I don't know what this means
You'd have to know Christian history. The Docestists (and some 2nd century Gnostics) believed Christ only 'appeared' to be human, by was in fact some kind of spiritual/angelic being.
Do you mean that the soul of Jesus is G-d? If so, then that would mean that G-d is a soul which I find very confusing indeed...
I'm, not surprised. The theology of the Incarnation is quite precise.
There is a creed of Chalcedon, the council called to discuss and give a definitive teaching on the nature of the Son:
We, then, following the holy Fathers, all with one consent, teach men to confess one and the same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a reasonable soul and body; consubstantial with us according to the manhood; in all things like unto us, without sin; begotten before all ages of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the virgin Mary, the mother of God, according to the manhood; one and the same Christ, Son, Lord, Only-begotten, to be acknowledged in two natures, inconfusedly, unchangeably, indivisibly, inseparably; the distinction of natures being by no means taken away by the union, but rather the property of each nature being preserved, and concurring in one Person and one Subsistence, not parted or divided into two persons, but one and the same Son, and only begotten, God the Word, the Lord Jesus Christ, as the prophets from the beginning have declared concerning him, and the Lord Jesus Christ himself taught us, and the Creed of the holy Fathers has handed down to us.
I thought that I'd made it quite clear that I think that G-d wants us to convey truth to others and establish peace.
Well that's Christ's message, in a nutshell.
If G-d manifested as a human being, then we couldn't say for sure which humans out of billions could be G-d. Why G-d would want to do that beats me!
Well, that's the problem of faith, isn't it?
I mean, what's to stop anyone saying he or she's been given a revelation by an angel? How many prophets have popped up since Mohammed (pbuh) with the next latest revelation?
Nevertheless, putting the issue of divinity of humans aside, we still have to discern which humans are messengers of G-d and which aren't. Same sort of thing, I suppose.
Yup.
