Right. Probably should be clear on definitions before we delve into Scripture. OP, I hope this thread is as helpful as you hoped.
Satisfaction Theory, as my limited layman’s brain understands it, is the idea that:
Basically, through Adam’s fall and our sin, humanity has offended God. God’s justice and righteousness demands recompense, which humans are unable to pay on their own. Yet God, mercifully, has supplied the Sacrificial Lamb, just as He did when sparing Isaac. Now we Western Christians (Catholics and Protestants) do have important disagreements about the specifics (
Theopedia explains: “For [broad Satisfaction Theorists] Christ obeyed where we should have obeyed; for [specific Penal Substitution Theorists], he was punished where we should have been punished.”), but these finer points are irrelevant in this discussion of Eastern and Western approaches to Atonement.
Now, for the benefit of this Western layman, could you please explain the Eastern view on Atonement, and how the process of Theosis works into that?
*Theopedia has an overtly-Calvinistic bent, so read it with a few grains. But the definition is close enough.
Well I’ll give you a few quotations.
But beyond all this, there was a debt owing which must needs be paid; for, as I said before, all men were due to die. Here, then, is the second reason why the Word dwelt among us, namely that having proved His Godhead by His works, He might offer the sacrifice on behalf of all, surrendering His own temple to death in place of all, to settle man’s account with death and free him from the primal transgression. In the same act also He showed Himself mightier than death, displaying His own body incorruptible as the first-fruits of the resurrection. -
St Athanasius
For the solidarity of mankind is such that, by virtue of the Word’s indwelling in a single human body, the corruption which goes with death has lost its power over all. You know how it is when some great king enters a large city and dwells in one of its houses; because of his dwelling in that single house, the whole city is honored, and enemies and robbers cease to molest it. Even so is it with the King of all; He has come into our country and dwelt in one body amidst the many, and in consequence the designs of the enemy against mankind have been foiled and the corruption of death, which formerly held them in its power, has simply ceased to be. For the human race would have perished utterly had not the Lord and Savior of all, the Son of God, come among us to put an end to death. -
St Athanasius
Now we are to examine another fact and dogma, neglected by most people, but in my judgment well worth enquiring into. To Whom was that Blood offered that was shed for us, and why was It shed? I mean the precious and famous Blood of our God and High priest and Sacrifice. We were detained in bondage by the Evil One, sold under sin, and receiving pleasure in exchange for wickedness. Now, since a ransom belongs only to him who holds in bondage, I ask to whom was this offered, and for what cause? If to the Evil One, fie upon the outrage! If the robber receives ransom, not only from God, but a ransom which consists of God Himself, and has such an illustrious payment for his tyranny, a payment for whose sake it would have been right for him to have left us alone altogether. But if to the Father, I ask first, how? For it was not by Him that we were being oppressed; and next, On what principle did the Blood of His Only begotten Son delight the Father, Who would not receive even Isaac, when he was being offered by his Father, but changed the sacrifice, putting a ram in the place of the human victim? Is it not evident that the Father accepts Him, but neither asked for Him nor demanded Him; but on account of the Incarnation, and because Humanity must be sanctified by the Humanity of God, that He might deliver us Himself, and overcome the tyrant, and draw us to Himself by the mediation of His Son, Who also arranged this to the honour of the Father, Whom it is manifest that He obeys in all things? -
St Gregory the Theologian
Therefore the Word of God, Himself God, the Son of God who in the beginning was with God, through whom all things were made and without whom was nothing made John 1:1-3, with the purpose of delivering man from eternal death, became man: so bending Himself to take on Him our humility without decrease in His own majesty, that remaining what He was and assuming what He was not, He might unite the true form of a slave to that form in which He is equal to God the Father, and join both natures together by such a compact that the lower should not be swallowed up in its exaltation nor the higher impaired by its new associate. Without detriment therefore to the properties of either substance which then came together in one person, majesty took on humility, strength weakness, eternity mortality: and for the paying off of the debt,
belonging to our condition, inviolable nature was united with possible nature, and true God and true man were combined to form one Lord, so that, as suited the needs of our case, one and the same Mediator between God and men, the Man Christ Jesus, could both die with the one and rise again with the other. -
