151 And certain men came down from Judaea and taught the brethren, [saying], Except ye be circumcised after the custom of Moses, ye cannot be saved. 2 And when Paul and Barnabas had no small dissension and questioning with them, [the brethren] appointed that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question. 3 They therefore, being brought on their way by the church, passed through both Phoenicia and Samaria, declaring the conversion of the Gentiles: and they caused great joy unto all the brethren. 4 And when they were come to Jerusalem, they were received of the church and the apostles and the elders, and they rehearsed all things 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.
