Just to play DA here, isn't this semantics? People are recorded as saying "Praise Jah". Jah a shortened form of the divine name pretty much without dispute. Use that if you want. Our cultural imprints regarding what we do and do not call our own parents mean very little here. Why can't you have the option to do all of the above?
I think there is a decent case for "Jehovah", about as much as anything else. Nothing can be stated with certainty, other than a superstitious reverence for the name led scribed to alter it a long time ago, so that we know very little as a certainly. But it does appear thousands of times. To argue it in and of itself has no validity or isn't something to even try to be known, I think is not intellectually honest. I think it harms the Trinity doctrine a bit and that might be why these arguements surface.
ALl of this is of course only meaningful if you even believe in the scriptures to begin with. I am finding myself less inclined to believe the bible is a book different than any other sacred scriptural text. I think the Hindu Vedas are much older than the bible no?
