The Acts 15:7-9

And when there had been much disputing, Peter, rising up, said to them: Men, brethren, you know, that in former days God made choice among us, that by my mouth the Gentiles should hear the word of the gospel, and believe. And God, who knoweth the hearts, gave testimony, giving unto them the Holy Ghost, as well as to us; And put no difference between us and them, purifying their hearts by faith.
