Unlike the caucus threads, any poster could reply to an ecumenic thread. And the article on which an ecumenic thread is based could include contrasts and challenges of other beliefs. However, on the ecumenic thread, the poster must not argue against any other beliefs. He can only argue for what he believes – or ask questions. This sounds like it may take some getting used to (especially for newcomers), but I think it could also be very beneficial.
Glad to see you back, I will keep you and your family in my prayers.
God Bless (Or whatever the preferred phrase is if you are an anonymous non-Christian RM :-) )
