I believe in the one only and true God, who exists in the unity of the Godhead, each coeternal and coequal, the same in substance but distinct in subsistence. In addition, I believe that the term “trinity” is un-biblical but completely and undeniably Scriptural. What I mean by that is the word Trinity is not mentioned in the bible, but the irrefutable truth of the Trinity is clearly revealed and proven throughout it.
While developing a clear, all-encompassing, definition of the trinity has been a challenge for scholars and laymen alike for as long as the church has existed, the essential elements of any definition of the trinity are the oneness of God; the distinction of the God-head; and the deity of each within the God-head. Matthew 29:18 stands as the best scripture that expresses the existence of the trinity, “Go there fore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
Scriptures defining the trinity are:
Those verses establishing the oneness of God:
“Here O Israel: The LORD our God, the LORD is one. (Deuteronomy 6:4)”; “Therefore, as to the eating of food offered to idols, we know that ‘an idol has no real existence,’ and that ‘there is no God but one. (1 Corinthians 8:4)”; “Now an intermediary implies more than one, but God is one. (Galatians 3:20)”; “For there is one God, and there is one mediator between God and men, the man Christ Jesus. (1 Timothy 2:5)”.
Those verses establishing the plurality of God:
“In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. (Genesis 1:1-2)”; “Then God said, “Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth. (Genesis 1:26)”; “Then the Lord God said, “Behold, the man has become like one of us in knowing good and evil. Now, lest he reach out his hand and take also of the tree of life and eat, and live forever— (Genesis 3:22)”; “Come, let us go down and there confuse their language, so that they may not understand one another’s speech. (Genesis 11:7)”; “Thus says the LORD, the King of Israel and his Redeemer, the LORD of hosts: “I am the first and I am the last; besides me there is no god. (Isaiah 44:6)”
Those verses establishing the plurality as a trinity:
“Now there are varieties of gifts, but the same Spirit. And there are varieties of ministries, and the same Lord. There are varieties of effects, but the same God who works all things in all persons. (1 Corinthians 12:4-6)”; “The grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit, be with you all. (2 Corinthians 13:14)”; “Peter, an apostle of Jesus Christ, To God’s elect, exiles scattered throughout the provinces of Pontus, Galatia, Cappadocia, Asia and Bithynia, who have been chosen according to the foreknowledge of God the Father, through the sanctifying work of the Spirit, to be … (1 Peter 1:1-2)”; ““For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, because anyone who serves Christ in this way is pleasing to God and receives human approval. (Romans 14:17-18)”; “Draw near to me, hear this: from the beginning I have not spoken in secret, from the time it came to be I have been there. And now the Lord God has sent me, and his Spirit. (Isaiah 48:16)”; “And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; and behold, a voice from heaven said, ‘This is my beloved Son, with whom I am well pleased.’ (Matthew 3:16-17)”
Those verse establishing the distinction of each within the Godhead:
The Father is God: John 6:27; Romans 1:7; 1 Peter 1:2. The son is God: John 1:1, 1:14; Romans 9:5; Colossians 2:9; Hebrews 1:8; 1 John 5:20. The Holy Spirit is God: Acts 5:3-4; 1 Corinthians 3:16
