Logos,
I am always leary of discussions that speculate where the grace of God is. God will work where he wants to, he does not needs us to tell him where he should be.
I think you are misunderstanding, my friend. No one is trying to tell God where he should be, and no one is "speculating" (a very sensitive term to use in Orthodox discussions... it is perhaps for saints to speculate, not us sinners) "where God works". You have things backwards: it is not those in the Church who are "guessing" and "demanding," but it is God Himself who already told us through the Bible and the Fathers where his grace is, and we are only passing along what was taught. You are correct, God will indeed work where he wants to, and that includes outside the Church (otherwise I couldn't have become a part of the Church through conversion). Yet paradoxically, God also made some statements through his revelation to us about salvation, grace, etc. that seem to contradict this. I am thankful Fr. Serafim was able to articulate this. Remember, when we learn something from "tradition," that's the same thing as learning it from Christ's own mouth (since the Church is the human-divine body, and Christ is the head, leading it into the fullness of the truth).
