The word ”trinity” is not found in the Bible. But neither are words or expressions like ”incarnation” or ”investigative judgment.” What is important is that the concept is there. The word itself was coined in the late second century by the Latin church father Tertullian. The doctrine of the Trinity developed as the early church encountered the Greco-Roman world and began to reflect on how best to explain the biblical message to a pagan world.
