Vincent of Lérins
St. Vincent of Lérins was a fifth-century ecclesiastical writer based in Southern Gaul.
Nearly all known biographical details derive from Gennadius' De viris illustribus.
He entered the renowned monastery of Lérins, located on what is today the Isle St. Honorat, where he devoted himself to monastic life and theological scholarship.
In 434, he authored his celebrated Commonitorium, publishing it under the pseudonym Peregrinus, meaning "pilgrim." The work became foundational in Christian theological tradition, particularly for its articulation of the rule of universality, antiquity, and consent as the standard for identifying authentic doctrine.
