“And when Peter was come up to Jerusalem, they that were of the circumcision contended with him,”
King James Version (KJV)
Ac 11:2 They that were of the circumcision contended with him. The Jewish Christians, of whom the church at Jerusalem was entirely composed. The Gentiles of Caesarea were the first uncircumcised persons admitted, the Samaritans being a circumcised people. The apostles and church generally seemed to understand that Jesus was the world's Savior, but thought that all who came to him must accept Judaism also and be circumcised before baptism. How deep-rooted their ideas were is shown by Peter's own case. It took (1) a vision, (2) the command of the Lord, (3) the call of Cornelius, and (4) the descent of the Holy Spirit on the Gentiles, to remove his and his brethren's scruples about baptizing the Gentiles. It is, therefore, no wonder that his course was called in question.
