The gospel of the Bible is a trinitarian gospel. It proclaims Father, Son and Holy Spirit; three persons existing in one Godhead. This truth forms the foundation of Christian faith and the knowledge of it is based upon the revelation God has given in His word. The Westminster Confession of 1646 states:
'In the unity of the Godhead there be three persons, of one substance, power, and eternity: God the Father, God the Son, and God the Holy Ghost...'
Godhead refers to the divine nature. The English word Godhead is found three times in the King James Bible and has been used by the translators to express the being (Acts 17:29), nature (Romans 1:20) and attributes (Colossians 2:9) of deity. We as humans possess a human nature, we are part of humanity. The three persons of the Godhead posses a divine nature and each share the attributes of deity.
