Ah, but there is something that has not yet been discussed here, and that is blasphemy -- or, rather, the use of religious things, themes, ideas in ways that are hardly religious.

"Close the door! Were you born in a barn?" "As a matter of fact, yes. There was a star in the East, shepherds, angels...."

"Jesus Fucking Christ!"

"Christ on a [crutch, skateboard, surfboard, crouton, etc.]!"

"Holy Mother Mary Shit!"

"God's Blood!"

Blasphemy was, for many years and to an extent still is, a definitely Catholic thing. Protestants had sex and scatology.

Having grown up in a Catholic household and in the "Christian" tradition, I can't discuss this in relation to non-Christian religions, but I suspect they too have similar things.
