OOD,
ecumenists who are desperate to have a "saint"
I have seen even those in the OCA promote the veneration of Saint John Maximovich. Such a blanket condemnation as you said I don't think is entirely accurate. But in general I would tend to agree with you.
What I do not understand is what you said about Papa Nicholas Planas. My understanding is that he was one of the priests who served liturgy for the Old Calendarists in Greece before they had bishops.
