151 Then certain individuals came down from Judea and were teaching the brothers, "Unless you are circumcised according to the custom of Moses, you cannot be saved." 2 And after Paul and Barnabas had no small dissension and debate with them, Paul and Barnabas and some of the others were appointed to go up to Jerusalem to discuss this question with the apostles and the elders. 3 So they were sent on their way by the church, and as they passed through both Phoenicia and Samaria, they reported the conversion of the Gentiles, and brought great joy to all the believers. 4 When they came to Jerusalem, they were welcomed by the church and the apostles and the elders, and they reported all that God had done with them.

Commentary on Acts 15:1-6
(Read Acts 15:1-6)
Some from Judea taught the Gentile converts at Antioch, that they could not be saved, unless they observed the whole ceremonial law as given by Moses; and thus they sought to destroy Christian liberty. There is a strange proneness in us to think that all do wrong who do not just as we do. Their doctrine was very discouraging. Wise and good men desire to avoid contests and disputes as far as they can; yet when false teachers oppose the main truths of the gospel, or bring in hurtful doctrines, we must not decline to oppose them.
