The short answer

Transubstantiation is the teaching that the whole substance of the bread and wine is changed into the substance of Christ's body and blood, while the appearances remain. Trent and Aquinas state it, and Aquinas argues for it from the words 'This is my body'. Calvin, Bradford, Luther, Hodge, and the Reformation confessions reject it from Scripture, the senses, and the nature of a sacrament. Ambrose says the sacramental elements are transformed into the Flesh and the Blood by holy prayer, while Theodoret says the Lord called the symbols his body and blood without changing their nature.

The Catholic teaching

12 passages · 5 writers · 1200s to 1900s

Aquinas, the Council of Trent, and Jacobus de Voragine state that the whole substance of the bread and wine is changed into Christ's body and blood. David S. Schaff reports that the Fourth Lateran Council defined transubstantiation in 1215, after which it was heresy to believe otherwise.

1265–1273 · Thomas Aquinas, Summa Theologica III, q. 75, a. 4, co.

Consequently, no natural or created agent can act except by changing the form in something; and on this account every change made according to nature's laws is a formal change. But God is infinite act, as stated in the FP, Q[7], A[1]; Q[26], A[2]; hence His action extends to the whole nature of being. Therefore He can work not only formal conversion, so that diverse forms succeed each other in the same subject; but also the change of all being, so that, to wit, the whole substance of one thing be changed into the whole substance of another. 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."

1265–1273 · Thomas Aquinas, Summa Theologica III, q. 78, a. 2, co.

Accordingly, in this form also the conversion ought to be expressed as in "being," to which the intention is referred. And since the conversion is expressed in this form as in "being," it is necessary for the extremes of the conversion to be signified as they exist in the fact of conversion. But then the term "whereunto" has the proper nature of its own substance; whereas the term "whence" does not remain in its own substance, but only as to the accidents whereby it comes under the senses, and can be determined in relation to the senses. Hence the term "whence" of the conversion is conveniently expressed by the demonstrative pronoun, relative to the sensible accidents which continue; but the term "whereunto" is expressed by the noun signifying the nature of the thing which terminates the conversion, and this is Christ's entire body, and not merely His flesh; as was said above (Q[76], A[1], ad 2). Hence this form is most appropriate: "This is My body."

1546–1563 · Council of Trent, Canons and Dogmatic Decrees of the Council of Trent s13.c4

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.

Protestant objections

Calvin, Bradford, Luther, Barnes, and Browne argue from Scripture that the bread remains: Christ's words do not turn bread into body, and Paul still calls it bread. Hodge, Tillotson, and South argue from the senses, which show no change in the elements. Calvin, Bayly, and the Westminster and Savoy confessions argue from the nature of a sacrament, which would be overthrown if the substance did not remain. The Heidelberg Catechism and the 1689 Baptist Confession say the bread and wine remain bread and wine.

1559 · John Calvin, Institutes of the Christian Religion 4.17.20

The advocates of transubstantiation insist, that by the pronoun, this, is denoted the appearance of bread, because the whole complexion of our Saviour’s address is an act of consecration, and there is no substance which can be demonstrated. But if they adhere so religiously to the words, inasmuch as that which our Saviour gave to his disciples he declared to be his body, there is nothing more alien from the strict meaning of the words than the fiction, that what was bread is now body. What Christ takes into his hands, and gives to the apostles, he declares to be his body; but he had taken bread, and, therefore, who sees not that what is given is still bread? Hence, nothing can be more absurd than to transfer what is affirmed of bread to the species of bread. Others, in interpreting the particle is, as equivalent to being transubstantiated, have recourse to a gloss which is forced and violently wrested.

1563 · Zacharias Ursinus and Caspar Olevianus (Heidelberg theologians), The Heidelberg Catechism 78

Q. Do the bread and wine become the real body and blood of Christ? A. No. Just as the water of baptism is not changed into Christ’s blood and does not itself wash away sins but is simply a divine sign and assurance of these things, so too the holy bread of the Lord’s Supper does not become the body of Christ itself, even though it is called the body of Christ in keeping with the nature and language of sacraments.

1872 · Charles Hodge, Systematic Theology, vol. 3 (Part III, chapters XV-XX; Part IV, Eschatology) 3.20.19

The form, colour, taste, odour, the specific gravity, their chemical affinities, and their nutritive qualities remain the same. So far as the senses, chemical analysis, and physics are concerned or are to be trusted, no change has taken place. As the sensible properties of the bread and wine do not and cannot inhere in the substance of Christ’s body and blood, and as their own substance no longer exists, those properties do not inhere in any substance.

The early writers and the history of the doctrine

7 passages · 6 writers · 300s to 1800s

Ambrose says the sacramental elements are transformed into the Flesh and the Blood by the mysterious efficacy of holy prayer, and Theodoret says the Lord called the symbols his body and blood without changing their nature. Calvin quotes a Father who says the substance of bread and wine remains, and says transubstantiation was not yet recognized in Bernard's age. Luther says the Fathers never mentioned transubstantiation, and Tillotson says Pope Gelasius denied any substantial change. Nevin says the early Church knew no transubstantiation.

378 · Ambrose of Milan, Exposition of the Christian Faith (De fide) 4.10.125

Hear His own words: “A spirit hath not flesh and bones.” Now we, as often as we receive the Sacramental Elements, which by the mysterious efficacy of holy prayer are transformed into the Flesh and the Blood, “do show the Lord’s Death.”

c. 447–448 · Theodoret of Cyrus, Eranistes (Dialogues) 1

Orth.—To them that are initiated in divine things the intention is plain. For he wished the partakers in the divine mysteries not to give heed to the nature of the visible objects, but, by means of the variation of the names, to believe the change wrought of grace. For He, we know, who spoke of his natural body as corn and bread, and, again, called Himself a vine, dignified the visible symbols by the appellation of the body and blood, not because He had changed their nature, but because to their nature He had added grace.

1520 · Martin Luther, On the Babylonish Captivity of the Church supper

The Church, however, kept the right faith for more than twelve centuries, nor did the holy Fathers ever or anywhere make mention of this transubstantiation (a portentous word and dream indeed), until the counterfeit Aristotelian philosophy began to make its inroads on the Church within these last three hundred years, during which many other erroneous conclusions have also been arrived at, such as:—that the Divine essence is neither generated nor generates; that the soul is the substantial form of the human body; and other like assertions, which are made absolutely without reason or cause, as the Cardinal of Cambray himself confesses.

1846 · John Williamson Nevin, The Mystical Presence: A Vindication of the Reformed or Calvinistic Doctrine of the Holy Eucharist 2.3

We hear of no transubstantiation of the elements into Christ's body and blood, as afterwards taught by the Church of Rome. They are called, indeed, his body and blood; but only in a sacramental or liturgical sense. We hear of no material or local presence of his flesh, in the Lutheran sense; no tactual communication with his glorified body; no reception of his life in a simply oral way.
