Matthew Henry on 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.
