In the ceremony of Mass, the priest takes a piece of bread and a glass of wine and proclaims that the bread is Christ’s flesh, the wine is Christ’s blood, and by eating and drinking them the faithful attain communion with Christ. What could be more real than actually tasting Christ in your mouth? Traditionally, the priest made these bold proclamations in Latin, the ancient language of religion, law, and the secrets of life. In front of the amazed eyes of the assembled peasants the priest held high a piece of bread and exclaimed “Hoc est corpus!” — “This is the body!” — and the bread supposedly became the flesh of Christ. In the minds of the illiterate peasants, who did not speak Latin, “Hoc est corpus!” got garbled into “Hocus-pocus!” Thus was born the powerful spell that can transform a frog into a prince and a pumpkin into a carriage.6

Essential to the Catholic mind is what I would characterize as a keen sense of the prolongation of the Incarnation throughout space and time, an extension that is made possible through the mystery of the church. Catholics see God’s continued enfleshment in the oil, water, bread, imposed hands, wine, and salt of the sacraments; they appreciate it in the gestures, movements, incensations, and songs of the Liturgy; they savor it in the texts, arguments, and debates of the theologians; they sense it in the graced governance of popes and bishops; they love it in the struggles and missions of the saints; they know it in the writings of Catholic poets and in the cathedrals crafted by Catholic architects, artists, and workers. In short, all of this discloses to the Catholic eye and mind the ongoing presence of the Word made flesh, namely Christ.

The Word became Flesh, and we are beings of flesh and blood and soul. We are living in the reality of the material world – also created by God – and therefore we need this corporal visible mediation by the sacraments within the community of the believers.

The Roman Catholic doctrine of transubstantiation...claims...the "Whole substance" of the wine is converted into the blood of Christ,; the appearance of wine that remains is "merely accidental", "inhering in no substance". Transubstantiation is colloquially taught as meaning that the wine "literally" turns into the blood of Christ. Whether in its obfuscatory Aristotelian or its franker colloquial form, the claim of transubstantiation can be made only if we do serious violence to the normal meanings of words like 'substance' and 'literally'.

Of all the fathers, as many as you can name, not one has ever spoken about the sacrament as these fanatics do. None of them uses such an expression as, 'It is simply bread and wine,' or, 'Christ’s body and blood are not present.' Yet since this subject is so frequently discussed by them, it is impossible that they should not at some time have let slip such an expression as, 'It is simply bread,' or, 'Not that the body of Christ is physically present,' or the like, since they are greatly concerned not to mislead the people; actually, they simply proceed to speak as if no one doubted that Christ’s body and blood are present. Certainly among so many fathers and so many writings a negative argument should have turned up at least once, as happens in other articles; but actually they all stand uniformly and consistently on the affirmative side.

I acknowledge that the sacrament of the altar is very God's body in form of bread, but it is in another manner God's body than it is in heaven.

In reality, "Body and Blood of Christ" do not mean the material components of the man Jesus during His lifetime or in His transfigured corporeality. Rather, body and blood here mean the presence of Christ in the sign of the medium of bread and wine, which [presence] is made communicable in the here and now of sense-bound human perception.

(In an open leter to Denver Archbishop Samuel J. Aquila) Catholic sacramental theology is based on the premise that the sacraments are the work of Christ, which is the meaning of the Church’s affirmation at Trent (DS 1608) that the sacraments act ex opere operato, or, as St. Thomas wrote in the Summa, III, 68,8: ‘The sacrament is not wrought by the righteousness of either the celebrant or the recipient, but by the power of God.’ Owing to the nature of God, Christ and his works can never be diminished by any act on our part. [...] I write as a brother bishop with the suggestion that you consider offering a public clarification of your point.

Since Christ Himself said in reference to the bread: "This is My Body," who will dare remain hesitant? And since with equal clarity He asserted: "This is My Blood," who will dare entertain any doubt and say that this is not His Blood?... You have been taught these truths. Imbued with the certainty of faith, you know that what seems to be bread is not bread but the Body of Christ, although it seems to be bread when tasted. You also know that what seems to be wine is not wine but the Blood of Christ although it does taste like wine.

But because in the Sacrament all those doe meete together, therefore nothing so availeable to take away sinne, as the touching of bread and wine, with our lips.

"Catholic writers tend to see humanity struggling in a fallen world. They combine a longing for grace and redemption with a deep sense of human imperfection and sin. Evil exists, but the physical world is not evil. Nature is sacramental, shimmering with signs of sacred things....Catholicism is also intrinsically communal, a notion that goes far beyond sitting at Mass with the local congregation, extending to a mystical sense of continuity between the living and the dead. Finally, there is a habit of spiritual self-scrutiny and moral examination of conscience" (10).

The Catholic Church is like a thick steak, a glass of red wine, and a good cigar.

We have to make sure that we always recognize that we don't own the sacraments, the sacraments are the work of Christ. It is he who comes to us ... and it's his grace that takes precedence over everything else. Therefore we should see in each of those encounters with Christ in the sacraments a sacred experience even beyond our comprehension. And the one, of course, that's the supreme of everything is the Eucharist, because that's when Christ sacrificed on Calvary. We're fed with the same food that the disciples were fed at the Last Supper, and the same blood of the covenant from the cross is given to us. So again, it's Christ who is there, Christ offering the sacrifice. We are with him but it is he who does it all, it is he who feeds us.

Brethren, here in the sacrament is the rainbow of the new and better covenant, the renewed pledge of salvation purchased, and strength imparted, and blessing conferred on the believing soul. And now, as in your covenant you pay your vows — time, talent, influence, property, life, all God's, — He the Infinite, in boundless condescension stoops to whisper, "My light, my strength, my purity, my joy, my heaven, all yours." Thou hast avouched the Lord this day to be thy God, to walk in His ways, and to keep His statutes and His commandments, and His judgments, to hearken to His voice; and the Lord hath avouched thee this day to be His peculiar people, as He hath promised thee. And thus, brethren, in a mutual covenant of blessing, you do show forth His death until He come.
