Real presence of Christ in the Eucharist

The doctrine that Christ is truly present in the Eucharist, though Christian traditions differ on the nature and manner of that presence.

Transubstantiation: The Catholic doctrine that bread and wine become Christ’s body and blood while their appearances remain. It explains the Catholic account of how Christ is present in the Eucharist.
Eucharist: A Christian sacrament or rite in which bread and wine are consecrated and shared in remembrance of Jesus. The doctrine concerns the meaning of Christ’s presence within this sacrament.
Last Supper: The final meal Jesus shared with his disciples before his arrest, remembered in Christian accounts of the Eucharist. The institution narratives provide the central words behind Eucharistic interpretations.
Adoration of the Blessed Sacrament: A Catholic practice of worship directed toward Christ believed to be present in the consecrated Eucharist. It follows from treating the consecrated host as Christ truly present.
Consubstantiation: A term often used for the view that Christ’s body and blood coexist with the bread and wine in the Eucharist. It is commonly contrasted with transubstantiation, though many Lutherans reject the term.
Real presence: The Christian doctrine that Christ is truly present in the Eucharist, understood differently among traditions. This broader formulation includes the Eucharistic doctrine expressed on this page.
1 Corinthians 11: A New Testament chapter in which Paul recounts the Lord’s Supper and warns against receiving it unworthily. Paul’s language about the body and blood became foundational to debates over Eucharistic presence.
Eucharistic reservation: The keeping of consecrated bread for later communion or devotion. Reservation makes sense in traditions that hold Christ remains present after the service.
Memorialism: The view that the Eucharist chiefly commemorates Christ’s sacrifice rather than conveying his bodily presence. It contrasts with accounts that affirm Christ is objectively present in the sacrament.
Consecration: A religious act that sets something apart for sacred use, including the blessing of Eucharistic bread and wine. Traditions connect Christ’s Eucharistic presence to the consecration in distinct ways.
