It is one of the most common objections I hear, and one of the most reasonable-sounding: “If Christianity is true, why are there forty thousand denominations? You can’t even agree among yourselves.” The number gets thrown around to suggest hopeless chaos — as if every Christian believes something different and the whole thing is a free-for-all. I want to take the objection seriously, because it deserves an honest answer, and then I want to show you why the situation is far less damning — and far more understandable — than it first appears.

Let me say two things at the outset that need to be held together. First, the divisions among Christians are real, and some of them grieve me; Jesus Himself prayed for the unity of His people, and we have often failed Him here. Second, the “forty thousand denominations” statistic is wildly misleading — it counts every independent congregation and national variation separately, so that a single network of identical churches in a hundred countries can be tallied as a hundred “denominations.” The real landscape is far more unified than the number suggests.

Essentials and secondary matters

The key that unlocks this whole question is a distinction Christians have summarized for centuries: in essentials, unity; in non-essentials, liberty; in all things, charity. The essentials — the core of the faith — are remarkably agreed upon across the vast majority of Christians: one God in three persons, the deity and humanity of Christ, His death and bodily resurrection, salvation by grace through faith, the authority of Scripture, the call to holiness, the hope of Christ’s return. On these, an evangelical Baptist, a Presbyterian, a Methodist, and a Pentecostal would nod in agreement. The denominations differ mostly on secondary matters: how a church should be governed, whether to baptize infants or believers, exactly how Christ is present in communion, what worship should look like, how the gifts of the Spirit operate today. These are not nothing — sincere people hold them sincerely — but they are not the gospel, and disagreement on them does not put anyone outside the faith.

So when you see different denominations, you are usually not seeing different religions. You are seeing the same family living in different houses, with different furniture and house rules, all gathered around the same Father and the same Lord.

Where denominations came from

How did we get here? Several honest reasons, not all of them bad. Some divisions came from genuine recovery of truth — the Reformation, for instance, was largely an effort to recover the gospel of grace that had been obscured. Some came from differences of conscience over how to read particular passages. Some came from geography and culture — churches in different lands developed different forms. And some, I must admit, came from sin — pride, personality clashes, power struggles, and stubbornness, the same carnal divisiveness Paul rebuked in the very first generation:

For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal? Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man? I have planted, Apollos watered; but God gave the increase. 1 Corinthians 3:4–6

Notice that division over leaders and parties is nothing new — it showed up before the ink on the New Testament was dry. Paul calls it carnal, fleshly, immature. So when modern denominationalism is driven by ego and rivalry, it is simply the old Corinthian problem in new clothes, and it deserves the same rebuke. But notice also Paul’s remedy: he points away from the human leaders to the God who gives the increase. The cure for division has always been to fix our eyes higher than our camps.

Jesus prayed for unity

We should feel the weight of this, because Jesus did. On the night before He died, He prayed specifically for the oneness of all who would believe in Him:

That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. John 17:21

This is sobering: our unity is meant to be evidence to the world — that the world may believe. When Christians fight pettily and split needlessly, we damage the very witness Jesus prayed we would carry. So I do not wave away the scandal of division; I feel it. But notice what kind of unity Jesus prays for — not necessarily a single worldwide organization, but a unity like His own with the Father: a unity of love, truth, and shared life. That kind of unity can exist across denominational lines, and often does, wherever Christians recognize one another as family in Christ.

The unity that already exists

Here is what skeptics usually miss: beneath the visible variety, there is a profound unity that already exists among true believers. Paul states it in a string of “ones”:

There is one body, and one Spirit, even as ye are called in one hope of your calling; One Lord, one faith, one baptism, Ephesians 4:4–5

One body, one Spirit, one hope, one Lord, one faith. That is the bedrock. I have stood with believers from wildly different traditions — different labels on the door, different songs inside — and found us instantly family the moment we spoke of Christ. The denominations are like different regiments in one army, different instruments in one orchestra. The variety is not all loss; it allows the gospel to take root in every culture and temperament, and it lets believers find a congregation where they can genuinely worship and grow. A measure of diversity, held in love, can even be a strength.

What this means for you

So how should you think and act in the face of denominations? A few words of counsel. Don’t let the divisions keep you from Christ. The objection “there are too many denominations” is often a reason to stay at arm’s length from faith altogether — but the divisions are about secondary matters, and the question that actually decides your eternity is not “which denomination?” but “what will you do with Jesus?” Start there: What Is the Gospel? Major on the majors. Hold the essentials with conviction and the secondary matters with humility, and extend charity to believers who land differently than you on the non-essentials. Find a faithful local church and commit. Don’t shop endlessly for the perfect one; find a congregation that teaches the Word, lifts up Christ, and loves people, and throw yourself into it — I say more about why this matters in What Is the Church? and Do I Have to Go to Church? And love the wider family. Recognize and bless genuine believers in other traditions; we will spend eternity together, so we may as well start treating one another as family now.

The skeptic sees forty thousand denominations and concludes Christianity is chaos. The closer truth is this: a vast family, scattered across cultures and centuries, divided in many small ways and united in the one way that matters most — gathered, all of us, around a single Lord who died and rose, and who prayed that we would be one. The branches are many. The root is one. And the root is Christ.
