This seems to me to one of the more productive ways of handling the confusion. The Orthodox Church's position on ecumenism is that they know where grace is; they don't know where grace isn't. It seems to me helpful to focus on where grace is. That is not to say that we don't look for ways to share and spread that grace--not at all. In fact, one of the difficulties of our denomination presently is that we have lost the missionary zeal we once had. This strategy simply shores up where we know grace is and it advertises that grace is HERE! Pontificating, on the other hand, about where grace isn't, and then divorcing ourselves from party's that we esteem to be arid of grace, strikes me as neither productive nor faithful.
