That's a moronic argument.
The word "Bible" is not in the Bible. Does that nullify the Bible?
WRONG
Scripture clearly illustrates the Trinity . . .
John 1:1
In the beginning was the Word and the Word was with God and the word WAS God.
This shows us TWO things:
a) The Word (the distinct Person of the Son) was WITH God the Father.
b) The Word (the distinct Person of the Son) WAS God along WITH the Father.
We know that the “Word” is the Son, because John goes on I the next 17 verses to describe WHO the Word is. He also refers to Him as “the Light” (v. 4-9) and states the He became FLESH and is the Son of the Father (v. 14).
God says:
Rev. 1:8
“I am the Alpha and the Omega,” says the Lord God, “who is and who was and who is to come, the Almighty.”
Jesus Christ says:
Rev. 22:13
I am the Alpha and the Omega, the first and the last, the beginning and the end.”
The Father is God
Eph. 4:6, Psalm 68:5, Mal. 2:10, 2 Cor. 1:3-4, John 3:16, John 8:41, 1 Thess. 3:13
The Son is God
Isaiah 7:14, Isaiah 9:6, Matt. 4:7, John 1:1, John 1:3, John 8:58, John 10:30, John 14:9, John 20:28, 2 Corinthians 4:4, Phil. 2:6, Col. 2:9, 1 Tim. 3:16, Heb. 1:8, Titus 2:13
The Holy Spirit is God
John 14:16-18, Luke 12:10, 2 Cor. 3:17, 2 Cor. 13:5, John 14:23, Acts 5:3-4
John 14:16,26; 15:26; 16:7 – the Father and the Son send the Counselor, the Holy Spirit – Isaiah 9:6 – the Counselor is Mighty God.
