I find it funny you would say this as you repudiate the incarnation in the work of the atonement.
I do not deny the necessity of the incarnation as a prerequiste for the possibility of atonement. I only deny the incarnation IS the atonement or INCLUSIVE in the atonement. The incarnation provides the appropriate body for sacrifice but it does not provide the righteous life to satisfy the righteousness demanded by the law nor does it satisfy the penal demands required by the law and it is therein those two aspects that constitute reconciliation/atonment and thus justification of sinners.
in that SIN must demand of God. Ridiculous.
What? Are you denying that sin has not penal consequences demanded by God's Justice? Yes, God demands that sin be punished and that is the demand of His law - the wages of sin is death -spiritual, phyiscal and eternal.
Let me place the difficulties with your view. If God the Father was pouring out His wrath on the Second Person of the Trinity,
He is pouring out his wrath on what the incarnation provided as a sacrifice (Heb. 10:5-9) or upon the SECOND ADAM - which is DEATH. The Second Person of the Trinity cannot suffer death in any form whatsoever and that is why the incarnation so that the humanity which is capable of suffering death could suffer and die.
I am only denying that deity is humanity or humanity is deity and the necessity of the incarnation to make atonement possible as it was not possible for the Second Person of the Trinity in regard to deity.
then God was divided against Himself, God the Father hating His own Word against the scriptures teaching that they are one.
The deity and humanity of Christ must be differianted as they are not "one" in regard to SAMENESS but that is the assumption your argument is based upon. It is God the Father that put the Son to death and the Scripture makes that clear:
Isa. 53:10 ¶
Yet it pleased the LORD to bruise him;
he hath put him to grief: when
thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.
11 He shall see of the travail of his soul, and shall be satisfied:
Or that the Father guilty of the greatest evil of all time (pouring out the punishment for all sin on an innocent man, knowing that he is innocent),
Here is the crux of our disagreement and the real evil of your theory. He acted on the cross as the Second Adam by passive obedience whereby the obedience of "one" shall many be made righteous. This is stated in direct contrast to Adam and by "one man's disobedience" many were made sinners and many be dead. Therefore, in that representative capacity he was "made to be sin" "FOR US" in our place as our sins were imputed to him just as the sins of the peopel had been imputed to the goat by a symbolic act of imputation - laying on of hands.
or if Christ were truly guilty and deserved all that punishment, then His suffering would be of no benefit to us.
Another straw man argument! He deserved that punishment in his capacity of an ordained REPRESENTATIVE "for us" in the place of sinners and thus God poured out his wrath JUSTLY as Christ REPRESENTED sinners on the cross who did indeed deserve the wrath of God.
Or that God needs to pay of sin or the devil. All three don't work.
All three are mere straw men arguments that avoid the real position I take. He acted as the Second Adam both in his active and passive obedience as a substitutionary representative for his people.
