Acts 13-15, Proverbs 1

Certain people came down from Judea to Antioch and were teaching the believers: “Unless you are circumcised, according to the custom taught by Moses, you cannot be saved.” This brought Paul and Barnabas into sharp dispute and debate with them. So Paul and Barnabas were appointed, along with some other believers, to go up to Jerusalem to see the apostles and elders about this question. (Acts 15:1-2)

Anyone who wants to go back to the "good old days" when the church was "in full agreement" can take a lesson from the Bible's book of Acts, chapter 15. Sharp dispute and debate have been part of the church's experience from its very beginning. Here the debate concerns the practice of circumcision and its relevance to the church's teaching on salvation. 

Christ's church in the 21st century continues to debate what to do and what to teach. So, what did Jesus do, and what did he teach?
