02 — The Commonitorium
The Commonitorium (or Commonitory), written at Lérins around 434 under the pseudonym Peregrinus, is the single work on which Vincent’s whole fame rests: a compact handbook teaching the Christian how to tell catholic truth from heresy by a rule that survives long after its occasion. This section sets out its purpose, structure, and lost second book, and the historical moment — the aftermath of the Council of Ephesus (431) and the Nestorian crisis — that called it forth.
Tradition: Pan-Orthodox (pre-Schism West; the canon of catholicity)
The Commonitorium is a “reminder” (the meaning of its title) that Vincent says he writes for his own use, that he may have at hand the means of discerning the true faith. From this modest, practical aim comes the most influential single formula in the literature of Tradition. This section reads the work as a whole — its two-book structure, the lost portion known only through Vincent’s own recapitulation, and its careful method — and locates it in time: not in a vacuum, but in the wake of Ephesus, with Nestorianism the living heresy against which the rule is sharpened.

| The Purpose and Structure | The Commonitorium of c. 434 as a handbook for discerning catholic truth from heresy: its title and stated aim, its two-book form, the lost second book known only through Vincent’s recapitulation, the pseudonym Peregrinus, and the architecture of its argument. |
| The Occasion After Ephesus | The historical moment: the Council of Ephesus (431), the condemnation of Nestorius, and the Christological crisis that gave the Commonitorium its concrete targets — and the question of how directly the work engages that crisis. |
