Obviously nobody can know 'private thoughts'. (Ron D)

Exactly - so you don't know for sure which composers believed in God, only what they said.

This poster also, it seems, needs a course in reading English. I've said more than once that it bothers me not in the least if an atheist writes a Christian piece, as long as the composer is respectful of the tradition.

Patronising though it is, that isn't the point I was addressing.

By the way, I'd be curious to know the poster's own view on Mussourgsky and Baba Yaga.

The point of my comment was that I haven't a clue whether he believed in Baba Yaga and neither do you - but I do know you don't spell Mussorgsky like that.
