The one true God has revealed Himself as the eternally self-existent “I AM,” the Creator of heaven and earth and the Redeemer of mankind. He has further revealed Himself as embodying the principles of relationship and association as Father, Son and Holy Spirit (Deuteronomy 6:4; Isaiah 43:10,11; Matthew 28:19; Luke 3:22).
The terms “Trinity” and “persons” as related to the Godhead, while not found in the Scriptures, are words in harmony with Scripture, whereby we may convey to others our immediate understanding of the doctrine of Christ respecting the Being of God, as distinguished from “gods many and lords many.” We therefore may speak with propriety of the Lord our God who is One Lord, as a trinity or as one Being of three persons, and still be absolutely scriptural (Matthew 28:19; 2 Corinthians 13:14; John 14:16–17).
