For there are three that bear record in heaven,
the Father, the Word, and the Holy Ghost: and these three are one.
The Father is called God–
Romans 15:6 That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.
Jesus is called God
And without controversy great is the mystery of godliness: GOD WAS MANIFEST IN THE FLESH, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory. 1 Timothy 3:16
Hebrews 1:8 But unto the Son he [God] saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.
For in him [Jesus] dwelleth ALL the fulness of the Godhead bodily. Colossians 2:9
The Holy Ghost is called God–
Acts 5:3-4 But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land? …thou hast not lied unto men, but unto God.Each Person of the Godhead SPEAKS AUDIBLY in the Bible–
God the Father SAID of Jesus in Matthew 3:17 …”This is my beloved Son, in whom I am well pleased.”
Jesus SAID in John 10:30, ” I and my Father are one.”
The Holy Ghost SAID in Acts 13:2, …”Separate me Barnabas and Saul for the work whereunto I have called them.”
Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man\’s device. Acts 17:29For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: Romans 1:20For in him [Jesus] dwelleth all the fulness of the Godhead bodily. Collosians 2:9
