No, not really. Some of the best music ever written was written for the Christian liturgy. I have been a professional musician in my life, and have played many such pieces. It's only natural that I would enjoy hearing them in the setting for which they were written.
I speak Russian, albeit haltingly now, so it is very interesting to hear Church Slavonic, a predecessor to the Russian language. It's kind of like listening to Latin, the predecessor of all the romance languages.
Agreed, Russian Church music is some of the most beautiful in the world.
