You haven't specified any particular denomination, so I'll stick with a view that is Biblical without any later doctrinal additions.

That there is "no need for the idea of the trinity", is fine. Certainly the original Apostles had no such concept. It is sufficient for Christianity that the Son and the Father exist.

What the being we know as the Son did, was to completely empty himself of all divinity and become a fully human being. As such, he was subject to the same temptations as anyone else, and would have become subject to the eternal death penalty if he ever sinned. Jesus "was in all points tempted like as we are, yet without sin." (Hebrews 4:15).

This is a key point that many Christians fail to understand when they quote John 3:16 "For God so loved the world, that he gave his only begotten Son".

If it were certain that as a human being Jesus would never sin, and that as a result he would be resurrected back to his fully divine spiritual self, then there really wasn't much of a sacrifice. And Jesus's temptation in the desert etc. would have been nothing more than symbolic rituals.

But this wasn't certain. The great sacrifice was that Jesus could have sinned; that had he done so, he would have died and stayed that way. He would no longer exist, and God the Father would be left alone for all eternity.

This is the central key to what Christianity is all about. The life of a spirit being that had existed for eternity was contingent upon the ability of a single human being to live a life without sin. That is what the Father's sacrifice was. That is what "so loved the world" really means.

EDIT: I wonder why this is generating negative votes. Is there something fundamentally wrong with what it says, or are people downvoting simply because it conflicts with their own beliefs about Christianity?
