Nevertheless, Agabus, I think that you have hit upon a key problem with Orthodox in small rural areas who want to establish mission parishes: Where do they find priests?
In the lower 48 US states, we have 3-4 major seminaries. All are very expensive, and they take years to obtain an MDiv degree. They are located in either New York, New Jersey or Pennsylvania, all states with high costs of living expenses. There are no major seminaries in the lower 48 states outside of the East Coast. Since Orthodox Christianity does not allow priests to marry after ordination, many men are unwilling to consider the priesthood until after they are married, have kids, and then what? They are established in their careers and the prospect of seminary would represent a major disruption for their families. And assuming they go, graduate and are ordained...many will walk out with hefty student loan bills.
So few of these student loan-laden priests are going to want to taken on a small mission parish of 20 souls who cannot materially support them. And who could blame them? Why should they want to do this when there aren't exactly a plethora of priests available to serve large churches in urban areas?
The end result is that Orthodox churches are hobbled or handicapped, from a tactical/logistical standpoint, in starting mission churches when compared with Baptist/Pentacostal/Nondenominational churches were any guy with a Bible and a loud voice can start a church.
Now in Greece, as I understand, the situation is entirely different. There are priests with MDiv degrees, like in the US. These tend to live in large metropolitan areas. But in small rural areas, there is a different system, that of the village priest. If you live in, say, a remote fishing village, then the village priest is a part-time priest, and he holds an inherited position. He is a priest, like his father, grandfather, etc. He is a fisherman most of the day, because the money he receives from being a priest would never support his family. As for his priestly duties, he receives a small stipend from the Greek government. Additionally, he charges fairly substantial fees from his fellow villagers when they come to him for marriages and burials (and those villagers probably resent him deeply for this). Be that as it may, he is present every Sunday to officiate the Divine Liturgy and other services in a small village that would never have enough people to afford a priest otherwise.
Now I'm not saying this is a perfect system - it has its disadvantages like we have other disadvantages with the seminary system established in the US. But it seems to me that the Orthodox churches in the US could/should come up with some sort of "village priest" type model for small groups in out-of-the-way places who want to start churches. Perhaps, in such a system, men in the rural US with some theological learning and desire could be ordained on some sort of provisional basis. These men could obtain needed liturgical and theological training through some sort of distance education program, (coupled with frequent guidance from their local bishop or his representative, of course).
Creating a village priest system would not be a perfect solution, but it could be a way to get rural parishes up and running which would not otherwise be able to afford seminary-educated priests for years or decades. I'm guessing that part of the success of Gillquist's Evangelical Orthodox Church in the 1970s-80s was that no one could tell him not to ordain so many men on a rapid basis.
