Quintus Septimius Florens Tertullianus; the first great Latin Christian writer. A North African of Carthage, trained in rhetoric and law; coined much of the Latin theological vocabulary the West later inherited (Trinitas, persona, substantia). His pre-Montanist works are widely cited and respected; his later embrace of the New Prophecy (Montanism) places him outside the catalogue of formally venerated saints, though he is treated honourably as a witness and theologian.
