Why Christians Believe in the Trinity

by Peter Ditzel

So that we know what we are talking about, let’s begin with a definition. A basic formulation of the Trinity doctrine is, God is a Trinity of three Persons—the Father, the Son, and the Holy Spirit, and these three are one God, the same in substance, equal in power and glory. Many who teach against the Trinity misunderstand this formula. They make a wrong assumption about what is meant by God being a Trinity of three Persons. They assume this to be tritheism, a belief in three gods. What is meant by “Person” in speaking of the Trinity is that which has the attributes of personality. It comes from the Latin word persona. In the ancient world, actors wore masks. The actor’s mask was his persona. It showed the role he was playing. In the discussion of the Trinity, “Person” never means “person” as we commonly use it today; that is, it never means a free and independent consciousness with his own will. Nevertheless, it does mean that the Persons have an I-you relationship: as I will point out in the Scriptures cited in this article, they communicate with each other.
