I don't know if only I myself have this concern, but I am not convinced the American population is one capable of guiding ourselves in any profoundly Orthodox manner. I myself am relieved the ancient Sees continue to have a guiding presence here.
Not to be polemical, and the example is too slight to bear the lesson I want to make out of it, but let me hold up this paragraph for some observation:
As such, we ask our brothers of the Assembly to consider a broader question: For what purpose has God, in His infinite Wisdom and Providence, brought us together in this country? Is our answer a positive response to the Lord’s commandment to “preach the Gospel to every creature”? Is our answer to look to the model provided St. Tikhon at the turn of the last century, and to “share our spiritual wealth … with others who are deprived of these blessings”? In His High Priestly Prayer in St. John’s Gospel, our Lord Jesus Christ prays to the Father and asks that “they may be one, as we are”. How is this to be realized if we place limits on our responsibility to be the One Holy Catholic and Apostolic Church? St. Paul tells the Galatians that “There is neither Jew nor Greek ... for you are all one in Christ Jesus” [Gal. 3:28] Does this not direct us to see no difference between the immigrant from Russia and the one from Indonesia, between the one from Africa and the one from Central America? Does this not direct us to see the Agnostic, the Protestant, the Buddhist or Taoist in the same way we see the marginal Orthodox Christian?
Could this be imagined in the mouth of, say, St. John Chrysostom, or even St. John of Kronstadt? Whether or not, one can certainly imagine it in the mouths of most American denominational conferences.
There is also the compounding concern that, as a rule, when America gains control of enough of a portion of anything, she tends soon to control it, at least to an outsize extent, worldwide.
In short, at least I myself am more concerned about salvation than about American face and influence. Indeed, if that weren't true, I'd have found some well-positioned Protestant sect to join.
