Dear Friend,
The issues are really more to do with politics than religion or culture (including the Old Calendar). But you have researched these matters well.
And St Philaret of New York City was born Orthodox so he did not “reject” papal authority as someone who had earlier maintained it.
There is no reason why he could not be venerated as a saint by all, even though he has only been canonized by one local Russian group and is not recognized as a saint among the ROC in general.

Alex, I don’t disagree with you. In fact I wanted to post my observations about “politics” as it influences the relations of Moscow, not only with Rome, but even with Constantinople! But somehow my post about the Calendar, pews, musical instruments, and other “smaller stuff” turned out to be like a small treatise in itself, with no room left for mentioning “politics” within the 6000-character limit!
Also, my choice of the word “rejected” in conjunction with St. Philaret wasn’t the best. Indeed, he wasn’t a Catholic who rejected the Pope, and became EO. St. Philaret was born in EO Russia, baptized and raised EO since childhood. He simply defended Orthodoxy as he knew it, against such things as “Papal authority”, “ecumenism”, and so on, because he was essentially raised in an Orthodox Church and tradition which taught him that “universal Papal authority” and “ecumenism” are heresies. I guess the same observation would be true with essentially all canonized Russian EO saints, because they were all raised and steeped in the tradition and teachings of the Russian EOC, which taught for centuries that the Catholic Church has fallen victim to errors and heresies.
I do venerate such Russian EO saints as St. John Maximovitch, St. Seraphim of Sarov, St. Herman of Alaska, St. Peter the Aleut, and St. Innocent of the Kuryli and Aleuti Islands. I will add St. Philaret to this list. I venerate them for their sanctity of life, while I also believe that their theological beliefs were fraught with errors.
OK, regarding “politics”, first of all I want to mention that as far as I know, Moscow has extremely tense relations not only with Rome, but also with Constantinople. It really has to do with the struggle for leadership of world Orthodoxy and world Christianity. They obviously believe that First Rome is in heresy and unfit to lead Christendom, but they also contest the claim of Second Rome (Constantinople) as being “moral leader”, “spiritual leader” of World Orthodoxy. Hence, Moscow calls itself Third Rome, and aspires to gain recognition as the leader of World Orthodoxy. I remember reading an interview with some high ranking Russian clergyman (I think it was Metropolitan Kyrill of Smolensk, before he became Moscow Patriarch), who very eloquently made the point that Moscow has 90-150 million faithful, while Constantinople has 3000-5000. And he made it clear that Moscow aspires to be recognized as the real leader of World Orthodoxy, instead of Constantinople who presently claims this title.
Still, I wonder why is Constantinople in much better terms with Rome, than Moscow? Why did Constantinople agree to lift the mutual anathemas, why do the Patriarchs of Constantinople regularly visit Rome and have the Pope as their guests visiting Constantinople, and why is Moscow essentially the opposite of all that Constantinople stands for?

I mean, the 4th Crusade sacked Constantinople, it didn’t sack Moscow. And yet, Constantinople knows how to forgive and forget, while Moscow holds some sort of grudge against Rome. For example, Moscow was outraged when in 2002 Pope John Paul II reorganized the structure of the Catholic Church in Russia, and established 2 new dioceses, bringing the total number of dioceses to 4. All the while, Moscow freely establishes dioceses in Catholic Italy, Austria, France, Spain, and so on, and Rome doesn’t throw hissy fits like Moscow did in 2002.
