St. Gregory Palamas on the Atonement…
“Man was led into his captivity when he experienced God’s wrath, this wrath being the good God’s just abandonment of man. God had to be reconciled with the human race, for otherwise mankind could not be set free from the servitude. A sacrifice was needed to reconcile the Father on high with us and to sanctify us, since we had been soiled by fellowship with the evil one. There had to be a sacrifice which both cleansed and was clean, and a purified and sinless priest” (Christopher Veniamin, trans. Saint Gregory Palamas: The Homilies (Waymart, PA: Mount Thabor Publishing, 2009) p. 124).
“Christ overturned the devil through suffering and His flesh which He offered as a sacrifice to God the Father, as a pure and altogether holy victim — how great is His gift! — and reconciled God to our human race” (p.125).
“For this reason the lord patiently endured for our sake a death He was not obliged to undergo, to redeem us, who were obliged to suffer death, from servitude to the devil and death, by which I mean death both of the soul and of the body, temporary and eternal. Since He gave His blood, which was sinless and therefore guiltless, as a ransom for us who were liable to punishment because of our sins, He redeemed us from our guilt. He forgave us our sins, tore up the record of them on the Cross and delivered us from the Devil’s tyranny (cf. Col 2:14-15)”( p. 128f).”
