While the word “Trinity” never appears explicitly in the text, the doctrine is built systematically on three Biblical premises: there is only one God, the Father, Son, and Holy Spirit are distinct persons, and each person is fully God.
Below are the key scriptures categorized by how they support the triune nature of God.
Passages Mentioning All Three Persons Together
- Matthew 28:19 “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit…” (Notice “name” is singular, reflecting one God in three persons).
- Matthew 3:16 17 “And when Jesus was baptized… 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.’”
- 2 Corinthians 13:14 “The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all.”
- Ephesians 4:4 6 “There is one body and one Spirit… one Lord, one faith, one baptism, one God and Father of all…”
- 1 Peter 1:2 “…according to the foreknowledge of God the Father, in the sanctification of the Spirit, for obedience to Jesus Christ…”
- 1 John 5:7 (KJV/NKJV) “For there are three that bear record in heaven: the Father, the Word, and the Holy Ghost: and these three are one.” (Note: Textual scholarship notes this verse, known as the Johannine Comma, is absent from the earliest Greek manuscripts).

The Deity and Personhood of the Holy Spirit

- 1 Corinthians 3:16 “Do you not know that you are God’s temple and that God’s Spirit dwells in you?”
- 1 Corinthians 2:10 11 “…For the Spirit searches everything, even the depths of God… So also no one comprehends the thoughts of God except the Spirit of God.”
- John 14:16 17, 26 “And I will ask the Father, and he will give you another Helper… the Holy Spirit, whom the Father will send in my name, he will teach you all things…”
The Plurality of God in the Old Testament
