Concilliar Press prints a lot of the pamphlets and small booklets found in many Orthodox churches
Yes, I would agree. In addition, a lot of their pamphlets are put out by those associated with the former Evangelical Orthodox, so they know the talk of your target audience from the inside.
I remember a criticism of the Orthodox Study Bible, that it was too "Protestant," talking about topics that the Orthodox don't dwell on, like justification. This criticism 1) presumes that the Orthodox in America know Orthodoxy (a big presumption) 2) ignores that we live among, and are influenced by (read: converted children) a Protestant majority 3) has no vision of outreach (read: evangelization) to that Protestant majority.
God bless your endervors with much fruit!
