...Thanks, for the explaination. My apologies for any ignorance or disrespect...
No disrespect! I ask dumb questions on threads about Christian stuff all the time... I'd rather learn something than continue to be ignorant, though, and you asked in the same spirit.
My most recent dumb question - I asked after attending a wedding at a Catholic church. I asked what the fold-down knee pads in front of the seats were for. :) I had never been inside a Catholic church before.
