How readesth thou ?
Deuteronomy 6:4King James Version (KJV)
4 Hear, O Israel: The Lord our God is one Lord:
I agree...
Jesus had an interesting conversation with a Scribe which is relevant to this thread.
Mark 12:28-34 (New American Standard Bible)
28One of the scribes came and heard them arguing, and recognizing that He had answered them well, asked Him, "What commandment is the foremost of all?"
29Jesus answered, "The foremost is, 'HEAR, O ISRAEL! THE LORD OUR GOD IS ONE LORD;
30AND YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND, AND WITH ALL YOUR STRENGTH.'
31"The second is this, 'YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.' There is no other commandment greater than these."
32The scribe said to Him, "Right, Teacher; You have truly stated that HE IS ONE, AND THERE IS NO ONE ELSE BESIDES HIM;
33AND TO LOVE HIM WITH ALL THE HEART AND WITH ALL THE UNDERSTANDING AND WITH ALL THE STRENGTH, AND TO LOVE ONE'S NEIGHBOR AS HIMSELF, is much more than all burnt offerings and sacrifices." 34When Jesus saw that he had answered intelligently, He said to him, "You are not far from the kingdom of God." After that, no one would venture to ask Him any more questions.
The question that you have to ask is.....
What was the Scribe's understanding of the nature of God? I think that it is obvious that the Scribe believed ""HE IS ONE, AND THERE IS NO ONE ELSE BESIDES HIM; ""[Deut 4:35]
Jesus concurs with the Scribe's assessment when he ""saw that he had answered intelligently"" and Jesus said...."You are not far from the kingdom of God."
IMO Jesus affirmed that God is one and one alone and there is no other God.
