I think it all skates a very fine line: I'm not into very specific discussion, for a raft of reasons that resemble a small continent in size.
But I don't care about affiliation - you could be a Christian, a Pagan or a Mormon AFAIC - just so long as you keep the minutiae of your beliefs in your back pocket here.
Stating you're into bible study is on the right side of the line, by my personal metric. But it's as on (and then over) that fine line as it gets, once you move from the general into any actual statements of any matters pertaining, whatsoever. Ditto worship music - it's not just
music, but it is
music. So the music part is fine, I believe. The why-ness of it less so, while on this chunk of (un)real estate, and posting at the pleasure of those that own it.
At that point, it becomes akin to discussing not
that you enjoy dancing while naked, but rather why you like dancing naked in the firelight on Beltane
You're basically pushing your luck, having flagged your specific context. And before anyone asks: no, I'm not into that either...
I got a temp ban on TGP, which I made into a perma-self-administered-ban by the simple expedient of not bothering to recognise my last warning. I got it because the mod in question couldn't tell the difference between a statement which he thought was about politics (which he knew was verboten), and one that was actually about economics and empirical data (which he didn't understand).
So yeah, fine lines.
