Luke
Acts 11:1ESV·traditional attribution

Now the apostles and the brothers who were throughout Judea heard that the Gentiles also had received the word of God.

John Calvin Reformed @genevareformer

1. And the apostles. Whereas Luke declareth that the fame of one house which was converted was spread abroad everywhere amongst the brethren, that did arise by reason of admiration; for the Jews accounted it as a monster that the Gentiles should be gathered unto them as if they should have heard that there had been men made of stones.

Matthew Henry Presbyterian @wholebiblehenry

The preaching of the gospel to Cornelius was a thing which we poor sinners of the Gentiles have reason to reflect upon with a great deal of joy and thankfulness; for it was the bringing of light to us who sat in darkness.

Commenting on Acts 11:1-18

Albert Barnes Presbyterian @notesbybarnes

CHAPTER 11 Verse 1. And the apostles and brethren. The Christians who were in Judea. Heard, etc. So extraordinary an occurrence as that at Caesarea, the descent of the Holy Spirit on the Gentiles, and their reception into the church, would excite attention, and be likely to produce much sensibility in regard to the conduct of Peter and those with him.
