I am beginning to see how you put the logical steps together to arrive at this. If you can read into the Levitical models of atonement we have recorded as cleansing and purification only faith.
I am not reading purification only, but since we were discussing the atonement in the OT (the Day of Atonement) I was reading the passages dealing with the Day of Atonement.
"Atonement" is defined as "purification" by the actual passage. But this is one of two ritualistic components. The other is the "scapegoat" ("totegoat", the animal set aside for Azazel).
The problem with your theory is it not supported by the biblical text (Scripture does not differentiate in type making atonement for the tent of meeting, for the altar, and for the sins of the people.... all are the same making of atonement).
You have created a created a new category and have insisted this neo-atonement be the primary way to view the work of the Father redeeming us.
In your opinion why did God omit substitution in the biblical text but was very specific that "making atonement" is "cleansing"?
...ignore all connection of God's reaction to our sin as "wrath" and all references of this as being possible to be propitiated or atoned for, then all references of justice and "the just for the unjust" you are on your way.
I certainly have not ignored God's "reaction" (I would say judgment) towards the wicked. The wicked "store up wrath for themselves for the day of wrath." God's wrath will be expressed on all wickedness.
In fact, this is what biblical atonement takes care of by satisfying the demands of the law, yet as God's righteousness manifested apart from the law.
On the "day of wrath" God will punish the wicked. All who have not been "cleansed from all unrighteousness", who have not "died to the flesh", who have not been made new creations" will absolutely be cast out.
But God is just. He will justly declare the new creations made in Christ's image innocent of sin. And He will condemn the wicked.
God being "just and the justifier of the one who has faith in Christ" is why God passed over OT sins until the Promise has come (read the passage as you are misapplying that verse).
God justifiies the one who has faith in Christ. We are made into Christ's image, given a new heart and spirit. Those of us who are Christians, who believe and have not been carried away from the faith once delivered by philosophy, will be righteous. We will be glorified. That is our destiny, joint heirs with Christ.
But God is also just. He will not punish the righteous but He will also in no way clear the guilty.
The crux of your argument is neoGreco-Roman philosophy. You cannot acceot a manifestation of God's righteousness apart from the law even if it fulfills the requirements of the law.
Why? Because you have adopted the secular philosophy ("all crimes must be punished, punishment satisfies the demands of the law") by "Christianizing" it (all sins must be punished, punishment satisfies the demands of divine justice).
But the Atonement is simply not the work of the Father punishing Jesus for our sins instead of punishing us. Instead the Atonement is the work of Christ cleansing us, the work of God destroying who we were to recreate us in the image of Christ.
If you can add to that a reworking of those obvious passages in Isaiah where "someone" is bruised for our transgressions
Why would I even consider such? Christ was bruised for our transgressions, He bore our sins bodily, He shared our infirmity, He was made sin for us, He shared our humanity, He came in the likeness of sinful flesh, He was made flesh, and He died in the flesh as flesh will not enter the kingdom of God.
