They (the brethren) determined that Paul and Barnabas, and certain others should go up to Jerusalem about this question — This is the journey to which St. Paul refers, Galatians 2:1-2, when he says he went up by revelation: which is very consistent with this; for the Church in sending them might be directed by a revelation made either immediately to St. Paul, or to some other person, relating to so important an affair. Important indeed it was, that these Jewish impositions should be solemnly opposed in time; because multitudes of converts were still zealous for the law, and ready to contend for the observance of it. Indeed many of the Christians of Antioch would have acquiesced in the determination of Paul alone. But as many others might have prejudices against him, for his having been so much concerned for the Gentiles, it was highly expedient to take the concurrent judgment of all the apostles on this occasion.
