I’m not familiar with this you speak of. My point is, if John came to my church and asked to speak, I can’t imagine not allowing him. Remember the first church was Jews. The separation should NOT be. As an adopted son, I will lean always towards Israel and the Jews. They are more my brother than some “Christian” organizations. The Bible is our anchor. Denominations separate us.
I think if I am not mistaken, it was the early Christians who were driven out during the time of the apostles from the Jewish synagogues, not the other way around.
