Acts 15:3-5

3And being brought on their way by the church, they passed through Phenice and Samaria, declaring the conversion of the Gentiles: and they caused great joy unto all the brethren.

4And when they were come to Jerusalem, they were received of the church, and of the apostles and elders, and they declared all things that God had done with them.

5But 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.
