If Jesus Prayed for Unity, Why Is the Church So Divided?

On the night before he died, Jesus prayed that all who would believe in him might be one, as he and the Father are one, so that the world might believe the Father had sent him. It is one of the most specific prayers in Scripture, and by any outward measure it has not been answered. There are tens of thousands of Christian denominations. Churches split over music, over buildings, over personalities, over doctrines great and small. Protestants and Catholics and Orthodox have at times persecuted one another. Within a single town, believers who share a Bible may not share a meal. The objection is easy to state and hard to dismiss. If God the Son asked God the Father for one thing, and it did not happen, what does that say about the prayer, or about the God who heard it?

The strongest form of the question deserves to be put plainly. Either Jesus' prayer was not effective, in which case his relationship to the Father is not what the Gospel claims, or the church is not really the body of people he prayed for, in which case Christian identity is in doubt, or unity does not mean what it appears to mean, in which case the words have been emptied to save the argument. None of those is comfortable. A believer who has felt the sting of a church split, or who has watched Christians attack one another in public, has every right to press this.

Begin with what the prayer actually asks. Jesus prays that believers may be one as he and the Father are one, and then he describes that oneness. It is that they may be in us, in the Father and the Son. It is that the love the Father has for the Son may be in them. It is a unity of shared life and shared love, rooted in a shared indwelling. It is not, on its face, a prayer for a single institution, a single worship style, or agreement on every disputed point. That does not make institutional and doctrinal unity unimportant. But it means that the first thing Jesus asked for was that his people would be joined to God and to each other at the level of life and love, and that is a different question from whether they share a denomination.

Is that deeper unity real? Here the answer is more encouraging than the headlines suggest. Across every tradition that confesses Jesus as Lord, the same Scriptures are read, the same Lord's Prayer is prayed, the same creed is recited or at least believed, the same baptism is given, and the same Christ is worshiped. A Baptist from Georgia and a Lutheran from Minnesota and a Pentecostal from Nigeria and an Anglican from Sydney, put in a room together, will find that they agree about the things the New Testament treats as first importance: that Christ died for our sins, that he was buried, that he was raised, that he is Lord. Paul in Ephesians speaks of one body and one Spirit, one Lord, one faith, one baptism, one God and Father of all. He does not describe that as an aspiration. He describes it as a fact that believers are told to keep, to maintain, to make every effort to preserve. The unity is given. The task is to guard it.

This distinction between unity given and unity guarded is where much of the answer lies. Jesus' prayer was answered in the sense that the Spirit was poured out and a people was formed who are genuinely, spiritually one in him. It is being answered in the sense that Christians are commanded to live out that oneness, and often fail to. The failure is real and it is sin, and the New Testament names it as such. Paul rebuked the Corinthians for dividing along lines of favorite teachers. He and Barnabas parted ways sharply over a personnel decision. He opposed Peter to his face in Antioch over table fellowship. The early church was not a golden age of harmony from which we have fallen. It was a community of forgiven people learning, unevenly, to be what they already were.

A second consideration is the nature of prayer itself. When Jesus prayed in Gethsemane that the cup might pass from him, the cup did not pass. He also prayed that the Father's will would be done, and it was. Prayer, even the Son's prayer, is not a mechanism that overrides the freedom of those prayed for. Jesus prayed that Peter's faith would not fail, and it wavered badly, and then it held. The prayer for unity is of the same kind. It sets the direction of God's work in his people. It does not remove their capacity to resist that work for a season. Every schism is a place where believers have resisted what Jesus asked for. That is a judgment on the believers, not on the prayer.

A third consideration is that some division is the guarding of truth rather than the breaking of unity. The New Testament commands separation from those who deny that Christ has come in the flesh or who preach another gospel. A church that never divided over anything would be a church that had stopped caring what was true. The Reformation, whatever one thinks of its details, was at its root a dispute about how a sinner is made right with God, which is not a small matter. Divisions of that kind are painful, but the alternative, a unity that costs nothing because it means nothing, is not what Jesus prayed for either. He prayed for a people sanctified by the truth, in the same breath as he prayed for their oneness.

That said, honesty requires admitting that most church divisions are not of that kind. They are over pride, preference, power, and hurt feelings. Every believer who has been part of one knows that the theological reasons given were often not the real reasons. Here the objection lands with full force, and the right response is not defense but repentance. The scandal of a divided church is a scandal. It does hinder the world's belief, exactly as Jesus implied it would. Christians should feel that, and it should change how they speak about and to believers in other traditions.

Finally, Jesus' prayer has a horizon. He prayed that they may be brought to complete unity, and he prayed that they would be with him where he is and see his glory. The book of Revelation shows a multitude from every nation and tribe and language standing together before the throne. The prayer will be fully answered, in the same way that the prayer for the kingdom to come will be fully answered. The church now is a first installment, marred and partial, of what it will be. The gap between what Jesus asked and what we see is real, and it is temporary.

So the honest answer to the question is layered. Jesus prayed for a unity of shared life in God, and that unity exists among all who truly belong to him, visible whenever believers from different traditions recognize one another as family. He also prayed for that unity to be seen, and here his people have failed him often and badly, and the failure is sin, and the world has noticed. Some division has been necessary to protect the gospel. Most has not. And the full answer to the prayer lies ahead, when the one who prayed it returns. In the meantime, the prayer is also a command. Every Christian who reads John 17 is being asked to make it come true a little more, in the church they attend and toward the believers they find hardest to love. That is not a way of avoiding the objection. It is what taking it seriously looks like.
