Real strange question, I know, but yet...
So I've looked up the name Castiel, because I was curious where they got all the names from (uriEL, castiEL, gabriEL, etc.) So I found out that Castiel means; My cover is God.
What do they mean with; "my cover is God"?
Does the "cover" means like shield, a blanket, или what? I'm really curious so... ah well thanks anyways :)
