But even this doesn't really answer the question.Marsh said:Jesus said that he is one with the Father.
So beleivers are (or will be) "in" God, in the same way that Jesus is "in" God.John 17:20-21 said:"I do not ask on behalf of these alone, but for those also who believe in Me through their word; that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us
This phrase is a reference to the vision of Ezekiel (Ez 1:26) In modern translations, the term is usually translated "one in human form" or something like that. Originally, that's all that "son of man" meant: a human being. Around the time of Jesus, there was a lot of interest in, and speculation about, visions like that of Ezekiel and what they might mean. Other Jewish writings of the time also use "son of man" to refer to an exalted being, sometimes sitting on a throne. The books of Enoch, for example. Interestingly, the book of Jude in the NT quotes from Enoch (Jude1:14-15).BluejayWay said:What did he mean by this phrse, as opposed to the "Son of God"?
As has been mentioned already, "son of God" could be used for a king of Israel, or for the Jewish people as a whole. We could sum it up by saying:
"son of God" = chosen one
"son of man" = exalted one
In Christianity, of course, both of these terms, as well as others like Lord and Christ (Greek for Messiah = "anointed one") and Logos (=Word, reason) came to be terms for Jesus.
If you put the NT books into chronological order, you can see some of the development of ideas about Jesus.
(Hypothetical) Q document: Doesn't use any of these terms, seems to consider Jesus as a human teacher.
Paul: Jesus is Lord and Christ. The Messiah was not necessarily a heavenly being, rather it was expected that a human, a descendant of David, would arise and become King. "Lord", too, could refer to a human in authority, even as in English (e.g. House of Lords in British Parliament).
Mark (earliest gospel): Jesus is called Christ only in a few places. Mostly, Mark uses "son of man".
Luke and Matthew: Jesus gains a miraculous birth and appears after his death in exalted form.
John: Jesus is now "one with God" and has become the medium of salvation and a pre-existent being.
