Tertullian (; Latin: Quintus Septimius Florens Tertullianus; c. 155 AD – c. 220 AD) was a prolific early Christian author from Carthage in the Roman province of Africa. He was the first Christian author to produce an extensive corpus of Latin Christian literature. He was an early Christian apologist and a polemicist against heresy, including contemporary Christian Gnosticism. Tertullian has been called "the father of Latin Christianity" and "the founder of Western theology".Tertullian originated new theological concepts and advanced the development of early Church doctrine. He is perhaps most famous for being the first writer in Latin known to use the term trinity (Latin: trinitas).However, Tertullian was never recognized as a saint by the Eastern or Western Catholic churches. Several of his teachings on issues such as the clear subordination of the Son and Spirit to the Father, as well as his condemnation of remarriage for widows and of fleeing from persecution, contradict the doctrines of these traditions, and his later rejection of orthodoxy for Montanism has led these communions to refrain from considering him a Church father, important ecclesiastical writer though he was.
