Transubstantiation
The bread and wine become Christ's body and blood while still looking like bread and wine
Transubstantiation, defined as Catholic doctrine and articulated by Aquinas after the Fourth Lateran Council, teaches that the substance of the bread and wine is changed into the body and blood of Christ while their outward appearances remain. The Orthodox affirm a real presence but reject the term and its Aristotelian framing, and most Protestant traditions reject both the term and the doctrine, even where they affirm Christ's presence.
