The word "Trinity" is never used, nor is the doctrine of Trinitarianism ever explicitly taught in the Scriptures, but Trinitarianism is the best explanation of the biblical evidence. The theological exposition of the doctrine arose from clear…scriptural teaching. It is a crucial doctrine for Christianity because it focuses on who God is, and particularly on the deity of Jesus Christ. Because Trinitarianism is not taught explicitly in the Scriptures, the study of the doctrine is an exercise in putting together biblical themes and data through a systematic theological study and through looking at the historical development of the present orthodox view of what the biblical presentation of the Trinity is.
