John Chrysostom : "And the Apostles and brethren that were in Judea heard that the Gentiles had also received the word of God. And when Peter was come up to Jerusalem, they that were of the circumcision contended with him, saying, Thou wentest in to men uncircumcised, and didst eat with them." After such great things, "they of the circumcision contended:" not the Apostles; God forbid. It means, they took no small offence. And see what they allege. They do not say, Why didst thou preach? but, Why didst thou eat with them? But Peter, not stopping to notice this frigid objection - for frigid indeed it is - takes his stand on that great argument, If they had the Spirit Itself given them, how could one refuse to give them the baptism? — Homily on Acts 24 Oecumenius : Peter showed in his defense that he had by no means been the cause, but God everywhere. For he said, he himself set me in the excess of mind, he himself pointed out the sheet, and I indeed even contradicted; again the same he himself said, and I did not hear therefore. The Spirit commanded that I should join them, and having joined I did not even run on therefore. They said that God had sent, and I did not so baptize, but again God accomplished the whole matter. God baptized, not I. For while I was yet speaking, the Holy Spirit fell upon those men, and they spoke in tongues. They glorified God loudly, as do we. [CHRYSOSTOM] — Commentary on Acts
