John Calvin on Acts 15:21

21. For Moses hath. This place, in my judgment, hath been badly expounded, and drawn into a contrary sense. For interpreters think that James addeth this, because it were superfluous to prescribe anything to the Jews, who were well acquainted with the doctrine of the law, and to whom it was read every Sabbath-day; and they pick out this meaning, Let us be content to require these few things at the hands of the Gentiles, which are not accustomed to bear the yoke of the law; as touching the Jews they have Moses, out of whom they may learn more. Some do also gather out of this place, that circumcision, with its appurtenances, ought to be observed even at this day among the Jews. But they reason unfitly and unskillfully, though that exposition which I have set down “Quam retuli,” to which I have referred were true. But James had a far other meaning; to wit, he teachers that it cannot be that ceremonies can be abolished so quickly, as it were, at the first dash; because the Jews had now a long time been acquainted with the doctrine of the law, and Moses had his preachers; therefore, it stood them upon to redeem concord for a short thee, until such time as the liberty gotten by Christ might, by little and little, appear more plainly. This is that which is said in the common proverb, That it was meet that the old ceremonies should be buried with some honor. Those who are skillful in the Greek tongue shall know that that last member, When he is read every Sabbath-day in the synagogues, was by me changed not without cause, for avoiding of doubtfulness. “Nempe, vitandae ambiguitatis causa,” namely, for the purpose of avoiding ambiguity.

Acts 15:22-29

22. Then it seemed good to the apostles and elders, with the whole church, to send chosen men of them to Antioch, with Paul and Barnabas, Judas, surnamed Barsabas, and Silas, chief men among the brethren. 23. Sending letters by their hands after this form: The apostles, and elders, and brethren, to those brethren which are at Antioch, and in Syria and Gilicia, which are of the Gentiles, greeting: 24. Because we have heard that certain which went out from us have troubled you with words, subverting your souls, commanding you to be circumcised, and to keep the law, to whom we gave no commandment; 25. It seemed good to us, being gathered together with one mind, to send chosen men to you, with our beloved Barnabas and Paul; 26. Men which have ventured their souls for the name of our Lord Jesus Christ. 27. Therefore we have sent Judas and Silas, who shall also tell you the same things by word of mouth. 28. For it seemed good to the Holy Ghost and us, to lay no greater burden upon you than these necessary things, 29. That ye abstain from those things which are sacrificed to images, and from blood, and from that which is strangled, and from fornication; from which things, if you shall keep yourselves, ye shall do well. Fare ye well.
