“After the blessing Jesus still calls the cup "the fruit of the vine," and Paul still calls the bread "bread." So nothing changed. Transubstantiation is a medieval word for a medieval idea.”

Verses cited for this objection: Matt. 26:26-29, Mk. 15:22-25, 1 Cor. 11:23-28

Short answer

The Church teaches that by the consecration the whole substance of the bread and wine is changed into the Body and Blood of Christ, while the appearances of bread and wine remain. Scripture keeps the names "bread" and "cup" for what is seen, and the same passages call what is received the body and blood of the Lord. The word transubstantiation came into use in the Middle Ages. The belief that the bread and wine are changed is found in the Fathers many centuries before the word.

Drafted from primary sources. Every quotation is checked against the page it links to. The project's objection table cites Mk. 15:22-25, which is the crucifixion. This is almost certainly a slip for Mark 14:22-25, the Last Supper, and the timeline quotes that passage. The verses field is kept as the table gives it.

Where this teaching appears on the Offshoots timelines: 1079, The change of the bread and wine denied: Berengar of Tours.

“When, therefore, the mingled cup and the manufactured bread receives the Word of God, and the Eucharist of the blood and the body of Christ is made, from which things the substance of our flesh is increased and supported, how can they affirm that the flesh is incapable of receiving the gift of God, which is life eternal, which [flesh] is nourished from the body and blood of the Lord, and is a member of Him?”

“Let us prove that this is not what nature made, but what the blessing consecrated, and the power of blessing is greater than that of nature, because by blessing nature itself is changed. … The Lord Jesus Himself proclaims: This is My Body. … Before the blessing of the heavenly words another nature is spoken of, after the consecration the Body is signified.”

“His body and blood are truly contained in the sacrament of the altar under the forms of bread and wine, the bread and wine having been changed in substance, by God's power, into his body and blood, so that in order to achieve this mystery of unity we receive from God what he received from us.”

“And this is done by Divine power in this sacrament; for the whole substance of the bread is changed into the whole substance of Christ's body, and the whole substance of the wine into the whole substance of Christ's blood. Hence this is not a formal, but a substantial conversion; nor is it a kind of natural movement: but, with a name of its own, it can be called "transubstantiation."”

Council of Trent Session 13, Decree on the Eucharist, ch. 4

“And because that Christ, our Redeemer, declared that which He offered under the species of bread to be truly His own body, therefore has it ever been a firm belief in the Church of God, and this holy Synod doth now declare it anew, that, by the consecration of the bread and of the wine, a conversion is made of the whole substance of the bread into the substance of the body of Christ our Lord, and of the whole substance of the wine into the substance of His blood; which conversion is, by the holy Catholic Church, suitably and properly called Transubstantiation.”

“For what now lies beneath the aforementioned species is not what was there before, but something completely different; and not just in the estimation of Church belief but in reality, since once the substance or nature of the bread and wine has been changed into the body and blood of Christ, nothing remains of the bread and the wine except for the species…”
