Abstract

Catholic doctrine makes metaphysical claims about the Eucharist, but the distinctive language of “transubstantiation” is often treated as an historically contingent, and disposable, way of articulating these claims. Attempts to translate the metaphysics implied by “transubstantiation” into other terminology should begin by attending to the semantic assumptions of those who first articulated it. This chapter argues that the notion of substantial predication in realist semantics helps communicate a metaphysical claim which even well-intended efforts at translation into other semantic frameworks often fail to capture. An implication of the argument is that, not only does realist semantics help us understand the Catholic doctrine of transubstantiation, but the Catholic doctrine of transubstantiation helps us recapture realist semantics and the Aristotelian notion of substance.
