the early Church had known Jesus personally, Paul's experience of him was limited to the revelation on the road to Damascus. Perhaps as a result of this, he stressed the transforming power of faith in the risen Christ, rather than the words and deed of Jesus during his ministry." [1001 Days]
