Not too long ago here at the blog I wrote some posts on annihilationism or what some call evangelical conditionalism; the idea being that there is not an eternal hell, instead when someone dies outside of Christ, ultimately, their existence and being is dis-integrated by its un-hinging from the eternal life of God. There are some interesting implications surrounding this; and the folks at ReThinking Hell (proponents of annihilationism) want to present the implications they see in a way that is grounded in biblical exegesis and reality. Indeed, as orthodox Christians, who wouldn’t want to ground their thinking about this issue in the reality of the biblical witness? But as is typical there is always more to the story, never less, than just quoting bible passages, or doing word studies; indeed, there is always an inner-theological reality that allows Scripture to presume what it does in its occasional teachings.
As I originally opined on this issue what I stated was that there was a need to think about this issue from a theological exegetical point of view, such that the Dogmatic loci have the opportunity to supply the necessary pressure for biblical exegesis to have the sort of fully rounded elucidation that it ought to have when dealing with this particular teaching among every other biblical teaching. What I suggested originally was that at base annihilationism has to do with the way a theological anthropology is detailed, and how that gets developed vis-à-vis a doctrine of election/reprobation. When it comes to these particular loci my go to theologians are of course Karl Barth and Thomas Torrance (not to mention their reliance on Athanasius when it comes to these themes). What I suggest is that if we understand all human being to be grounded in Christ’s vicarious humanity—which is what Barth’s and Torrance’s reformulated doctrine of election details—if we see human ontology grounded in Christ’s election to become human for us, then human being has an ec-static source that is not contingent upon itself, but upon God (insofar as the Son’s humanity is given enhypostatic particularity through his being as the eternal Logos in the triune life). If this is so, then human being, even if that being refuses to acknowledge its reality by repentance and coming into full union with its reality in Christ, is held together for all eternity just as sure as the humanity of Christ is of the indestructible sort (Hebrews). Some might take this to mean that universalism then is the conclusion; versus annihilationism. But Torrance explicitly rejects that conclusion, and simply lives in the tension of the biblical witness. He works out of the implications of the Incarnation, and at the same time, dialectically allows Scripture’s teaching to chasten thinking that might lead us to think that all human being will ultimately experience eternal life simply because its ontological ground is in the humanity of Jesus Christ. Torrance repudiates these sorts of logico-causal/necessitarian conclusions just as Einstein rejected mechanical conclusions about the cosmos based upon the reality of relativity in the time-space continuum.
Geordie Ziegler helps to elucidate what we have been thinking about above and helps to reinforce my suggestions in regard to hell, election, and annihilationism in the theology of Thomas Torrance. Ziegler writes:
Because God is committed to his creature, human beings are bound eternally in an “existential relation to God.” Accordingly, Torrance rejects equating God’s final judgment with annihilation. In an effort to root final judgment and reprobation biblically, he develops the Old Testament concepts of the curse of God and sheol. In being cursed, the reprobate are given up to their own uncleanness, separated from the face of God and banished from creation into “outer darkness.” But, fundamentally, this is “a banishment to their own denial of their being in God.” It is the confirmation of their choice to exist outside of the covenant of God, as those who do not belong to it. Whereas sheol, as Torrance expounds it, is this state of existence “in darkness behind God’s back . . . in man’s self-chosen perversity and blindness.” Sheol is a kind of suspended darkness, that already casts its shadow over all sinners as their self-chosen destiny, yet awaits God’s final acts of judgment. The curse then is God’s ultimate and final judgment in which those who cast themselves upon God’s wrath and judgment will be justified; and those who choose to remain in their alienation will be utterly banished. Torrance describes hell as “the chasm that separates man from God in the very existence of sinful man,” who is conditioned and determined by sin and guilt. Hell is not an abstract place, nor is it the no-thing of nothingness. Hell is the personal and concrete existence of the human being in alienation from God. It is the sinner choosing isolation from God’s love. As such, the alienation of hell is always a possibility—for both the living as well as for the living dead. For those whose “ultimate reaction” is to deny God’s claim upon them, they will bear the pain of a continued existence of “utter and final judgement within existential relation to God.” God gives sinners the freedom to deny his claim upon them, yet his claim remains nonetheless.
The key to understanding this contra annihiliationism is to recognize that human being, all of human being’s perduring is encompassed by the reality that God’s humanity is humanity, and as such humanity can never be eradicated, none of it, by virtue of this. In other words, if the humanity of God stands behind the back, as it were, of the humanity of all instances of humanity (this gets us into another quagmire in regard to dealing with a concern about positing a metaphysical humanity, which we will have to engage later) then humanity, even if it spiritually fails to submit to its reality in Christ, nonetheless will endure through all the æon’s of time to come (for all eternity). As far as Torrance’s (and Barth’s) doctrine of election, and attending theological anthropology vis-à-vis redemption, leading to Christian universalism: this need not be the conclusion precisely at the point that Scripture itself delimits this as a viable conclusion in regard to the experience of eternal life in Christ. In other words, people can reject what in fact stands over them, their very life in Christ. Some might think this then leads to the binary of Calvinism and Arminianism, as far as so called ‘free-will,’ but that’s only if we believe that the theological paradigm and theory of causation that classical Calvinism and Arminianism are embedded within, are the only ways to think about a relation inhering between God and his creation. But that’s not the only way to think about such things.
