Yes, the title is an intentional Indiana Jones joke. Anyway, so I was reading the new book, 'Bearing Thorough Witness Etc.', and they mentioned an often-used doctrine in the Borg--the belief that Peter was given 3 keys to the Kingdom. I immediately paused when I read that and realized, hey, I've taken that for granted all this time. Who said how many keys Peter got? The Bible doesn't elaborate on its significance, does it?
So I'm turning to you folks and asking a pointed question: is this doctrine valid? I know of no scripture that specifies how many keys Peter got or what exactly that would even mean. Any thoughts on this?
