There are three stories of Paul’s conversion experience in the book of acts. The first is given by the author of Acts directly, as if recounting history, in chapter 9. In chapters 22 and 26, Paul is said to telling the story in his own words. Do not worry about the seemingly apparent contradictions between the three. This is a perfectly valid tactic used by ancient authors.
We are given two insights into Paul’s conversion (it is an anachronistic term, but you understand) in Galatians and in 1 Corinthians 15.3-6. But, what is said here is that Jesus appeared to Paul, just has he had to others. So, in all of Paul’s letters, there is no hint at the magnificent account of the Damascus Road event. We only get to read about this nearly a generation after Paul’s death.
Do not be so hasty as to assume that Luke is recounting a historical record, free of theologizing blemishes. This is simply not the way it was done, nor, if we are to be honest with ourselves, is done.
My question, consider that the last time I posted on Galatians and Paul’s story, is who is speaking in Acts. Is it Paul or is it Luke?
