I think a lot of Russians today like Father Seraphim because he became "Russianized," in that he learned the language, culture, etc. Most Russians today do not care about Orthodoxy, they only care for preserving their nation. It is their desire to see all Americans become Russianized like Father Seraphim. I believe the greatest veneration of Father Seraphim comes from people in the MP. That doesn't say alot.
And I have seen people on this website call the schismatic Matthew a saint. Newsflash: people do NOT decide who is a saint. God does.
I have read everything about Father Seraphim and read many of his own books. I have never seen any evidence he is a saint. Now, if he is incorrupt today this would change my perspective. I'm open minded.
