Acts 15:7 (KJV)

But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses.

And the apostles and elders came together for to consider of this matter.

And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.

And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;

And put no difference between us and them, purifying their hearts by faith.
