The catechsim of the Catholic Church states: The Holy Eucharist is a sacrament and a sacrifice. In the Holy Eucharist, under the appearances of bread and wine, the Lord Christ is contained, offered, and received.(a) The whole Christ is really, truly, and substantially present in the Holy Eucharist. We use the words "really, truly, and substantially" to describe Christ's presence in the Holy Eucharist in order to distinguish Our Lord's teaching from that of mere men who falsely teach that the Holy Eucharist is only a sign or figure of Christ, or that He is present only by His power

348. Did anything of the bread and wine remain after their substance had been changed into Our Lord's body and blood?After the substance of the bread and wine had been changed into Our Lord's body and blood, there remained only the appearances of bread and wine.(a) Because the appearances of bread and wine remain in the Holy Eucharist, we cannot see Christ with our bodily eyes in this sacrament. We do see Him, however, with the eyes of faith. Our bodily eyes, moreover, do not deceive us when they see the appearances of bread and wine for these appearances really remain after the Consecration of the Mass.

349. What do we mean by the appearances of bread and wine?By the appearances of bread and wine we mean their color, taste, weight, shape, and whatever else appears to the senses.

350. What is the change of the entire substance of the bread and wine into the body and blood of Christ called?The change of the entire substance of the bread and wine into the body and blood of Christ is called Transubstantiation.351. Is Jesus Christ whole and entire both under the appearances of bread and under the appearances of wine?Jesus Christ is whole and entire both under the appearances of bread and under the appearances of wine.(a) We know that Christ is whole and entire under both appearances because, "Christ having risen from the dead, dies now no more" (Romans 6:9). Because Christ cannot die, His blood must remain united always to His body, and His soul to both. The divinity of Christ, moreover, always remains united to His body and blood and soul because He is God made man.(b) The whole Christ is present under each part of the sacred appearances and remains present as long as the sacred appearances remain.r.
