21:21 That thou teachest, etc. Paul, in advance of the rest, had learned that the Jewish forms were not to be imposed upon Gentiles, were not an obligation upon Jewish Christians, but he still observed them, at least in part, himself, and so far from bidding Jewish brethren to forsake Moses, he circumcised Timothy (Ac 16:3), and said, Let every man abide in the same calling (whether Jew or Gentile) in which he is called. Read the whole connection of 1Co 7:18-20. He had not, therefore, taught Jews to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs.
21:21 They have been informed concerning thee, that thou teachest the Jews - not to circumcise their children, nor to walk after the customs - Of the Mosaic law. And so undoubtedly he did. And so he wrote to all the Churches in Galatia, among whom were many Jews. Yea, and James himself had long before assented to Peter, affirming before all the apostles and all the brethren, Acts 15:10, That this very law was a yoke which (said he) neither our fathers nor we were able to bear - Amazing! that they did not know this! Or, that if they did, they did not openly testify it at all hazards, to every Jewish convert in Jerusalem!
21:19-26 Paul ascribed all his success to God, and to God they gave the praise. God had honoured him more than any of the apostles, yet they did not envy him; but on the contrary, glorified the Lord. They could not do more to encourage Paul to go on cheerfully in his work. James and the elders of the church at Jerusalem, asked Paul to gratify the believing Jews, by some compliance with the ceremonial law. They thought it was prudent in him to conform thus far. It was great weakness to be so fond of the shadows, when the substance was come. The religion Paul preached, tended not to destroy the law, but to fulfil it. He preached Christ, the end of the law for righteousness, and repentance and faith, in which we are to make great use of the law. The weakness and evil of the human heart strongly appear, when we consider how many, even of the disciples of Christ, had not due regard to the most eminent minister that even lived. Not the excellence of his character, nor the success with which God blessed his labours, could gain their esteem and affection, seeing that he did not render the same respect as themselves to mere ceremonial observances. How watchful should we be against prejudices! The apostles were not free from blame in all they did; and it would be hard to defend Paul from the charge of giving way too much in this matter. It is vain to attempt to court the favour of zealots, or bigots to a party. This compliance of Paul did not answer, for the very thing by which he hoped to pacify the Jews, provoked them, and brought him into trouble. But the all-wise God overruled both their advice and Paul's compliance with it, to serve a better purpose than was intended. It was in vain to think of pleasing men who would be pleased with nothing but the rooting out of Christianity. Integrity and uprightness will be more likely to preserve us than insincere compliances. And it should warn us not to press men to doing what is contrary to their own judgment to oblige us.
