151 And certain persons, having come down from Judaea, taught the brethren, If ye shall not have been circumcised according to the custom of Moses, ye cannot be saved. 2 A commotion therefore having taken place, and no small discussion on the part of Paul and Barnabas against them, they arranged that Paul and Barnabas, and certain others from amongst them, should go up to Jerusalem to the apostles and elders about this question. 3 They therefore, having been set on their way by the assembly, passed through Phoenicia and Samaria, relating the conversion of [those of] the nations. And they caused great joy to all the brethren. 4 And being arrived at Jerusalem, they were received by the assembly, and the apostles, and the elders, and related all that God had wrought with them.

(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.
