Acts 9, 22, and 26 do not match in detail. Luke was not covering a fraud. He was retelling a call. Harmony is a prosecutor’s demand, not scripture’s. The Church’s First Vision essay says the same about Joseph: consistent story, different emphasis.

KJV · Suddenly there shined round about him a light from heaven… Saul, Saul, why persecutest thou me?
NRSVUE · Suddenly a light from heaven flashed around him… ‘Saul, Saul, why do you persecute me?’
