Contradiction with Acts 9:26
This verse describes how the disciples were initially afraid of Saul, not believing he was a disciple, which seems to contradict the idea in Galatians 1:23 that people were readily accepting the news of his conversion.
Acts 9:26: And when Saul was come to Jerusalem, he assayed to join himself to the disciples: but they were all afraid of him, and believed not that he was a disciple.
