In my previous post, I showed how the essence of heresy is to resolve a biblical paradox in one direction or the other in order to satisfy the human need for a consistent rational explanation of things; and how the early church, on the contrary, used reason not to resolve or dismiss paradox and mystery, but rather to protect it. Examples included the writings of Irenaeus, Gregory Nazianzen, and Gregory of Nyssa against heresy (protecting the essentially paradoxical nature of the whole Gospel message), and the “four fences” of the Chalcedonian Definition (protecting the paradox that Jesus was both fully God and fully human).

Now we move to the medieval period for two more examples of this use of reason to protect, rather than resolve or dismiss, the paradox and mystery at the heart of Christian theology – that is, the Incarnation.

The first example is the doctrine of transubstantiation, promulgated at the Fourth Lateran Council in 1215. This explanation of how the Eucharist “works” extends the Chalcedonian explanation that one person (Christ) can indeed be both 100% God and 100% human, to a nuanced piece of (Aristotelian) scientific reasoning on how the same sort of “this and also that” reality can be true of the Eucharistic elements. In other words, transubstantiation tried to explain, in terms accessible to scientific reason, how Jesus’ words “This is my body, this is my blood” can possibly be true.

The second example comes from the teachings of Anselm of Canterbury and Peter Abelard, both of whom we’ve already met, and looks at their reasoned explanations of the bloody scandal that was the Crucifixion. Why on earth would God have to redeem his human creatures in such a bizarre and painful way? If you’re a thoughtful Christian or a thoughtful non-Christian considering the claims of the Christian faith, then you’ve likely wondered this yourself. Again, Anselm and Abelard used forms of reasoned explanation that made good sense in their cultural contexts to explain this paradox: God died.

In other words, the divine Being who “has His own being in Himself” ceased, as all creatures do, to be! Anselm and Abelard, both brilliant dialecticians, both refused to use reason (in the mode of the early heretics) to flatten this paradox in one direction (Jesus was not really human and thus God did not really die–the docetist heresy) or the other (Jesus was not really God, and thus God did not really die–the Arian heresy). Instead, each used cultural materials to protect that central mystery while offering reasonable explanations for why the God the Second Person of the Trinity found it necessary to die on the cross–the ultimate Being submitting, however temporarily, to death, just like a sinful human.

Here’s how I work all of this out in the “theology chapter” of Getting Medieval with C S Lewis: Continue reading →
