Peter recognised this immediately, and seizing the moment asked ‘the circumcised' whether they could think of any reason why these uncircumcised Gentiles should not be baptised when they had received the Holy Spirit in exactly the same way as they had. The answer could only be that they could think of no reason. But the significance of the reply and what followed was stupendous. It indicated that men could be baptised who were not circumcised in the flesh. No longer was circumcision required in order to become one of the people of God and enter Christ's new ‘congregation' (Matthew 16:18). All that was necessary was the circumcision of the heart (see Acts 7:51; Deuteronomy 10:16; Deuteronomy 30:6; Jeremiah 9:26), and to be circumcised in Christ by forgiveness (Colossians 2:13).
