Tertullian was an early Christian theologian and apologist born around 155 AD in Carthage, North Africa. He is best known for his significant contributions to Christian doctrine, particularly his writings on the Trinity and the nature of Christ, as well as for coining terms such as "Trinity" and "Christian." Tertullian's works laid the groundwork for later Christian thought and he is often regarded as one of the founding fathers of Western theology.
