Eh, the problem with anecdotes is that they are by nature ephemeral.I think we should take a look at whether the decline of Orthodoxy is across ALL jurisdictions, or only certain jurisdictions. If it's all jurisdictions, why? And why is my anecdotal evidence so vastly different? I've attended a fair few different parishes (the majority of which have been Antiochian), and they've all been growing. Are these merely isolated incidents that I've been lucky to see?
And if it's only certain jurisdictions, why? What is going on in those jurisdictions that are causing people to leave?
I think this is a great example of how we must be very careful about how we think of Christianity. On top of all the other problems with the parish model as a whole, having a "presbyter-driven" community is a very dangerous thing, ripe for widespread spiritual abuse. Until the numbers of parishioners somehow reflect seriousness primarily about Jesus Christ—and not about liturgical attachments, programs, ethnicity, sentimentality, and seeking gurus and/or counseling—I'm not sure that the numbers are really that useful at all, even if they're collected with accurate polling.Eh, the problem with anecdotes is that they are by nature ephemeral.
For example, one parish that I am very familiar with had a dynamic, engaged and all-around good priest. The church grew significantly. When he left after approximately a decade of service, he was replaced by a guy who wasn't well suited to the parish (or, for that matter, the priesthood — he eventually flamed out and just left the office with a note of resignation one day); the church declined under him and then floundered significantly in the time after his departure. Now they have a priest of several years who is good with people and even has a bit of a (good) name in Internet Orthodoxy, and the parish has been growing again but with a different kind of folks than the first priest.
My point, I guess, is that a snapshot of the parish at any given time would tell you a pretty different story.
