A couple of the comments here made me reflect upon the sad reality that within American Orthodoxy, we just talk the talk about a unified Church. The truth is that many lay people have little recognition or understanding about the diversity that exists here in terms of jurisdictions and sitting Bishops. Pittsburgh, Pa, for example has several Orthodox Bishops, Bishop Melchizedek of the OCA, Metropolitan Constantine of the UOC-USA, Bishop Mitrophan of the Serbs (His address is Mars, PA but....really partof metro Pgh.) and Metropolitan Maximos of the Greek Orthodox Archdiocese of America. This in addition to those nearby, including the vacancy in Johnstown, PA (although that see is not geographic in the traditional sense.) as well as the Antiochian Bishop in Charlestown, West Va. These are just the Episcopal Assembly/SCOBA hierarchs. There may be others there who are not EA.
Even among involved parishioners, cradle and convert alike, many tend to view the 'other' Orthodox in town as being like Lutherans are to Methodists are to Baptists etc....rather than being representatives of the Same Faith. How do we get beyond that before we unite?
