The Fourth Proof
The fourth indication that disproves the notion that Jesus is God is the fact that Jesus himself said things that prove he was human and of human origin:
•    Jesus said of himself: “The Son of Man came not to destroy souls.” [Luke 9:56,Douay-Rheims]
This text clearly states that Jesus is not the son of God; rather he is the son of man, who is a human being.
It is well-known that he was the son of Mary, who carried him in her womb until she gave birth to him as all women give birth to their children.
•    So Jesus said, “When you have lifted up the Son of Man, then you will know that I am he and that I do nothing on my own but speak just what the Father has taught me.” [John 8:28]
Does this text not clearly indicate that Jesus was human?
If Jesus were God, he would not have described himself as human by calling himself “the Son of Man.”He would not have said, “I do nothing on my own”, because the Lord of the universe does all things and controls the affairs of the entire universe. Based on that, it is not rationally possible that Jesus could have said, “I do nothing on my own,” while at the same time being the Lord of the universe; otherwise, he would have been speaking deceitfully – and far be it from him to do such a thing.
•    Jesus said of himself, speaking to a crowd: “The Son of Man came eating and drinking.” [Matthew 11:19]
•    Jesus said to those who wanted to kill him:“As it is, you are looking for a way to kill me, a man who has told you the truth that I heard from God. Abraham did not do such things.” [John 8:40]
•    It was said to Jesus, “You are the son of God,” and at the end of his response to that, he called himself the Son of Man. See John1:49-51.
•    In the Gospels, there are other verses that call Jesus the Son of Man; see Luke 17:22 and 18:8, Matthew 12:32.
The fact that Jesus repeatedly and explicitly described himself as being human and “the Son of Man” clearly indicates that he was indeed human. It is not possible, in the case of one who said such words, that the thought could cross his mind that he was God or the son of God, or that he came down to earth to call people to worship him; otherwise, he would be someone who was trying to deceive people – and far be it from Jesus to do such a thing.
From these texts, it becomes clear that the notion that Jesus is God is entirely false, and that the truth which is established in the Gospels is that he was human.
