Yes it pleased The Father to give His Son to be crushed at the cross, however it also pleased The Son to crush His own self, and it pleased The Holy SpiritThis is the contention that is nonsensical to me. How can the Son be bearing penalty for sin that is not being accounted to Him by the Father? Why does the Son taking on a distinct operation, namely the incarnation, not count as "splitting the Trinity" but Him bearing sin and it's penalty does? Moreover, what do you do with a passage like Isaiah 53:10-12? "It pleased Yahweh to crush Him, He will bear their iniquities, He bore the sin of many."
I agree that the cross shows both God's judgement and mercy, however since Christ's human nature is not a second person, and there is One Divine Will, we don't believe that Christ was separated from The Father because of sin, but rather that He took on the punishment for sin. Growing up going to bible churches, non-denom, and baptist churches it was my impression that the later development of penal substitution in western Protestantism (which also in part stems from Latin theology) states that The Son was in hell for three days as a separation, a punishment from The Father. We Orthodox reject that, because The Son bore our punishment in union with The Spirit and The Father. He was crushed by The Father's Will and of His own Divine (which is the same as The Father's) and His Human Will.You don't believe God has wrath against sinners? I propose that the cross shows both the wrath of God against sin and the mercy of God to His chosen ones.
Most types of animal sacrifice in the Old Testament are for purifying the altar/tabernacle space so that God's presence could dwell among them. They needed the blood of the animal to sprinkle around the altar and cleanse things, to do that the animal would be killed. There was also the scapegoat, which was a goat iirc, and the sins of the people would be transferred to the goat and the goat would be kicked out of the camp.The types of animal sacrifice are one of the biggest reasons I am convinced of PSA, that is one of the big points in Hebrews. And it is not the claim of PSA that the Father "needs" sacrifice. He only "needs" sacrifice in the sense that His justice towards our sin has to be carried out if we are to enter into His presence.
Christ fulfills all of the law and the prophets, so He fulfills all of these things, and in the Eucharist He gives His Blood into the temple of the body of the Orthodox Christian, so that by His Flesh and The Holy Spirit, The Triune God dwells in the temple of the body.
Since Christ is God, when He takes sin upon the cross, He burns it up! He is not separated from The Father, He is always One with The Father, and if Christ was separated from The Father, how can we be united to The Father through Christ? Christ was crushed, but willingly, and not in separation from the Godhead
