The Trinity

"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."

— Matthew 28:19 (ESV)

1. God the Father

Creator, Sustainer, Sovereign Lord
Who He Is: The first person of the Trinity — the eternal, all-powerful Creator and loving Father. He is holy, just, merciful, and sovereign over all things. He initiates the plan of salvation and sends the Son and Spirit.

Key Attributes: Sovereignty, holiness, love, faithfulness, omniscience.

Common Misconception: That the Father is the "real" God and the Son/Spirit are lesser — all three persons are equally and fully God.
Key Scriptures:
Isaiah 64:8
John 3:16
Ephesians 1:3-6
James 1:17

2. God the Son

Eternal Word, Incarnate Savior, Risen Lord
Who He Is: The second person of the Trinity — the eternal Son who became flesh (John 1:14). Fully God and fully man, He lived perfectly, died substitutionally, rose bodily, and now reigns at the Father's right hand.

Key Attributes: Deity, humanity, sinlessness, sacrificial love, authority.

Common Misconception: That Jesus became God's Son at His baptism or was created — He is eternally begotten, not made (Nicene Creed).
Key Scriptures:
John 1:1-3, 14
Colossians 1:15-20
Philippians 2:5-11
Hebrews 1:1-3

3. God the Holy Spirit

Comforter, Counselor, Spirit of Truth
Who He Is: The third person of the Trinity — not an impersonal force but a divine Person who convicts, regenerates, indwells, empowers, and guides believers. He applies the work of Christ to our lives and produces spiritual fruit.

Key Attributes: Personhood, deity, power, holiness, gifts.

Common Misconception: That the Spirit is merely a force or influence — He has intellect (1 Cor 2:10-11), will (1 Cor 12:11), and emotions (Eph 4:30).
Key Scriptures:
John 14:16-17, 26
Acts 1:8
Romans 8:14-16
Galatians 5:22-23

4. Trinity in the Old Testament

Hints, shadows, and plural references
What We See: While not fully revealed, the OT contains significant hints of plurality within God: the plural "Elohim" with singular verbs, "Let us make man" (Gen 1:26), the Angel of the LORD who speaks as God, the Spirit of God hovering (Gen 1:2), and Wisdom personified (Prov 8).

Common Misconception: That the Trinity is a NT invention — the seeds are clearly present in the OT, awaiting fuller revelation.
Key Scriptures:
Genesis 1:1-2, 26
Isaiah 48:16
Isaiah 63:9-10
Psalm 110:1

5. Trinity in the New Testament

Clear revelation of three persons, one God
What We See: The NT makes explicit what the OT implied. At Jesus' baptism, all three persons appear simultaneously (Matt 3:16-17). The Great Commission names all three. Paul's benedictions invoke all three. The apostles teach one God in three persons without contradiction.

Common Misconception: That "Trinity" must appear in the Bible to be valid — the word is not there, but the reality is on every page of the NT.
Key Scriptures:
Matthew 3:16-17
Matthew 28:19
2 Corinthians 13:14
1 Peter 1:2

6. How They Work Together

United in purpose: creation, salvation, sanctification
What We See: The three persons work in perfect harmony: the Father plans, the Son accomplishes, the Spirit applies. In creation: Father speaks, Son is the agent (Col 1:16), Spirit gives life (Gen 1:2). In salvation: Father sends, Son dies, Spirit regenerates. In sanctification: Father disciplines, Son intercedes, Spirit empowers.

Common Misconception: That the persons take turns or have separate agendas — they always act in unified purpose and mutual love.
Key Scriptures:
Ephesians 1:3-14
John 16:13-15
Romans 8:26-30
Titus 3:4-6
