1- He said they didn't KNOW Him.
2-Same thing.
3-Again, in the originals there LIKELY was something to denote the name, since it didn't EXIST in that language. Likely Hebrew, as in the first Septuagints. All we have are later copies, the earliest being tiny fragments BELIEVED to be a little less than a century later.
4- ASSuming is a sad thing to do.
5-They emphasised that it is the Name that was GIVEN by the True God- thus Christ IS the one to be highlighted.
AND-
6- You offend him with such antichristian dogma, for-
Ex 3:14- And God said unto Moses, I AM THAT I AM: and he said,
Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.
15- And God said moreover unto Moses, Thus shalt thou say unto the children
of Israel,
Jehovah,
the God of your fathers, the God of Abraham, the God of
Isaac, and the God of Jacob, hath sent me unto you:
this is my name FOREVER,
and this is my memorial unto all generations.
Neither Judiasm, Koine Greek, nor the foul Trinity Dogma can change that.
FINALLY, the Name "Jesus" in Hebrew means "the Salvation of JEHOVAH"!
