Jimmy Carter doesn't know that Jesus Christ is God. It was the preincarnate Jesus Christ who spoke to Moses:
(1) And the LORD spake unto Moses, saying, ... (13) If a man lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them. (Leviticus 20)
We know this because "no man has seen God (the Father) at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him" (John 1:18). Jesus Christ "is the image of the invisible God" (Colosians 1:18). Moses saw Jesus Christ in Exodus 33:23-23. It was Jesus Christ the LORD who spake all these words to Moses.
