I think some of these instances are simply people over-eager to get on with ecumenism. But what's the point? It's silly superficialities, taking Orthodoxy down a level.
I'm happy to discuss my faith with a Baptist, a Roman Catholic, or a Hindu, but I'm not going to say we all believe the same thing just to make them happy.
One of the problems with Orthodoxy in America is that we have spent so long trying to be like others, trying to fit in. For what end? So we too could be good Episcopalians or good Baptists? I think things would have turned out better had we just kept to ourselves, being strong witnesses for the faith, removing the organ music from our sanctuaries! (talk about tasteless and plastic.....)
