Acts 11:2, 3 And when Peter came up to Jerusalem, those of the circumcision contended with him, saying, “You went in to uncircumcised men and ate with them!”
The familiar account of Peter recounting his encounter with Cornelius after his vision on the roof of the blanket with all kinds of animals in it and the revelation that what God calls clean is clean, even if it goes against conventional wisdom
There many takeaway’s from this event, one that is paramount deals with Kingdom activity.
Kingdom encounters supersedes human doctrines.
Religion is “rule” oriented; kingdom is “relational” oriented. When it comes to ministry to those least likely is confronted by rules, toss them and go with relationships.
Everything in Peter told him this was wrong, but rather than listening to the traditions (even in the young church) he yielded to the influence of the Kingdom. Recall Jesus spoke about the Kingdom more than any other topic during His 3+ years of earthly ministry. Perhaps it was the Kingdom Peter submitted to that created an effectual open door for ministry to an entirely different segment of the culture and humanity!
