Acts 15 and 16 Is Circumcision required for salvation?
The Jews, specifically the believing Pharisees, contended that for the Gentiles to be saved, they needed to be circumcised. Not so said Peter with his testimony about the salvation of Cornelius and his household. Paul agreed with him and expounded on it and will later write the book of Romans to justify why salvation is as Peter said. Circumcision is an outward ritual, and Paul explained that it must be Circumcision of the heart!
Further, Peter asked why do we want to add a burden that even the Jews have never been successful in keeping! So the dialog raged on until James stood up and proclaimed the truth from the OT. God said He would call the Gentiles to Himself for salvation, and it consisted of nothing more than repenting and believing in the name of Jesus.
James wrote a letter to the Gentile believers in Antioch, and the truth remains today: there is no outward ritual that one must keep. Just repent and believe, and you will be saved. That same message is still true today. Later, as Paul and Silas proclaimed that message to the residents of Philippi, the jailer came to believe it as well.
Today stop and praise God for the simplicity of the gospel message.
