In all my decades of studying within the faith never have I found anything high IQ about any of it; protestant, Orthodox, Catholic, etc. Lots of big words, tomes of wasted ink, and authoritative names though.
IMO this is a new challenge for the church though and one we're not addressing adequately. A lot of people are coming to EO because they are on some culture war RETVRN bullshit and considered us "based" or whatever. Priests often aren't effectively catechizing them and they still hold doctrinally evangelical beliefs completely foreign to the orthodox tradition.
And too many priests are naively subscribed to "any growth good growth," while a good handful of priests are openly aligning with the protestant far right and diving deep into culture war issues themselves.
It's good to see more young people in the church but the whole thing has me worried. I think there's a real possibility we become just another american christianity, compromised in the same ways, active for the same causes, but with icons and incense.
