Early Theologians
Apology, Prescription Against Heretics & Against Praxeas
Tertullian of Carthage · c. 197 – 220
Historical Context
A North African convert trained in rhetoric, Tertullian was the first major Christian writer in Latin and coined much of the vocabulary later used by Western theology.
Summary
He defends Christians before Roman authorities, argues that heretics have no right to appeal to the Scriptures of the Church, and gives the Latin West its first formal Trinitarian language ('one substance, three persons'). His later turn to the Montanist movement complicated his legacy.
