Indeed my christian friends mentioned the exact thing when I introduced them to bitcoin, and they were very excited about the system because of the bible's prediction of one currency and it seems destined to happen. Personally I think it's a great thing to get the religious motivated as they have a very large and widespread network and it's a great way to spread bitcoin to a larger audience.
I like it! Hashin fer Jesus - find a block fer God. Hallelujah! If you can get the moral majority to love Bitcoin you got it made. Throw in some apple pie and a baseball game and let's wrap this shit up!
