The Nature of God / Trinity

Matthew 28:19, John 14:16-17, 2 Corinthians 13:14

The Position

Father, Son, and Holy Spirit — three persons, one God. The Father and the risen Christ are in heaven. The Holy Spirit is on earth with and in believers now.

The Study

## Core Position

God is one Being existing eternally as three distinct, simultaneous persons — Father, Son, and Holy Spirit. Each person is fully God. The Trinity is not three separate gods, nor one person wearing three sequential masks. This is the foundational nature of God, and humanity is made in that triune image.

The mystery of the Trinity is answered by faith. Faith is the only means by which a person accepts something that exceeds rational thought. The Trinity does not violate reason — it exceeds reason's ceiling. The born-again spirit receives this truth; the renewed mind comes into agreement with it. This is consistent with Hebrews 11:6 — "Without faith it is impossible to please God."

Supporting Scripture

Matthew 3:16-17 — All three persons present simultaneously at Jesus's baptism: the Son is baptized, the Spirit descends as a dove, the Father speaks from heaven. Three distinct persons, one event.

John 10:30"I and the Father are one." Unity of being, not identity of person.

John 14:16"I will ask the Father, and he will give you another Helper." Three distinct persons named in one sentence by Jesus himself.

Matthew 28:19"Baptize in the name (singular) of the Father and of the Son and of the Holy Spirit." One name, three persons.

Genesis 1:26"Let us make man in our image." Plural persons within one Godhead — foundational to all Trinitarian understanding.

Acts 7:55-56 — Stephen sees the Son standing at the right hand of the Father — two distinct persons simultaneously visible in the spiritual realm.

2 Corinthians 13:14 — Grace, love, and fellowship attributed distinctly and simultaneously to Son, Father, and Spirit.

Current Location of Each Person

The Father — Enthroned in heaven (Matthew 6:9, Revelation 4).
The Son — Bodily at the right hand of the Father in the spiritual realm, resurrection body intact (Hebrews 1:3, Acts 7:55-56, Acts 1:9-11).
The Holy Spirit — Passed through the veil from the spiritual realm into the physical realm at Pentecost. Presently with us and in us (John 14:16-18, Acts 2:1-4).

On the Holy Spirit's Omnipresence

The Spirit is God and therefore omnipresent by nature (Psalm 139:7-8). But manifest presence is distinct from omnipresence. Jesus said "it is to your advantage that I go, so that the Helper may come" (John 16:7) — indicating a deliberate, purposeful sending of the Spirit into the physical realm to be with and in believers in a way not previously available. The Spirit's presence here is not a reduction of omnipresence but a specific mission assignment — the same pattern by which the Son came to earth without vacating heaven.

Faith as the Answer to the Mystery

The precise mechanics of how three distinct persons constitute one divine being exceeds full rational comprehension in this life. This is not irrationality — it is the limit of creaturely understanding before infinite being.

Faith = spiritual understanding. The born-again spirit already knows and receives the truth of the Trinity.
Belief = mental understanding. The renewed mind comes into agreement with what the spirit already holds.

When faith and belief agree, the Trinity is not merely a doctrine to be defended but a reality to be lived inside of — as sons and daughters of the Father, in union with the Son, indwelt by the Spirit.

"Without faith it is impossible to please God." — Hebrews 11:6

What This Rejects

Modalism / Oneness Pentecostalism — one person in three sequential modes. Rejected: three persons are simultaneously distinct (Matthew 3:16-17).
Tritheism — three separate gods. Rejected: one God, one divine being (Deuteronomy 6:4, John 10:30).
Arianism — the Son as a created being lesser than the Father. Rejected: Jesus is fully God (John 1:1, John 8:58, Colossians 2:9).
Subordinationism — the Spirit as lesser than Father or Son. Rejected: all three are equally God (2 Corinthians 13:14).

The Evidence

Byzantine Art

IC XC = Iēsous Christos. NIKA = conquers. One civilization's confession in four letters: Jesus Christ conquers. The Trinitarian theology was woven into the art before it was systematized in Western theology.
