Are you Orthodox? It was my understanding that Orthodox Christians have the same understanding of the nature of the Trinity and of Jesus as do the Catholics. That is, the Trinity is three persons in one nature. Jesus, believed to be fully God and fully man, is one person with two natures: a human nature and a divine nature (the 'hypostatic union'). The word used in the Council of Nicaea is homoousion, meaning "same essence", thus the "one in being with the Father" of the Nicene Creed. According to Orthodox Christology, you cannot separate the human person of Jesus from the divine second person of the trinity. Orthodox Christians do not believe that merely the body of Jesus died on the cross. When Jesus, as they teach, became incarnated, GOD became MAN. You cannot discount the human body of Jesus as having nothing to do with God; according to Orthodox doctrine, it has everything to do with God.
By the way, if you are a Jew, tell us how Judaism regards Jesus.
Yes, I am a Jew, and a traditional Jew at that, not a messianic one. Jews believe that Jesus was a man, a charismatic preacher, but not divine, and not the messiah. Jews believe that the messiah will be just a man, not divine or even necessarily a miracle worker. Within his lifetime, he will fulfill all of the messianic prophecies of the Hebrew scriptures. Jesus did not do so, which is why Christians teach of a second coming of Jesus, at which time they believe he will fulfill the prophecies he did not meet the first time around. There is nothing in the Hebrew scriptures which prophecies a second coming of the messiah.
"Charismatic preacher" I suspect is not the whole truth. It's like saying that Zhirinovsky is a "charismatic politician" when one really means "mad clown". Do Jews regard Christianity as heresy and Jesus' teachings as false?
