His Humanity belongs to HIM. It’s not as if it’s a Limp-Body loosely attached. It is IN His Humanity and BY His Humanity that “God” CAN Drink from “God” all that “God” Requires of Humanity.
Opponents of PSA insist God *Cannot* Decree the Movement of His Own Decreed Penalty over d *Does* Drink from God all that God Requires of Humanity.
God doesn’t Punish God, because He doesn’t have to, but God DOES interface with Privation & Law & Wrath & Adam & God-Forsakenness *in* *Himself* *by* *Himself* *as* *Himself* and *in* His Humanity as God DOES Drink from God all that God Requires of Humanity.
Wrath is Averted as the Father Decrees the Movement of His Own Decreed Penalty from “out-there” to “in-here”. The Means of Wrath Aversion retains His Decreed Penalty.
Scripture affirms Chalcedonian Christological Predication in The Son’s Godforsakenness and in the Father’s Decree to Move His Own Decreed Penalty from “them” over to “Him”. All of that is impossible but for the uncanny Double Solidarity coupled with Double Consubstantiality vis-à-vis Theanthropos.
Paraphrasing HH: “Technically the Decree to relocate the Penalty of Sin is from the Trinity, and the Son is taking it on IN his humanity. The problem comes from over-emphasis on the PSA aspect to the exclusion of the entire economy. Now modernist orthodox are doing that same error by over-emphasizing the rest of economy to the exclusion of the penal and substitutionary aspects.”
