Why are there so many denominations?
Christians agree on the core. The differences are about secondary things — and they matter less than the gospel they share.
One Lord, one faith, one baptism.
Ephesians 4:5 · Berean Standard Bible
That all of them may be one, Father, just as You are in Me and I am in You.
John 17:21 · Berean Standard Bible
From a pastor
Yes, there are a lot of denominations — and most of them agree on the things that matter most: one God, three persons; Jesus fully God and fully man; saved by grace through faith; the Bible as God's word. That common centre is called the Nicene Creed, and it's recited every Sunday in most of the world.
The differences are real but secondary: how baptism is practised, how churches are governed, which gifts of the Spirit are still active, how end-times prophecy lines up. These matter, and Christians shouldn't pretend they don't. But they are family disagreements inside a family that worships the same Lord.
Scholar's note
The major streams (Roman Catholic, Eastern Orthodox, Protestant) split in 1054 and 1517 over real theological disagreements (papal authority, justification by faith) — not over Jesus. Within Protestantism the further divisions usually trace to questions of church governance and sacramental theology, not the core gospel.
Historian Mark Noll (The Civil War as a Theological Crisis, Turning Points) shows that even the deepest divisions have produced traditions that recognise one another as genuinely Christian wherever the Apostles' and Nicene Creeds are confessed. Mere Christianity, Lewis's term, is the shared room — the denominations are different rooms in the same house.

When you visit a church, what would tell you it's preaching the same Jesus the apostles did?
