The Christian doctrine of the Trinity is best expressed as the statement that the one God exists in three equally divine “beings”. These being the Father, the Son, and the Holy Spirit. It is important to understand that they are not three individuals but instead three forms in which the Divine Being exists. Each is divine but they are not three separate gods, combined they are one God. The doctrine of the Trinity includes a strict monotheism in which in all of the universe a single being known as God exists (Isaiah 43:10). This paper will outline the development of the Christian doctrine of the Trinity from the New Testament Church to the Nicene Creed.
