we have a JST of exodus chapter 6:3, and abraham 1:16 that say Jehovah was revealed to abraham. as for the emmanual, it's like where they say he will be known as the prince of peace etc. it doesnt mean his name is going to be Jesus Emmanuel prince of peace...Christ. he is known by many names. And an angel gave the name to Mary. it was obviously known to them (angels, God, Jesus) a long time. plus, a lot of the book of mormon is abridged, and therefore the plates calling christ as such may have been edited in that the name is made to Jesus Christ from jehovah etc. i don't honestly know.
and i take back the part about me saying Christ has always been. i realise that was a mistake. Even Revelations shows Christ's birth (revelations 12)
(edited as it was a bit vague) (er)
Your Joseph Smith translation is wrong. First off, Jehovah is a poor translation of the name YHWH. Secondly, that translation goes against every other translation ever made. Even ask a jew, with their pure hebrew copies how it translates.
And the entire book of Abraham was proven false by egyptologists again and again.
Matt 1:21 And she shall bring forth a son, and tou shalt call his name JESUS: for he shall save his people from their sins.
Now, ignoring the fact that this doesn't match what the jewish messiah was supposed to do, this was the first mention ever of Christ's mortal name. Now, if Jehovah was the name of christ in the pre-mortal realm (which is true, according to Mormon beleif), then why was he throwing the name "Jesus Christ" around? First off, his name was Yeshuah, son of Yoseph, not Jesus Christ...
Argh, NONE OF IT MAKES SENSE!
