The Foundation of the Apostolic Faith
"Hear, O Israel: The LORD our God, the LORD is one." Deuteronomy 6:4
A Question Worth Asking
For many Christians, the word "Trinity" is assumed to be part of the original teaching of the early church. But when we go back to the Bible, the true foundation of our faith, we discover something surprising and powerful:
The doctrine of One God, revealed fully in Jesus Christ, was taught long before the idea of a Trinity was ever introduced.
Scripture First
God didn't say He was part of a Trinity. He said He was alone, that He formed the heavens by Himself, and that He is the only Savior.
"Hear, O Israel: The LORD our God, the LORD is one!"
The Shema, the foundational confession of all Scripture. One God. Not three.
"I am the LORD, and there is no other; there is no God besides Me."
God declares His absolute singularity. No second person. No third person. None beside Him.
"Before me there was no God formed, neither shall there be after me."
There was no God before Him and no God after. He has always been and will always be alone as God.
"I am the First and I am the Last; besides Me there is no God."
The Alpha and Omega. The First and the Last. Besides Him, no God exists. Period.
"And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace."
The Son born to us is called the Everlasting Father, not a separate person from the Father.
"Yet for us there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ."
Paul confirms it. One God. One Lord. Not a divided Godhead, one.
Jesus Revealed the One True God
They preached Jesus as the name above every name and baptized in His name. Every scripture below points to the same conclusion: Jesus is not one-third of God. He is God.
"For in Him dwells all the fullness of the Godhead bodily."
ALL the fullness. Not a third. Not a portion. Every bit of what God is lives in Jesus Christ, bodily.
"I and My Father are one."
Jesus said it plainly. The religious leaders understood it, they picked up stones to stone Him for claiming to be God.
"He who has seen Me has seen the Father."
Not a representative of the Father. Not a son who looks like the Father. To see Jesus is to see God.
"God was manifested in the flesh, justified in the Spirit, seen by angels, preached among the Gentiles, believed on in the world, received up in glory."
God, not a Son of God, not a second person, GOD HIMSELF was manifested in flesh. That is Jesus.
"In the beginning was the Word, and the Word was with God, and the Word was God… And the Word became flesh and dwelt among us."
The Word was not a second God beside God, the Word WAS God. And that Word became flesh in Jesus Christ.
"God also has highly exalted Him and given Him the name which is above every name."
One name. Above every name. That name, the name given by God, is Jesus.
A Biblical Oneness Study
Instead of starting with scattered proof texts, Scripture gives us a clear flow: there is one God, that one God is Spirit, Creator, Savior, and Father, and that one God revealed Himself in flesh in Jesus Christ.
The foundation of Apostolic doctrine is biblical monotheism. Scripture does not begin with three divine persons. It begins with one God.
Before we define Jesus' titles, we must first define God biblically. The God of Scripture is one, alone in creation, alone as Savior, and without another beside Him. This is the starting point that makes everything else clear.
The one God is not one member of a divine committee. He is the eternal Spirit, the invisible God, the only Creator, the only Savior, and the Father of all.
Scripture identifies the one God as Spirit and invisible, yet also as the only Creator and the only Savior. This matters because the New Testament reveals that this same invisible God made Himself known in Jesus Christ, the visible image of the invisible God (Colossians 1:15).
The incarnation is the mystery of godliness: the one God revealed Himself in real human flesh. Jesus is not merely a man close to God, and He is not a second divine person beside the Father. Jesus Christ is God manifested in flesh. The fullness of the Godhead dwells in Him bodily.
Mini Study: 1 Timothy 3:16 and Colossians 2:9
1 Timothy 3:16 says God was "manifest in the flesh." The word manifest means revealed, made visible, or made known. The invisible God was revealed in true humanity.
Colossians 2:9 says, "For in Him dwells all the fullness of the Godhead bodily." Paul does not say part of God, one-third of God, or a lesser divine being. He says all the fullness of deity dwells in Christ bodily.
The titles Jesus, Christ, Son of God, Son of Man, and Lord do not describe multiple divine persons. They reveal different aspects of the same one Lord Jesus Christ.
The personal name of the Savior
His saving mission and real human life
Matthew 1:21 · Luke 1:31
Messiah, the Anointed One
His prophetic, priestly, kingly, and redemptive role
John 20:31 · Acts 2:36
The holy one born through the work of the Spirit
The incarnation; God revealed in flesh
Luke 1:35 · Romans 1:3-4
The true man and promised ruler
His humanity, suffering, authority, and kingdom
Daniel 7:13-14 · Mark 2:10
Master, ruler, and divine title
His divine authority and identity as God
Romans 10:9-13 · Philippians 2:9-11
Jesus bears God's titles, does God's works, receives divine honor, and fulfills Old Testament passages written about the LORD. This is not coincidence. It is the consistent testimony of the entire New Testament.
The Oneness Message in One Statement
The Oneness message is not that Jesus is merely another name beside God. It is that the one God of Scripture revealed Himself in Jesus Christ. The Father was revealed in the Son. The invisible God became visible in the man Christ Jesus. Jesus Christ is the fullness of God manifested bodily. He is not a second divine person. He is God manifest in flesh, crucified and risen, and worthy of all worship, all obedience, and all authority in heaven and on earth.
An Honest Question
The word "Trinity" is not found anywhere in the Bible. Jesus never used it. The apostles never used it. Here is where it actually came from.
The first Christian writer to use the Latin word Trinitas was Tertullian, a North African theologian who blended Scripture with Roman and Greek philosophical language. The word does not appear in Scripture, it was a theological term invented to describe a concept that would be debated and defined for centuries.
Emperor Constantine called the Council of Nicaea to settle theological disputes that were fracturing his empire. Bishops were brought together under imperial pressure and the Nicene Creed was adopted, declaring the Son to be "of one substance (homoousios) with the Father," affirming His co-eternity. This was not a decision made by the apostles. It was made by a council, under a Roman emperor, three centuries after Pentecost.
The Holy Spirit was formally declared the third co-equal person of the Trinity. The full Trinitarian doctrine, Father, Son, and Holy Spirit as three distinct, co-equal, co-eternal persons, was now official imperial church doctrine. What the apostles never taught in Scripture had been decided by councils over 350 years after Pentecost.
The full Trinitarian doctrine became official Catholic dogma and flowed into virtually every Protestant denomination through the Reformation, which challenged the authority of Rome but retained its Trinitarian framework. Most of Christianity today inherited this doctrine not from the apostles but from fourth-century imperial councils.
The Apostolic pattern that began at Pentecost, Spirit baptism with the evidence of tongues and baptism in Jesus' name, was restored in fullness at the Azusa Street Revival. What God established in Acts 2 has never truly stopped. It was always there, always alive, always producing the same results in those who fully obeyed.
The Point of It All
God never meant for us to be confused about who He is. From Genesis to Revelation, the Bible reveals a singular, sovereign God who robed Himself in flesh to save us.
If Jesus is the fullness of the Godhead bodily, then baptism in His name is baptism in the name of the Father, Son, and Holy Spirit, because Jesus IS that name. Matthew 28:19 says "the name" (singular). Acts 2:38, 8:16, 10:48, and 19:5 all show what that name is: Jesus.
When God is One, the new birth of John 3:5, born of water and Spirit, is a single experience with one God. Water baptism in Jesus' name and the Holy Spirit are not two gods, they are two aspects of receiving the one God who is Jesus Christ.
Jesus said "Whatever you ask in My name, that I will do" (John 14:13). Not in three names. Not through a three-person committee. The name of Jesus carries all the authority of heaven because in Him dwells all the fullness of the Godhead bodily.
Acts 4:12, "There is no other name under heaven given among men by which we must be saved." Not a formula of three titles. One name. The name of the One God who became flesh, died for our sins, and rose from the dead. That name is Jesus.
The Conclusion of the Matter
"The doctrine of Oneness didn't come later, it came first. It was taught by Moses, revealed by Jesus, and preached by the apostles. We don't need man-made creeds. We need Jesus. We don't need philosophical terms. We need the name that is above every name. And that name is Jesus."
Colossians 2:9 • Acts 2:38 • Philippians 2:9
History in Context
Some confuse the political establishment of Christianity with the spiritual birth of the church. These are not the same event, and the difference matters enormously.
| Pentecost (Acts 2) | Theodosius (AD 380) |
|---|---|
| Spiritual, grassroots beginning | Political, top-down decree |
| Empowered by the Holy Spirit | Enforced by imperial law |
| Salvation by repentance, baptism, Spirit (Acts 2:38) | Membership often became cultural or compulsory |
| Led by apostles and early believers | Controlled by emperors and bishops |
The church began at Pentecost, not under Theodosius. Theodosius didn't found the church; he made it the state religion. That is a political milestone, not a spiritual birth. Some historians and commentators conflate the two, but they are separated by nearly 350 years and are entirely different in nature.
Comparing the Views
The Apostolic position is rooted in Peter's own words in Acts. Here is what the early record shows, and how the Trinitarian doctrine developed later.
Peter's preaching was laser-focused on Jesus as the revelation of the one true God. His words in Acts are the clearest window we have into Apostolic doctrine:
"God has made this Jesus, whom you crucified, both Lord and Christ."
"Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit."
"Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved."
Peter and the Apostles centered their message on Jesus' identity as the full revelation of God, not on a later theological term like "Trinity." Their framework was strictly Jewish monotheism, fulfilled and unveiled in the person of Jesus Christ.
The Apostolic (Oneness) position holds that God is absolutely one, not a Trinity of three persons, but one God who revealed Himself fully in Jesus Christ:
Trinitarians believe in one God eternally existing as three co-equal, co-eternal persons: Father, Son, and Holy Spirit. For context and accuracy, here is the Trinitarian position:
