The Mystery

6. The eucharist: to eat a body

Before any theology, the practice.

And the practice, severed from habit, is extraordinarily strange. It is worth stating it as a foreign observer:

A community gathers regularly. Someone speaks specific words over bread and wine. Those present stand in a line, approach one by one, and place in their mouths a piece of matter about which the community claims that it is the body of a person who was executed.

This takes place, in some form, daily, in hundreds of thousands of locations, for roughly two millennia.

The bodily structure of the act

Notice how bodily it is, layer by layer:

• It is food. Mastication, swallowing, digestion. The material crosses the boundary of the body and becomes the body eating it.
• It is a queue. Movement, waiting, order, approach.
• It is a posture. Kneeling or standing, opening the mouth or extending the palm — and these details have caused institutional conflicts.
• It is fasting beforehand. The usual precondition was for centuries the fast from midnight; today in Roman Catholic practice one hour.
• And it is shared. Everyone eats from the same.

The words, and their harshness

The passage John 6 is, for any reader, difficult:

“The one who chews my flesh and drinks my blood abides in me” (John 6:56)

The verb used in the critical verses is not the general esthiō (eat) but trōgō — chew, gnaw. It is the most bodily option available.

And the text records the scandalised reception: “This is a hard saying”, and many walked away (6:60, 6:66). That the tradition preserved in its own texts the scene in which the claim drives listeners away is remarkable.

And the pagan indictment

In the early centuries, Christians were repeatedly accused of cannibalism and of rites involving infants.

The accusation was not foolish. It was the plausible outside reading of a closed rite in which participants said they ate flesh and drank blood.

This shows two things: that the language was realistic from the start and not euphemistic, and that the practice was bodily enough to frighten.

The structurally unique

I have described thirteen systems. Many have food rules — what is permitted, when, with what preparation. Some have ritual meals.

None has as its central mystery the ingestion of a body.

Judaism has an extensive food system and the absolute prohibition of blood. Islam has ḥalāl and fasting. The Amazonian guide describes dieta, which makes body with food — and is the closest structural analogue, with entirely different content.

Here food is the person. This has no parallel in the series.

7. The theories — and all of them have dates

The practice is ancient. Its explanations are datable, and this is the point where the criterion of the whole series applies.

The first millennium: realism without mechanism

The early texts speak realistically — it is the body — without explaining how. There is no theory, there is a claim.

The first serious dispute is the 9th century (Paschasius Radbertus and Ratramnus, c. 840–850), and it is still open.

1215: the word acquires official status

The Fourth Lateran Council (1215) uses the term transsubstantiatio.

This is a dating worth keeping: the word “transubstantiation” is medieval, not apostolic. The practice precedes the theory by roughly twelve centuries.

Thomas Aquinas (13th c.): the mechanism

The Thomist formulation uses Aristotelian physics: every thing has substance (substantia) and accidents (accidentia) — the sensible properties.

In transubstantiation, the substance of the bread is replaced, and the accidents — taste, appearance, texture, chemical composition — remain.

And here an exact observation must be made, because it is misstated from both sides:

The formulation explicitly predicts that no physical measurement will show a difference. This is not retrospective evasion — it is structural to the dogma from the 13th century.

Consequently:

• Anyone who says “we analysed it and it is bread” has not refuted the dogma; they have confirmed what the dogma predicts.
• And anyone who says the dogma is a scientific claim has not read it.

The cost is that the claim becomes, by definition, unfalsifiable. This is the honest formulation, and the same criterion applies as the one I applied to the four Tibetan rlung and the four Theravāda elements: a system that cannot be falsified has not been falsified, and this is not an achievement.

1551 and 1215 versus 1520 and after

The Council of Trent (session 13, 1551) confirms transubstantiation as the dogmatic formulation, in response to the Reformation. And the Reformers divided on precisely this point, not on something secondary:

Marburg (1529) is the moment to keep: Luther and Zwingli agreed on fourteen of fifteen articles and split on the fifteenth, which was this one. The tradition divided over what a piece of bread is.

And the bodily consequence of the division

It did not remain theoretical. It changed what the bodies do:

• If the presence is substantial, the remainder is reserved, venerated, carried in procession. From this come the tabernacle, the procession of Corpus Christi (instituted 1264), kneeling.
• If it is memorial, none of this makes sense — and in parts of the Reformation these objects were destroyed.

The iconoclastic violence of the 16th century is, to a large extent, a disagreement about materiality carried out materially.

8. Baptism: the body in the water

The practice and its modification

The original form is immersion in running water, preferably. The Didache (c. 100) says so explicitly — and, characteristically, gives alternatives: if there is no running water, other water; if there is no cold, warm; if there is not enough, pour water three times on the head.

This is, structurally, the same shape as the Islamic tayammum: a provision for incapacity, written into the rule from the beginning, with the material yielding before the practice.

The archaeology confirms the development: the early baptisteries are large basins with steps. Gradually they shrink; in the Latin West affusion (pouring) becomes the norm, and immersion returns with the 16th-century Anabaptists and the baptist bodies.

And the language, which is more bodily than it looks

The Pauline formulation is not “cleansing”. It is death and burial:

“We were buried with him through baptism into death” (Rom 6:4)

The immersion is burial; the emergence is resurrection. The body enacts the death it invokes — and this explains why the immersion is not an indifferent detail for those who restored it: pouring keeps the meaning and loses the gesture.

The unrepeatable, and what it means

Baptism is not repeated. It is held to leave an indelible character.

Compare with the previous document: in Islam, as in Judaism, purity is a state that is lost and recovered, repeatedly, with named events and named procedures. Here there is one irreversible event and, separately, a repeating cycle (confession, eucharist).

The structure is not cyclical purity. It is one irreversible entry, plus maintenance.

This is a real structural difference, and one of the few cases in the series where two neighbouring traditions, of common descent and common vocabulary, have incompatible architecture for the same question.

9. The remaining sacraments as bodily acts

The list of seven stabilises in the West in the 12th century (Peter Lombard) and is confirmed at Trent. Before this the number fluctuates — another dating worth noting.

But the interest is not the number. It is that each one requires material and bodily contact:

Two observations.

First: matter is not decorative, it is required. There is no valid baptism without water. There is no eucharist without wheat bread. The scholastic terminology says materia and forma: material and words, and both are needed.

Second, and sharper: marriage requires bodies. Canon law develops the concept of matrimonium ratum et non consummatum — a marriage valid but incomplete — and non-consummation is a ground for dissolution. That is: the law of a tradition held to be sexually suspicious makes the sexual act constitutive of a sacrament.

This does not cancel chapter 2. It stands beside it, and the tension is the subject of chapter 5.

And the term that makes the difference: ex opere operato

The Western formulation says the sacrament acts “from the work performed” — not from the worth of the one performing.

An unworthy priest performs a valid baptism. The formulation crystallises in the Donatist disputes of the 4th–5th centuries, where the question was precisely this.

The consequence is institutional and enormous: validity is decoupled from personal holiness, and so the system can function at scale, with thousands of ministers of middling quality, without collapsing.

It is, coldly viewed, a solution of mechanical scalability. And it is part of the explanation of why this tradition reached two billion, and others, with stricter dependence on the quality of the teacher, did not.

10. The consequence: matter as channel, and the partial retreat

The position

Put together chapters 1 and 6–9:

If the god took matter, matter can carry. Therefore water, oil, bread, hands, and bones are not reminders. They are channels.

From this follows almost all Western material piety: images and statues, relics, pilgrimages to places, blessed objects, holy water, miraculous images.

And art follows. The West produced an enormous tradition of representation of the human body — nude, suffering, dead, resurrecting — for theological reasons. That Renaissance anatomical study developed inside an ecclesiastical system of commissions is no coincidence.

The retreat

And then, in the 16th century, a large part of the tradition took this position back.

The Reformation, in its branches, reduced the sacraments to two, rejected relics, destroyed images, abolished pilgrimages, and replaced material mediation with text and preaching.

This is one of the most radical internal revisions I recorded in the entire series. It is not external criticism; it is the tradition disagreeing with itself over whether matter carries.

And the honest assessment

The Reformation objection was not abstract. Chapter 20 shows what the relic system had become: trade, forgery, trafficking in indulgences. The objections had empirical support.

And the cost of the retreat was also real: a tradition founded on the claim that the god took a body ended up, in large sections of itself, in a practice chiefly verbal — preaching, reading, hymn.

Part G of this text is, read this way, the return of the body through the back door: the Pentecostal practice, which was born within the Protestant world and is the most bodily Christian practice of the 20th century.
