ChristianAnswers.ai exists to make thoughtful, nuanced answers to difficult questions about Christianity easier to discover, using artificial intelligence to help foster a more informed, charitable, and curious community of Christ-followers and those exploring the way of Jesus.
Why I Made This
I grew up believing there was one Christian answer to just about every question that mattered. It took years to find out that wasn't true — not because Christianity is wrong, but because it was never one thing to begin with. Catholics, the Orthodox, Reformed Christians, Baptists, Pentecostals, Latter-day Saints, Jehovah's Witnesses — they don't just disagree at the edges.
On real, substantial questions, they build their answers on genuinely different foundations, and in most cases they've been doing it for centuries.
Finding that out later than I should have was disorienting in a way that took a long time to work through. I'm not the only one. A lot of people I know went through some version of the same thing: taught that the faith was simple and settled, then blindsided by how much real, substantiated disagreement was sitting underneath the version they'd been handed. For some people, that discovery is what starts them unraveling their faith entirely — not because the complexity itself is a problem, but because nobody told them it was there.
I don't want my kids, or anyone else's, to have to find that out the hard way. This site is my attempt to hand people the actual shape of the thing early and plainly, instead of letting them discover it later as a shock. Not because I think more disagreement is automatically better, but because the disagreement is real, whether or not anyone tells you about it up front.
I'm not trying to settle any of these questions here. I'm trying to nudge towards where the actual lines are drawn, who draws them, and why — and then point you to the real sources so you can go look for yourself. This isn't meant to be the last stop. It's meant to be closer to the first one.
Method
Every question on this site gets the same treatment: a small number of Christian traditions state where they land, and the page shows exactly how many hold each position and roughly what share of the world's Christians that represents. No tradition gets flagged as the outlier, and no tradition gets treated as the default. Which traditions show up is decided by two criteria, applied the same way every time.
Size
A tradition needs at least 5 million self-identified adherents worldwide, counted the same way for everyone from a single source — the World Christian Database, which tracks denominations specifically rather than broad religious identity. Worldwide, not U.S.-only: a site that only counted American Christians would already be telling a distorted story.
The 5 million line isn't arbitrary. It sits inside an actual gap in the data, between a cluster of traditions in the tens of millions and a cluster in the low single digits, so it isn't a number chosen to include or exclude anyone in particular.
There's no separate test for whether a tradition counts as sufficiently orthodox or historically legitimate. If tens of millions of people affirm something and can point to what they actually believe in writing, that's a real, substantiated position worth showing on its own terms — not something this site is in a position to adjudicate. Where a tradition sits well outside what most other Christians throughout history have held, that will be visible in the numbers themselves. Nobody needs to be told what to make of it.
A public, authoritative document
Every seated tradition has to point to something written — a confession, a catechism, an official statement of belief — that's actually available for anyone to go read, not something reconstructed from one figure's sermons or one person's idiosyncratic take on what the tradition believes. Where a tradition is genuinely too internally diverse to be represented by a single document — Baptists, for instance, don't have one confession that binds the whole movement, by design — the site represents the specific, documented body within it rather than forcing a single voice onto something that was never one voice to begin with.
Every source on every post links directly to the primary document itself. Not a summary of it, not this site's read on it — the actual thing, so you can check it yourself and keep going from there.
One more thing worth saying plainly: I know almost no one lives out their tradition exactly the way its official documents describe it. Individual Catholics, Baptists, Lutherans, whatever the label, vary enormously in what they actually believe and practice, and plenty would word their own position differently than their tradition's confession does. That's real, and this site isn't claiming otherwise. It's exactly why the second criterion is a publicly available, authoritative document rather than a survey of individuals or my own read on what a tradition "really" believes — a tradition's official teaching is the one thing that's actually checkable and consistent across a group that large. It's a defensible baseline, not a claim that every member of that tradition would sign off on every word of it.

Justin Bailey is an entrepreneur, technologist, and longtime student of theology and philosophy with a degree in Religion. His work has spanned software, artificial intelligence, finance, and real estate, while his deepest interests remain the big questions of Christian faith—what is true, how we can know it, and how Christians can think carefully across traditions without losing sight of Christ. ChristianAnswers.ai grew from that pursuit: using modern technology to make the breadth and depth of Christian thought easier to explore.
