Exactly the issue with universalism, salvation is no longer found through the cross since men pay the price of their own sins.
That's exactly the issue with ECT and satisfaction/substitution (S/S) atonement theories: They overemphasize the cross to the neglect of the whole picture, i.e. the incarnation, life, death, resurrection, and ascension of the Son of God/Son of Man.
S/S theories aren't interested in transformation, only transaction. God must be appeased by some transaction. They assume that God is adversely affected in some way or other; either God's honor is hurt (satisfaction), God's wrath must be satisfied (substitution), or God has to free humanity from a source that somehow is in competition with God (ransom-in the old "sold to the devil" theories). All of these present a weak, anthropomorphic image of God, a God who must make a transaction to save God's own creation. That's pitiful.
First, whatever theories we come up with we must assume 1. They are inadequate to describe, in all its fullness, what God is doing in Christ. We don't know God's side of things; we only know what God reveals. That revelation (Christ) is sufficient for what we need, but our theories about that revelation are just that: theories. 2. Therefore, we should take all atonement theories with a grain of salt, they are human constructs.
That said, I think a combination of theories works best:
1. Recapitulation Theory (Ireneaus): Christ became like us so that we could become like him. To recapitulation is to bring everything under one principle. All things are being reconciled to God through Christ. The mechanism for doing this is the incarnation, life, death, resurrection, ascension. That is- the whole package, not just the cross.
The cross reveals the epitome of the destructive nature of evil, i.e., we sought to destroy our own Creator-deicide. The resurrection reveals evil's impotence in relation to the God of love and life.
2. Christus Victor: Christ takes the consequences of human sin and evil on himself, not to repay the Father or be punished, as if God needs anything or has a wrath that must be satisfied, but to transform death into life, despair into hope, sorrow into joy, corruption into everlastingess. I know the historical connection between CV and ancient ransom theories. Initially, we were being ransomed from the devil. Eventually, it shifted to us being ransomed from the powers of sin, death, and hell. That's fine as long as we acknowledge the dualistic notions the metaphor of "paying a ransom" can give rise to. We might be overpowered by sin, death, and hell; but these have absolutely no power over God. God is not paying anyone or anything. God is simply revealing the reality of the situation so that we can trust and go forward in faith. In other words, the cross reveals God's power and love (John 3:16). But the goal of all of it is union between God and humanity, which is achieved in his own person before one single nail is driven.
3. Moral influence (Abelard): The Holy Spirit uses the revelation of Christ (the whole thing, not just the cross) to transform our hearts and minds so that we become like Christ (Recapitulation). The power is not in our belief in theories but in the Spirit working in us. transforming us.
Abelard was right; Anselm's theory (and Calvin's by association since he basically copied Anselm) is too anthropomorphic. God is like a feudal warlord, which was Anselm's experience and superimposed on the cross. More than that, there is no shadow of turning with God. Divine love and the divine will are not connected to a switch that is turned on and off by the cross.
