I’m not sure we can use geography as a measuring stick for truth, though? Orthodoxy is NOT very accessible where I am. I have to drive about 45 minutes. I’m not happy about that. But when I get there I am wowed at the beauty and truth of the liturgy as well as its lack of innovation and pandering to modernity. I don’t see a wiff of protestantism in it at all. Plus the Orthodox tend to make more sense to me.
As far as doctrinal development, the Orthodox seem to me to represent the classic maxim “if it ain’t broke, don’t fix it.” And when it does need fixin’ you hold a council and do things holistically, not depending on a few scholastics to innovate. And there have been few times in which a council has even been needed since the Schism, which is a testimony to the goodness and complete nature of Orthodoxy. Orthodoxy hasn’t had a Reformation. I think that is telling. If the Church doesn’t theologically innovate, no need for a reaction to the reaction of those heretics from within because you won’t have heretics!
As far as Eucharistic Ecclesiology, that is more historically the approach and praxis of the ancient Church from what I’ve read, especially in Meyendorff’s works.
Promoting intellectual growth, is that the purpose of the Christian religion? I am truly asking myself that. Faith, marveling at the divine mysteries, theosis, the journey, they all trump intellect.
