Ahh... but there were concelebrations with the Serbs during the 70's, of which Fr. Seraphim Rose talked about; there are statements (even from the 60's) in which it can be shown that the ROCOR hierachs didn't deny the grace in world Orthodoxy, ROCOR clergy and bishops (including St. John, from what Fr. Alexander Lebedeff says) were giving communion to new calendarists, and there are of course other things... I'm sure we could swap quotes and historical examples/happenings all day, much like Protestants do with scriptures! (I say this to my own shame, not directed at you)
But, regarding the anathema, here's what Archbishop Vitaly said in 1984:
By proclaiming this anathema, we have protected our flock from this apocalyptic temptation and, at the same time, have reluctantly put before the conscience of all the local Churches a serious issue, which sooner or later they must resolve in one way or the other. The future spiritual fate of the universal Orthodox Church depends on the resolution of this problem. The anathema we have proclaimed is de jure a manifestation of a purely local character of the Russian Church Abroad, but de facto it has immense significance for the history of the universal Church, for ecumenism is a heresy on a universal scale.
Just about everything I've read on the anathema says roughly what the above says: that the entire world had better pay attention to what was going on, that ROCOR was trying to sound a wake up call, but that the anathema, in itself, had a purely local character: that it effected only those within ROCOR; and I might add, it effected them only after an ecclesiastical trial: the anathema was a canon or law or guideline, not a condemnation or verdict. It is perhaps true that the anathema is plain regarding what it speaks of, but it is also plain that not just anyone and everyone, not even a bishop or archibishop by himself, has the right to use the anathema to condemn someone else. Because of the history of ROCOR, because of all the breaks in union and reformations and so forth (much like the East in general), she's always been very conciliar-oriented. One bishop does not have the power to go off on his own, shooting from the hip at those heretics he perceives.
I can understand Peter's point. If heresy is heresy, and should be condemned outright; and if ROCOR was ok back then but has slidden down the hill into ecumenism and apostasy now; then surely it can be shown from the official ROCOR statements that they denied the grace of world Orthodoxy, refused all communion with new calendarists, etc. back in the 60's? If this can't be done--when it's admitted that such statements are not made in the "official" documents, then one has to ask: why not? If ROCOR was Orthodox back then, and you must break communion with heretics to be Orthodox, then why would ROCOR be so hesistant to officially (another word for "publically and authoritatively") say the things that the TOC says they believed? Are there epistles from the synod talking about cessation of all relations with (what we might today call) world Orthodoxy? If not, why not?
EDIT-- And no, I'm not getting hung up on being "official," but think of it this way. Let's say that certain members of a football team said that they were getting a new star player. They refused to issue a press release or hold a press conference on the matter, they refused to include his name on the roster given to the public, they refused to put his name in the team literature being printed for the season, etc. Yet some people keep insisting "he's coming!". Well... it might very well be the convinced opinion of those people that he's coming, but if so, then why won't the team acknowledge it to everyone? This guy is a star: it'd be the type of thing you'd think they would make very explicit and talk about openly, yet they don't. The same goes with the ROCOR situation, IMO. If ROCOR did do what you say they did, then why didn't they say they were doing it in their official documents? What does that reluctance to say things openly and publically signify?
