transparent context See REFERENTIALLY TRANSPAR -. EN. transubstantiation, change of one substance into another. Aristotelian metaphysics distinguishes between substances and the accidents that inhere in them; thus, Socrates is a substance and being snub-nosed is one of his accidents. The Roman Catholic and Eastern Orthodox churches appeal to transubstantiation to explain how Jesus Christ becomes really present in the Eucharist when the consecration takes place: the whole substances of the bread and wine are transformed into the body and blood of Christ, but the accidents of the bread and wine such as their shape, color, and taste persist after the transformation. This seems to commit its adherents to holding that these persisting accidents subsequently either inhere in Christ or do not inhere in any substance. Luther proposed an alternative explanation in terms of consubstantiation that avoids this hard choice: the substances of the bread and wine coexist in the Eucharist with the body and blood of Christ after the consecration; they are united but each remains unchanged.
