The document discusses the biblical doctrine of the Godhead or Trinity. It explains that the Bible teaches there is one God but that God exists as three distinct persons - Father, Son and Holy Spirit. Each person is fully God yet distinct from one another. The document provides many biblical examples and passages to support this view, such as Jesus being present at creation in Ephesians 3:9 and God using "us" in Genesis when deciding to create man. It also discusses attributes like omnipresence, omnipotence, and holiness that are shared by all three persons of the Godhead.
