"I get the impression from RC and EO that you folks are the only true church and the rest of us are off the bubble."
Well, yes. From a definitional point of view, goups of Christians outside the Orthodox, Roman Catholic and those Eastern Churches in communion with Rome, the Oriental Orthodox and likely some Lutheran dioceses (in my opinion)are not truly chuches at all but rather what +BXVI calls "ecclesial assemblies". We KNOW that theosis is found inside the Eucharistic Liturgical community of The Church. Outside The Church, well in Orthodoxy at least, we simply have no opinion.
Oh, brother. What a bunch of baloney.
