Having gone back and reread my original posting, I can see how it isn't very clear what I'm trying to get across.
I'm honestly not sure how to make it clear without writing a long paper. It's a bit difficult to lay the groundwork for such a broad and complex topic without significant interaction with both Orthodox and RC anthropology, theology, epistemology, etc.
Though I am most certainly not professionally trained, a professional philosopher, or systematic in anyway (nor do I pretend to be): I'm not completely in the dark on this stuff (born and raised Orthodox, grew up in a heavy Catholic culture, Catholic school, mt first BA is in Classical studies, I've read a decent amount of ante-nicene/nicene Fathers throughout the years, etc). I've also spent a lot of time debating and arguing against the uses abuses of reason, but I do this on secular reasoning and grounds with secular methodology and anecdotes*. I don't see anything wrong with that. Reason is an attribute of man, and it is an unavoidable feature on being human...in the same way as it can form cities and perform acts of mercy it can also destroy cities and perform acts of cruelty.
If your "quickie" response is something along the lines of: True Theology is a Holy, prayerful, ascetic and moral practice, I agree. I'm not certain how big the gulf is between Catholicism and Orthodoxy is on this, as I've heard several different answers though I agree that Catholics tend to really a bit more heavily on an articulate kind of rationalism. I guess I just don't think using Aristotle in a proscriptive classic and dead language like Greek or Latin is the worst thing in the world when it comes to that kind of thing if one has to use a formal and precise language among more academic theologians.
Anyway, that's kind of why I asked for a paper, lecture, source...just so I could see where you were coming from. This may be a big subject, so if you want to drop it that's fine. I was just curious.
*My favorite line of thought is using my job: I'm a Medic, which means I am a tradesmen and I put into use the life sciences which contrast heavily with a subject like engineering and physics. And the practice of a trade utilizing a larger, potentially infinitely complex body of knowledge (the life sciences study more complex phenomena than the engineer or the physicist) is going to frustrate many rationalists and "irrationalists" alike.
