Consubstantiation

Consubstantiation is a Christian theological doctrine that (like transubstantiation) describes the real presence of Christ in the Eucharist. It holds that during the sacrament, the substance of the body and blood of Christ are present alongside the substance of the bread and wine, which remain present. It was part of the doctrines of Lollardy, and considered a heresy by the Catholic Church. It was later championed by Edward Pusey of the Oxford Movement, and is therefore held by many high church Anglicans, seemingly contrary to the Black Rubric of the Book of Common Prayer. The Irvingian Churches (such as the New Apostolic Church) adhere to consubstantiation as the explanation of the real presence of Christ in the Eucharist. Lutherans affirm the physical presence of Christ's body and blood alongside the bread and wine through a sacramental union, but typically reject the label of "consubstantiation" as an oversimplification.
