As I mentioned a couple weeks ago this is something I've heard for the very first time. Therefore I would have to, for myself and not protestants, say that it isn't a standard belief. I haven't given it the proper once over to yea or neigh it yet.
My interest in this topic caused me to notice it after a few years of daily bible reading. I'm sure the secrets in the Word have not all been discovered yet and are probably as infinite as the Universe.
