One of my favorite verses.
The question has been answered by you and others fully. There is only one reason it keeps being asked: Trolling. I suggest, do not feed the trolls. But the next time I see this stuff being done to an interesting Catholic thread, I will hit the abuse button. This is nothing but trolling abuse of Catholics.
I suspect protestants do this because they have no peace among themselves, and nit pick over their beliefs so much, and envy Catholic clarity.
