I quit the Orthodox-tradition list years ago because of the low-brow quality of much of the discussion. I would certainly be interested to read some of the statements that Fr Alexander provides, though, so please do provide them.
I recall that Fr John Shaw (now Bp Jerome) posted a few such statements some years ago, which did not strike me as really proving what he said they were saying, but I would be interested to read what Fr Alexander has dug up.
While I hope that I will enjoy as many years on the Earth as you have, I wouldn't guarantee that age produces moderation; after all, our saintly Archbishop Chrysostomos II is almost 90, and he has a rather strict position as far as I can tell...but I don't get agitated by such things at any rate. Facts are facts, and we have nothing to fear if we are seeking the truth. But at any rate, to me these statements of the Russian Church in the past on RC mysteries go right along with their refusal to baptize Roman Catholics; it was a policy that existed for some couple hundred years, but it was a mistake. It didn't invalidate them, but it has to be put in its proper historical position. Times have changed, the Roman Catholic Church has slid further into heresy since even a few hundred years ago, and the context then is quite different than Archbishop Hilarion's unfortunate (and in my opinion heretical) statements on RC sacraments now (which fit in to an ecumenistic model, which is a different model and framework than such statements in the past).
The bottom line to me is, we can drudge up all sorts of things from the past (times were certainly odd during the time of Eustratios Argenti; see the book with that title by Timothy Ware [now Met. Kallistos]), but we should be careful whenever we try to use such statements or practices to prove our current case now. I certainly think that applies to us Old Calendarists as well, to be fair.
