Acts 15:7-9
vs 7 And when there had been much dispute, Peter rose up and said to them: “Men and brethren, you know that a good while ago God chose among us, that by my mouth the Gentiles should hear the word of the gospel and believe.
vs 8 So God, who knows the heart, acknowledged them by giving them the Holy Spirit, just as He did to us,
vs 9 and made no distinction between us and them, purifying their hearts by faith.
