Lord Jesus, son of God, have mercy on me, a sinner.

Turns out the translation is "Lord Jesus, Son of God, have mercy on me a sinner." Who knew that Trump spoke Russian?

Alas, I cannot read Russian, and it won't let me cut / paste into a translator. So I cannot help. I can only suggest, check their website.

I only speak English, sorry, the cathedral is near Central park & Columbia University
