HMMMmmm...
Matthew 1:21
She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.
This wasn't an instruction to the general public on how to address the Lord in communication.
On sharing this information I didn't try to assert the correct way to address Lord, but to show the Russian Christians' cultural habits. The British having met their Queen wouldn't tell her: 'How you doin' Betty?' for the same reason.
That's a reason why the direct translation of an American sermon can be received coldly in Russia.
