I don't understand Russian, but it would be interesting to hear what you think of the Greek-to-Russian translation. If I'm right about it, this will go through English and the result will make it obvious. However, since I don't know Russian I don't really know what to expect.
Sub par quality of the translation is evident even with no understanding of the source. But to be fair I understood even less of the Greek text, when I tried to use online dictionaries.
