Acts 15:1-5

And certain men came down from Judæa and taught the brethren, saying, Except ye be circumcised after the custom of Moses, ye cannot be saved. And when Paul and Barnabas had no small dissension and questioning with them, the brethren appointed that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question. They therefore, being brought on their way by the church, passed through both Phoenicia and Samaria, declaring the conversion of the Gentiles: and they caused great joy unto all the brethren. And when they were come to Jerusalem, they were received of the church and the apostles and the elders, and they rehearsed all things that God had done with them. But there rose up certain of the sect of the Pharisees who believed, saying, It is needful to circumcise them, and to charge them to keep the law of Moses.
