Whoever these "some" are, they'd better get over it, don't you think, Serge?
The OCA, and especially since it was formally granted a Tomos of Autocephaly by the MP in 1970, does *not* consider itself to be part of the MP, and neither does the MP consider the OCA to be part of the MP. Both the MP and the OCA recognize the OCA as a completely separate and independent eccesial entity, indeed, as a canonical Autocephalous Orthodox Church. The clock won't turn backwards on the OCA's autocephaly, despite the sometimes shrill voices of its detractors.
Getting back to the differences in recensions in the Liturgy of the Presanctified between the ROCOR and the OCA, I've been given the impression that even the order of some of the prayers, if not some of the prayers themselves, may be different. Any liturgical experts "in the know" about this? The only way, I'm told, that I can find out is to actually attend a Presanctified Liturgy in a ROCOR church (not likely with my choir commitments at my OCA church this year), but surely there must be someone who has access both to the ROCOR and the OCA's texts and rubrics for this Lenten service and can tell us the differences here.
