Incarnation, Eucharist and the Christian Body: A Complete Guide

How to read this text

You need no prior knowledge. Every term is explained the first time it appears.

Six honest notes before we start

First: why the title is not “The Body as Temple”

It is the obvious choice, and it is wrong.

“The temple of the Spirit” is a Pauline image, true and secondary: it says the body houses something precious. That is said, in various forms, by almost every tradition in this series.

The claim that makes this tradition structurally unique is a different one, and far more extreme:

Matter is not the vehicle of salvation. It is its object.

The god took a body. The hope is resurrection of the body, not immortality of the soul. The central mystery is to eat a body. And the bones of the dead remain holy.

None of the thirteen previous texts in this series claims anything of the sort. Most of the traditions I examined treat the body as vehicle, map, debt, garment or obstacle. Here it is the material.

Second: what this text does not cover

The hesychast tradition. The prayer of the heart, the Philokalia, the placing of the mind in the heart, plane (“delusion”) as a diagnostic category — all covered in the Greek guide of this series, and I will not repeat them.

This text concerns the Western, incarnational line: the Latin West and its global descendants.

The distinction is operational, not clean. Augustine is shared. The seven Ecumenical Councils are shared. The eucharist is shared, with different theology. Where the line blurs, I mark it.

Third: I do not defend and I do not refute

The text describes what is done with the body and what its logic is. It does not judge whether the god took a body; this is not a question the instruments of this text can touch.

It judges only what is critical: datings, historical events, and claims that were made as empirical.

Where there is internal disagreement — and here there is more than anywhere else in the series, because this tradition split repeatedly on exactly these questions — I record it rather than take a side.

Fourth: 2.4 billion living people, and many of them near you

Writing about the Nahua, you describe a world that ended. Here, the object answers back — and in many European countries the object is, for many readers, their own home.

This does not change the criterion. The same measure I applied to bloodletting, to human sacrifice, to child-witchcraft accusations and to Tibetan abuse, applies here too, in chapters 23–24 and 27. A series that bends on the last document is worth nothing.

Fifth: this is a doctrinal system, and the difference matters

The Islamic document stood apart from the previous ones because the system was normative: it does not tell you how the body works, it tells you what you owe to do with it.

This one is the third kind. It is doctrinal: its central content is a set of claims about what is true regarding a specific body at a specific time — and the bodily practice follows from them.

That is why Part A is theoretical. You cannot understand why bread is eaten or why bones are kept without the claim that produces them.

Sixth: where there are actually data

Twice in this text there are measurements, and you will see them marked: in chapter 14 (chant and breath) and chapter 26 (glossolalia).

Everywhere else I speak of history, texts and institutions. I will not disguise one as the other.

A short introduction to Christian thought, for the reader who is new

Before any of the technical material lands, four things to hold.

Where this comes from, in time and place

The textual tradition reaches back to the Hebrew Bible (c. 1200–200 BCE in its final redaction), from which this tradition inherits its anthropology; its own founding texts — the New Testament — were written in Koinē Greek between roughly 50 and 110 CE. The institutional form this guide describes was shaped in two long arcs: the patristic period (c. 100–750 CE), which produced the Councils, the Creed, and the great Latin and Greek Fathers (Augustine, c. 400; John of Damascus, c. 750); and the Latin medieval and early modern period (c. 1050–1700), which produced the sacramental system, the mendicant and monastic orders, the scholastic synthesis of Aquinas, and the fracture of the Reformation.

Today there are approximately 2.4 billion Christians worldwide — around one-third of humanity. The main divisions, by numbers: Roman Catholic (c. 1.3 billion), Protestant and Independent (c. 900 million, extremely heterogeneous), Eastern Orthodox (c. 220 million), Oriental Orthodox (the non-Chalcedonian churches — Coptic, Syriac, Armenian, Ethiopian; c. 60 million). The centre of gravity has shifted sharply south over the twentieth century: in 1910 roughly two-thirds of Christians lived in Europe; today roughly two-thirds live in Africa, Asia, and Latin America.

There is no “the” Christian tradition

This guide uses the Latin Western line as its backbone and marks where the Eastern lineages diverge. Where a position is dogmatic across the whole tradition (chapter 4 on resurrection, for instance), I say so; where it is distinctively Western (transubstantiation, 1215; the seven sacraments as a fixed list, 12th c.), I date it.

What kind of body-knowledge this is

The body material in this guide comes from four kinds of source:

• The founding texts — the Hebrew Bible, the New Testament, especially the Pauline letters, John 1 and 6, and 1 Corinthians 15
• The patristic corpus — the Councils, the Creed, Augustine, Gregory of Nazianzus, Thomas Aquinas, the medieval scholastics
• The practical rules and manuals — the Rule of Benedict (c. 530), the Liturgy of the Hours, Ignatius’ Spiritual Exercises (1548), the sacramental law
• Modern historical and clinical scholarship, including the archaeology of relics, the quantitative studies of chant and prayer, and the pediatric literature on faith-healing deaths

What this material is not

It is not above internal criticism. Chapter 24 covers the body of others — torture as institution, witch-prosecutions, judicial corporal punishment — without softening. Chapter 23 covers the self-starvation of medieval women ascetics without romance. Chapter 27 covers the children who died in the 20th and 21st centuries from treatable conditions in faith-healing communities. These are not footnotes; they are the chapter the governing rule of this series requires.

It is not continuous. The tradition revised itself radically — in the sixteenth century, large portions of it rejected the sacramental materialism of chapters 6–10 and moved to text and preaching. Chapter 10 is explicit about this.
