If there are three different accounts of an event, it means, at least, two of the accounts are false, made up stories. If there would be four different accounts, then three of them would be false. In Acts 9, Acts 22 and Acts 26 there are three different versions of Paul’s conversion. Let’s see them:
… The men traveling with Saul stood there speechless; they heard the sound but did not see anyone. Saul got up from the ground, but when he opened his eyes he could see nothing. So they led him by the hand into Damascus. For three days he was blind, and did not eat or drink anything.
(In Acts 9, the companions saw nobody and heard a sound)
… My companions saw the light, but they did not understand the voice of him who was speaking to me. “‘What shall I do, Lord?’ I asked. “ ‘Get up,’ the Lord said, ‘and go into Damascus. There you will be told all that you have been assigned to do.’
(In Acts 22, the companions saw the light, and heard the sound)
“On one of these journeys I was going to Damascus with the authority and commission of the chief priests. About noon, King Agrippa, as I was on the road, I saw a light from heaven, brighter than the sun, blazing around me and my companions. We all fell to the ground, and I heard a voice saying to me in Aramaic, ‘Saul, Saul, why do you persecute me? It is hard for you to kick against the goads.’ “Then I asked, ‘Who are you, Lord?’
“ ‘I am Jesus, whom you are persecuting,’ the Lord replied.
(In Acts 26, the companions all shocked by the bright light and fell to the ground)
The differences in these three stories by the same author Luke tell us this: The Book of Acts is fiction and reality mixed. It is impossible today to tell what part of this Book of Acts was real and what part is the imagination of the author Luke.
