Ok I was under the impression that the divine name was not in use shortly after captivity in Babylon because of superstition surrounding the name.
I have not done a thorough study of this subject as of yet. Just what I studied out of the Imperial Bible dictionary under the subject Jehovah.
To be honest I've only been at this study thing for a few months. I would like to know more about this subject of the personal name being used in the first century because that's a new thought.
I still hold however that the name Jehovah is grammatically inncorrect. Just because some guy a few hundred years ago made it up and it became accepted doesn't make it right. Further to address the supreme one of the universe by His first name takes some real balls. Father or Lord is more appropriate for us little specs here on earth.
(of course this is coming from someone who doesn't pray to God because I'm kinda pissed at him.π)
