Christadelphianism
Short answer: Christadelphianism is a restorationist movement that denies the Trinity and teaches that Jesus is a created, sinless man, while the Father alone is God. Its key proof text, John 14:28, says, “for the Father is greater than I.” The verse does not say Jesus is less than divine in nature; it speaks of his mission as the sent Son who was returning to the Father. Scripture also calls Jesus the Word who was God (John 1:1), the exact image of the invisible God (Colossians 1:15), and the one in whom all the fullness of deity dwells (Colossians 1:19). Christadelphians are sincere, but their reading of John 14:28 is selective. Faithful Christians have always seen in these texts one God in three persons, not one God and a glorified man.
Who the Christadelphians Are and What They Teach
Christadelphianism began in the mid-nineteenth century in the United States, associated with John Thomas, an English-born doctor who emigrated and later wrote extensively on what he believed was the true apostolic faith. The name Christadelphian means brothers of Christ, and members typically call themselves brothers and sisters. They meet in ecclesias rather than churches and have no central headquarters. Their beliefs are summarized in documents such as the Birmingham Amended Statement of Faith.
Three convictions mark the movement. First, God is one person, the Father, not a Trinity. Second, Jesus is a created human being, sinless by God's grace and the virgin birth, but not God incarnate. Third, the Holy Spirit is God's power or presence, not a distinct person. Christadelphians also believe the kingdom of God will be established on earth at Christ's return, with believers raised to reign with him, while the wicked are destroyed rather than endlessly tormented.
This is not a minor doctrinal difference. If Jesus is not truly God, then the atonement is not the sacrifice of God himself for sin, worship of Jesus is idolatry, and the gospel is fundamentally altered. Christians must therefore examine the Scriptures carefully, especially the texts Christadelphians use most often, including John 14:28.
What John 14:28 Actually Says and Does Not Say
The verse reads, “You heard how I told you, ‘I go away, and I come to you.’ If you loved me, you would have rejoiced, because I said ‘I am going to my Father;’ for the Father is greater than I.” Notice the setting. Jesus is speaking to his disciples on the night he was betrayed. He is preparing them for his departure, his death, resurrection, and ascension. The statement about the Father being greater is given as a reason for joy, not as a lesson in metaphysics.
If Jesus had meant he was a created being and not God, the flow of the sentence would be strange. He tells them he is going to the Father, and that this should make them glad. The reason given is that the Father is greater. In context, Jesus is the sent one returning to the one who sent him. He is not comparing divine natures and reporting that his is inferior.
Scripture consistently presents the Son as equal in nature and subordinate in mission. Philippians 2:5-11 describes the mind of Christ, who existed in God's form yet humbled himself and became obedient to death. That passage does not describe a creature becoming obedient; it describes the eternal Son taking on servant form. John 14:28 fits that pattern.
The Father Is Greater: Mission, Not Nature
Throughout the Gospel of John, Jesus speaks of being sent by the Father. He says he can do nothing on his own, that he speaks what the Father commands, and that he came down from heaven to do the Father's will. These statements express the Son's willing submission in the work of redemption. They do not measure the Son's essence against the Father's.
Suppose a king sends his son to represent him. The son may say, “The king is greater than I,” meaning greater in position and authority within the mission. No one would conclude the son is not truly the king's son or not of the same nature. Similarly, Jesus, during his earthly mission, lived in dependence on the Father and spoke of the Father as greater in the economy of salvation.
This distinction between nature and mission is not a later invention. It arises from the text itself, which places John 14:28 in a farewell discourse about going away and coming again, not in a discussion of the divine essence. Reading the verse as a proof that Jesus is not God forces it to answer a question it was not asked to answer.
What Scripture Says About Jesus' Divine Identity
John 10:30 says, “I and the Father are one.” The context is Jesus' claim to give eternal life and to keep his sheep secure. The Jewish hearers understood the claim as a claim to deity, which is why they took up stones. If Jesus meant only that he and the Father were one in purpose, the reaction would be excessive; but if he meant one in essence, the response fits.
Philippians 2:5-11 is even more explicit. Paul calls believers to have the mind of Christ, who existed in God's form and did not consider equality with God something to be grasped, but emptied himself, taking the form of a servant. The passage ends with every knee bowing to Jesus and every tongue confessing him as Lord, language Isaiah reserves for God alone.
Colossians 1:15-20 calls Jesus the image of the invisible God and the firstborn of all creation. Firstborn here does not mean first created; in the ancient world it meant preeminence and heirship. The same passage says all things were created through him and for him, and that in him all the fullness of deity dwells bodily. A creature cannot create all things.
Why John 17:3 and 1 Corinthians 15:28 Do Not Help the Christadelphian Case
John 17:3 says, “This is eternal life, that they should know you, the only true God, and him whom you sent, Jesus Christ.” Christadelphians read only true God as excluding Jesus from deity. But the verse names both the Father and Jesus as objects of saving knowledge. To know Jesus is eternal life, which would be impossible if he were a mere creature. The verse distinguishes the persons while uniting them in the work of salvation.
First Corinthians 15:24-28 describes the end, when Christ delivers the kingdom to God the Father and is himself subjected to the one who subjected all things to him. This is the completion of the mission, not the demotion of the Son. The Son's reign as mediator ends not because he is inferior but because his work of redemption is finished. The passage ends with God being all in all, not with the Son ceasing to be divine.
In both texts, the Christadelphian reading assumes that any distinction of role implies a difference of nature. But the Bible presents Father, Son, and Spirit as distinct persons who are one God. Subordination in role does not cancel equality of being.
The Trinity in the Whole Counsel of Scripture
The word Trinity is not in the Bible, but the doctrine is the church's summary of biblical teaching. There is one God, and yet the Father is God, the Son is God, and the Holy Spirit is God. These are not three gods but one God in three persons. This is why Jesus can say he and the Father are one and also say the Father is greater than I, without contradiction.
Christadelphians often argue that the Trinity came from later councils rather than Scripture. But the councils did not invent the doctrine; they defended what the church already believed from the apostles against distortions. The earliest Christians worshipped Jesus, baptized in his name alongside the Father, and called him Lord in ways that would have been blasphemous if he were a creature.
None of this means Christadelphians are not sincere or morally serious. Many are devout and knowledgeable about the Bible. But sincerity does not settle truth. The question is whether their reading of John 14:28 and related texts does justice to the full witness of Scripture. It does not.
How to Talk with a Christadelphian Friend
Begin with respect and genuine listening. Christadelphians often know the Bible well and have thought carefully about their beliefs. Ask questions rather than making speeches. Ask what they think John 1:1 means when it says the Word was God, and how they understand Thomas's confession, My Lord and my God, in John 20:28. Ask how a creature can be the exact image of the invisible God and the one through whom all things were made.
Be ready to explain the difference between nature and role. Many Christadelphians have never considered that John 14:28 can be read as mission language without denying Jesus' deity. Show them how Philippians 2 and Colossians 1 place Jesus on the Creator side of the Creator-creature divide. Point out that the New Testament applies Old Testament Yahweh texts to Jesus.
Above all, pray and speak the truth in love. The goal is not to win an argument but to help someone see the glory of Christ as truly God and truly man, the only Savior. If they come to see that, they will not lose their love for Scripture; they will read it with new eyes.
Biblical fidelity check
John 14:28 establishes that Jesus, in his earthly mission, spoke of the Father as greater. It does not establish that Jesus is a creature or that the Father alone is God. The verse says nothing about the divine essence, the nature of the Son before the incarnation, or the relationship of the persons of the Trinity. To use it as a proof that Jesus is not God is to make it answer a question it never addresses, while ignoring passages such as John 1:1, John 10:30, and Colossians 1:15-20 that speak directly to Jesus' identity.
A common misreading is to treat greater as though it meant greater in nature. In ordinary speech, greater can refer to rank, age, authority, or position. When a vice president says the president is greater, no one concludes the vice president is a different species. Similarly, Jesus' words describe the Son's role as the sent one, not his essence. The misreading also forces a contradiction with the rest of the New Testament, where Jesus is worshipped, called Lord, and described as the Creator. Faithful Christians have always rejected that contradiction.

Frequently asked questions
Does John 14:28 mean Jesus is not God?
No. John 14:28 records Jesus saying the Father is greater, but the context is his departure to the Father, not a statement about his divine nature. Throughout the Gospel of John, Jesus speaks as the Son sent by the Father who lives in dependence on him. This is mission language. The same Gospel calls Jesus God and records Thomas confessing him as Lord and God. Subordination in mission does not deny equality of nature.
What do Christadelphians believe about Jesus?
Christadelphians believe Jesus is a created human being, sinless by God's grace and the virgin birth, but not God incarnate. They deny the Trinity and the pre-existence of Christ as God the Son. They teach that the Father alone is the one true God and that the Holy Spirit is God's power rather than a person. These beliefs are summarized in their statements of faith and distinguish them from historic Christianity.
Is Christadelphianism a cult?
That depends on how the word is used. If cult means a movement that denies essential Christian doctrines, then Christadelphianism fits, because it denies the deity of Christ and the Trinity. If cult means a controlling group, the label may mislead, since Christadelphians are often sincere and Bible-focused. The better question is whether their teaching agrees with Scripture. On the person of Christ, it does not.
