The True Presence

WHAT IS THE TRUE PRESENCE?

"In the celebration of the Eucharist, the glorified Christ becomes present under the appearances of bread and wine in a way that is unique, a way that is uniquely suited to the Eucharist. In the Church's traditional theological language, in the act of consecration during the Eucharist the "substance" of the bread and wine is changed by the power of the Holy Spirit into the "substance" of the Body and Blood of Jesus Christ. At the same time, the "accidents" or appearances of bread and wine remain. "Substance" and "accident" are here used as philosophical terms that have been adapted by great medieval theologians such as St. Thomas Aquinas in their efforts to understand and explain the faith. Such terms are used to convey the fact that what appears to be bread and wine in every way (at the level of "accidents" or physical attributes - that is, what can be seen, touched, tasted, or measured) in fact is now the Body and Blood of Christ (at the level of "substance" or deepest reality). This change at the level of substance from bread and wine into the Body and Blood of Christ is called "transubstantiation." According to Catholic faith, we can speak of the Real Presence of Christ in the Eucharist because this transubstantiation has occurred (cf. Catechism, no. 1376). This is a great mystery of our faith—we can only know it from Christ's teaching given us in the Scriptures and in the Tradition of the Church."
