Does Acts disagree with Epistles?

No. Paul in Acts & Romans 1 & 2 does preach repentance. Acts show Paul in Nazirite ceremony - in 1 Cor he says he was all things to all men. 2 Cor 11: Paul recounts his sufferings - in Acts we actually see them. How could Paul tell Corinthians they can eat meat sacrificed to idols, when Acts 15 forbids it. Only to converts in Syria and Cilicia-- when in that area Paul did preach rule of Acts 15.
