Quintus Septimius Florens Tertullianus, known as Tertullian, was a prolific early Christian author and theologian from Carthage in the Roman province of Africa. One of the first major Christian writers to compose in Latin, he earned the title "Father of Latin Christianity" for his profound influence on Western theology. His works, including "Apologeticus," "De Praescriptione Haereticorum," and "Adversus Marcionem," vigorously defended the Christian faith and shaped orthodox doctrine. Later in life, Tertullian joined the Montanist movement. His sharp intellect, rhetorical brilliance, and theological innovations left an enduring legacy on the early Church.
