Acts 9:10 describes Ananias as a disciple in Damascus, while Acts 22:12 mentions him as a devout man according to the law, without indicating he was a disciple.

Contradiction with Acts 9:2
In Acts 9:10, Ananias is depicted as a follower of Jesus, but in Acts 9:2, Saul's mission was to persecute those who followed "this way," possibly suggesting opposition to disciples like Ananias.
Acts 9:2: And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem. [of this way: Gr. of the way]
