Tertullian Biography

This early Christian author from Carthage is the first to produce an extensive corpus of Latin Christian literature. Revered as the "father of Latin Christianity" and the founder of Western theology, he advanced new theological concepts despite his conservative outlook. His most significant contribution was the formal exposition of Trinitarian theology, introducing the Latin term "trinitas" and the foundational phrase "three Persons, one Substance." Although initially considered heretical, his theological formulations were later embraced as Christian orthodoxy.
