I think we need to remember that our church leaders are, well, sinners and human beings like the rest of us. I met Met. Jonah when I spent Pasca at his monastery about 5 years ago. I wonder if maybe he should have stayed being the abbot there, because it was clearly evident that his heart and soul had been poured into creating the monastery in Manton. There is a talk by Met. Jonah available as a podcast to download online where he talks about his spiritual journey to building the monastery in Manton. It is a wonderful monastery and maintains excellent relations not only with the Plantina monastery nearby. Two monasteries that are completely filled with American (and a few Canadian!) monks. Sure, it doesn't have the million dollar chapels and temples of St. Antony's or other Greek monasteries.
Met. Jonah wants to see Orthodoxy more accessible to genuine seekers, like he himself was as a young man. I think he is tired of the "nave behind the plexiglass", as it is at St. Anthony's monastery, by the way literally, but exists quite metaphorically at the completely ethnic parishes. He has a powerful and very genuine ideal of an American Orthodox Church. I frankly see nothing wrong with that. United we stand, divided we fall.
There are some "melting pot" churches out there, where people are all united by being Orthodox and not about what country their grandparents or great-grandparents were born. My former church in Salt Lake had a convert priest, a cradle Orthodox deacon, and a Russian reader who was still learning English. About 70% of the liturgy being done in English, and then a decent representation of other languages. But, that isn't the point. The point is being united in Christ. Didn't Paul warn about "divisions among you"? "I belong to Serbian" "I belong to Greece" "I belong to Fr. Epariam of St. Antony's monastery" etc, etc.
We need to be truly united in Christ. And, so many Orthodox in the United States feel excluded, or, worse, only included when they are at their ethnic church. The relations between the Orthodox Churches in any city are SO important. How can we even attempt dialogging with heterodox when we won't engage in discussions among ourselves? Why is Greek the exclusive language used liturgically at Holy Cross, where 95% of the student don't speak Greek? What is up with Russian and Serbian language schools at churches? It seems to me that at church, the focus should be on the Tradition of the Church, be it the Bible of Lives of the Saints or patristics or history or whatever.
I've gone off topic a bit: but, I really think that Met. Jonah could be the first in a line of newly minded bishops that want genuine unity among the canonical churches. The main point Fr. Jonah made in his wonderful podcast lecture is the problem of Orthodox Christians in big, culturally diverse cities exercising tribalism instead of worshiping Christ. In Russia, people go to the church that is closest to their house. That is just what they do. Here in the States, our individualist nature (which is COMPLETELY at odds with Orthodoxy - but, that is another topic) has people who won't go to a certain church because the priest might have a short beard or the church has pews or other reasons it is not "Orthodox" enough.
This is a very complex topic with no simple solution because Orthodoxy is and always has been a religion that tended to be along ethnic lines for its entire history. The Byzantines were Greek, and when the Bulgarians became Orthodox, their was no question of Bulgarians going to a church where Greek was spoken. Russians could count on Church Slavonic in all their churches, and that everyone spoke Russian!
I think that Met. Jonah is one of the first primates to really address in detail this problem in the United States, and to think about how to develop a genuine "American Orthodox Church." But...it is going to be an uphill battle to say the least!
