Read my post again. I think I added to it some while you were responding. Your post doesn't make sense to me - He had to be perfect, to be the perfect sacrifice. Your answer is not scriptural, it's just human thinking and reasoning. Where did you get the idea that he has to be a sinner to take on the sins of the world? It's just the opposite. He had to be the perfect sacrifice.
I reasoned that if he were to take on the sins of the world he had to be human since humans are flesh and sinful according to scripture. If he were god/creator and the creator is without sin, taking on an incarnation doesn't make his nature any different. God's nature contradicts the nature of his incarnation if flesh=sin, so in that respect his son can't be his father.
When you sacrifice something it means you give up something for the well-fare of someone else. If christ were the creator he cannot give himself up because he cannot die. He can only sacrifice himself if he were able to die and since he cannot, I reason that he sent his "son" to do the job for him. Hense why he took on the responsibility I believe as a child or teen and always spoke of his father as a source of his father's (not christ's) edicts and message.
What's happening is when the disciples (and some christians) go to christ they think he is the creator because his father sent him to die for them. Christ says no, I am not the creator because the creator is bigger than I am.
Don't come to me as the creator come to me because I am the mediator between him and man.
The fleshly body the source took on was the mediator.
God loved mankind so much that he took on a fleshly body, lived a perfect life, then sacrificed that fleshly body for our sins, to show us how to live, and prove how much he loved us.
Trinitarians think God is 3 different persons, but he isn't. He was a Spirit that didn't have flesh and blood to sacrifice for our sins. So he made himself a body that could shed blood for our sins. The Spirit was the Father of that body, so he called it his Son. But it wasn't another person. It was the one and only God manifesting himself in a fleshly body. The Spirit was eternal and couldn't die, but the body was flesh and blood and could die.
Since flesh is sin you would be saying god took on sin which makes him a sinner (can't take on sin and be perfect at the same time).
Trinitarians say creator/savior/spirit are one most likely because they cannot see the difference-they are in one accord.
Christ couldn't give up something of value if he were perfect.
Personally, I'd rather christ be sinful insofar that if I were to "die in him" I (my flesh) can relate to him and when he sacrifices himself (per his father's wishes), I am as well.
If christ were perfect I would not be able to identify with him. It wouldn't be a sacrifice. But I know christians believe that he is perfect and a perfect person can sacrifice himself but that's not what sacrifice means. When you die for a person, you actually die-no longer here. If christ is the creator he cannot die so there is no sacrifice.
