Today’s readings tell us to have respect for members of the other Christian churches.
That is the message of the first reading. In it when Moses had gathered together seventy clan elders at one and the same moment they were all swept into a prophetic state. They felt God was speaking through them.
Now, there were two clan elders, Eldad and Medad, who had not been there when the others were swept into that prophetic state. It shocked the seventy when they witnessed Eldad and Medad prophesying like they had. But Moses told them not to feel bad about Eldad and Medad prophesying. God could have given them the spirit.
Similarly, in the Gospel when John tried to stop strangers from using Our Lord’s name to drive out demons, Jesus told him not to stop them. He told John, “Whoever is not against us is for us.”
Those of us who grew up before Vatican II did not know what the make of that advise. We had been told to stay clear of Protestants. We were told it was a sin to join with them in any religious activity. At Vatican II the Church confessed it had been wrong about that. In its document on Ecumenism it said, “Many of the elements and endowments which together give life to the Church can exist outside the visible boundaries of the Catholic Church.”
I don’t think the church has revoked Vatican II, Christians should be free to like and respect one another.
