Brothers in God :
In the Gospels, Jesus calls himself a human being, a man. "But now you seek to kill me, a man who has told you the truth which I heard from God" (1) Lidden writes "The Son of Man, as applied to himself by Jesus, doubtless expresses a real humanity, a perfect and penetrating community of nature and feeling with the lot of human kind." Jesus used the phrase, "the Son of Man", to emphasize his own humanity. He said "the Son of Man has nowhere to lay his head." (2). He called himself, "the Son of Man" for a particular reason because he considered himself to be truly human.
Jesus said that he was God. The High Priest at his trial asked him, "Are you the Christ, the Son of the Blessed One?" Jesus in reply used the God-name which had such a profound effect on other people, "I am," said Jesus. "And you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven. "At this the High Priest tore his clothes and said "you have heard the blasphemy."" (3.)
The High Priest no doubt would have been reminded of the encounter between Moses and God in which Moses asked him what his name was. We read "God said to Moses, "I AM WHO I AM. This is what you are to say to the Israelites: "I AM has sent me to you.""(4) Jesus angered the crowd so that they picked up stones to throw at him with another claim to deity when he said, "I and the Father are one." (5)
Why did the "I am" name have such a profound effect on people?
