Acts 11:2
“When Peter had come up to Jerusalem, those who were of the circumcision contended with him,”
What does Acts 11:2 mean?
When Peter returned to Jerusalem after visiting non-Jewish believers, some Jewish Christians challenged him about what he'd been doing. These "circumcision" believers were concerned that Peter might be breaking Jewish laws by spending time with people outside their tradition. Peter's critics weren't hostile people, but they were anxious about how the gospel was spreading beyond the boundaries they thought were necessary, and they wanted answers from their respected leader.
