Baloney. In order for something to be estsblished by a statement in the passage said statement must be stated in the passage. The unity of God is nowhere stated in the passage we are discussing. Case closed.
You need to read again.
Joh 6:41 The Jews then murmured at him, because he said, I am the bread which came down from heaven.
Joh 6:42 And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven?
Joh 6:43 Jesus therefore answered and said unto them, Murmur not among yourselves.
Joh 6:44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
I can read. I know what it says. I've been reading for many years. You are obviously mistaken. Jesus was specfically dealing with His position with the Father.
