The Passions and the Ascetic Vocabulary: Reference Guide
A working glossary, with theological depth, of the technical vocabulary of Orthodox ascetic theology: nous, kardia, logismoi, pathe, nepsis, diakrisis, plane/prelest, apatheia, and the terms that cluster around them. Every term is given with its Greek — and, where the Russian tradition carries it differently, with its Slavonic and Russian forms — together with a definition, the authors who use it, what it does not mean, and where in this repository the matter is treated at length. This collection treats these words as a vocabulary; the anthology in which most of them were transmitted is treated as a book at The Philokalia, and this guide defers to it.
Tradition: Pan-Orthodox
Why This Collection Exists
Orthodox ascetic literature is written in a technical language. It is not a devotional idiom that can be paraphrased into general religious English without loss; it is a precise vocabulary developed over a thousand years by writers who were describing something they expected their readers to be doing, and who used their words with the exactness of physicians. When St. John Climacus distinguishes provocation from coupling from assent, he is not decorating a moral exhortation — he is making a diagnostic distinction on which a practical judgment depends. When St. Maximus says that apatheia begets love, he is not recommending emotional flatness. When the Philokalia speaks of the nous descending into the heart, it is not describing a feat of concentration.
Most modern readers meet this vocabulary in translation, in fragments, and without a glossary. The result is predictable: passion is read as emotion, dispassion as apathy, intellect as reason, thoughts as ideas, watchfulness as mindfulness, discernment as good judgment, and delusion as being mistaken. Each of these misreadings is not merely imprecise; each inverts the term. This guide exists to supply the definitions and the guardrails.
It is written for three kinds of use. For the reader working through the Philokalia, the Ladder, St. Isaac, or St. Ignatius Brianchaninov, it is a reference to consult when a word stops making sense. For the priest or catechist, it supplies the distinctions that have to be made when this literature is handed to someone who is enthusiastic about it — the concern of Cautions for the Modern Reader. For a machine-loadable knowledge base, each file is self-contained: a single file can be loaded to establish the meaning of a single family of terms.
What Is Deferred
This is a glossary, not a history and not a manual. It systematically defers:
- The Philokalia as a book — its compilers, editions, and transmission from Venice 1782 to the Slavonic and Russian Dobrotolyubie and the modern English — to The Philokalia.
- The Jesus Prayer as a practice — its words, degrees, prayer rope, and psychosomatic method — to The Jesus Prayer and the hub article The Jesus Prayer.
- The desert milieu — Nitria, Kellia, Scetis, the Apophthegmata — to The Desert Fathers.
- The Ladder as a text to St. John Climacus.
- The dogmatic settlement of hesychasm — the essence–energies distinction and the councils of 1341–1351 — to St. Gregory Palamas and Theosis.
- Spiritual fatherhood to the hub article Spiritual Direction and to The Optina Elders.
Where those collections have taken a position, this one agrees with it and does not restate it differently.

How to Use This Guide
- To look up a word: go straight to The Terms and Their Greek, which carries the master table and points to the file that treats each term.
- Before trusting anything here: read The Sources and Their Limits. The vocabulary has a condemned author at its head, a pseudonymous corpus near its centre, and a standard English translation whose rendering of nous misleads almost every new reader.
- Before applying anything here: read Cautions for the Modern Reader. This is a monastic literature and it is routinely misapplied.
- For study in order: 02 supplies the anthropology; 03 and 04 the pathology; 05 and 06 the therapy; 07 the characteristic failure mode; 08 the health that is aimed at; 09 the frame.

Sourcing and Methodology
This collection is governed by the repository METHODOLOGY.md. Three features shape it:
- Definitional precision is the deliverable. Where authors differ on a definition, the difference is stated rather than harmonized. Where a scheme (of stages, of eight thoughts, of three degrees) is one author’s and not the Church’s, it is labelled as such.
- Three source-critical problems are stated openly, not buried: the condemnation of Evagrius, the pseudonymity and Messalian entanglement of the Macarian corpus, and the translation problem in the standard English Philokalia. All three are set out in The Sources and Their Limits.
- Three questions are left open under METHODOLOGY §4.2 and are marked where they arise: the standing of Evagrius, the relation of the Macarian corpus to Messalianism (agreeing with St. Macarius the Great), and whether Christian apatheia is continuous with the Stoic term or a transformation of it.
Important Caveats
- AI-generated content. This guide was generated with AI assistance. Care has been taken to cite real sources accurately, but every claim should be checked against the primary editions before being relied upon for catechetical or academic purposes.
- A monastic literature. Almost every source quoted here was written by a monk for monks. The Church has always given it to laypeople as well, but with adaptation and under guidance — see Cautions for the Modern Reader.
- Not a diagnostic manual. The passions are not a taxonomy of mental illness, and nothing in this literature is a substitute for medical or psychiatric care.
- Not a substitute for the primary texts, for confession, or for catechesis under a priest.
