That's a deep one, beamer.
Personally (and this is not a criticism, my friend). I've always considered religion and faith two separate entities. (Iknow "faith" doesn't appear in your poem) and I left the "man in the stole" a long time ago.
As far as religion being of "minimal cost". Not sure what you mean exactly, but those TV "Evangelists" make me think otherwise.
Again, this is just my reaction and is not meant as criticism, my friend. I like what you wrote and the way you wrote it.
Thank you for making me think a little today, beamer!

ETA: would the word "the" fit between "supposed" and "sin"?
