That seems about as good a definition as we shall get.
'Ethos' is a notoriously difficult thing to define, but in the context of the Orthodox Church an aophatic one is actually useful.
I have been to Greek Orthodox and Russian Orthodox services, and they are, in a sense, what it says on the tin; culturally they are 'foreign' to me. Those in search of another identity, or attracted to the exotic, may find this positively desirable and attractive; the rest of us won't. I shall never forget being told by one conver to Russian Orthodoxy that he had had to learn old church slavonic, so why was I not willing so to do. The answer was so obvious as to be hardly worth making, but I did, pointing out that if Sts. Cyril and Methodius had taken that line, it would have been koine Greek that he would have had to learn.
In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. (1 John 4:10)
