After years of comparing his own Christian beliefs with the other great world traditions, Dr. Craig Hazen reduced his conclusion to three words: “Christianity is weird.” He did his doctoral work in religious studies at the University of California, Santa Barbara, and he meant the word as a description. Most religions place their center in inner experience or practice. Christianity places its center in a public historical claim, the resurrection of Jesus, which could in principle be checked and found false. That makes it a different kind of thing.
Hazen pictures religion as a box. You can try to force Christianity into it, he says, but “it won’t go in the box because it really turns out not to be much of a religion after all.” To see why, the idea has to be built in order: what people usually mean by religion, what it means for a claim to be testable, and where Christianity stands once both are clear.
What do most people mean by “religion”?
Hazen observes that when most people hear about any religion, “they think religion is a particular kind of thing.” In the popular picture, that thing is private and inward. A person chooses it because it helps, and judges it by whether it brings peace, moral direction or a sense of connection. Nobody expects it to answer to evidence. Hazen notes that for many secular people the word belief already carries this meaning: “when they hear belief, they think blind faith.”
If every religion fits that description, the claim that all religions are basically the same follows almost automatically. They would differ the way styles of meditation differ, each valid for whoever finds it meaningful. Nobody could be wrong, because nobody would be claiming anything that could be wrong.
Hazen’s argument is that Christianity falls outside that box because of the kind of claim it makes.
What does it mean for a belief to be testable?
Hazen came to religious studies from science. One of his earlier degrees was in biology, and he worked in research. His habit from the lab was simple: a claim gets checked against the world. In his words, “you gotta test your theories.”
A claim is testable when evidence could count for it or against it. Suppose someone says a certain song moves them. No historian can refute that, because it reports an inner response and the speaker is the only authority on it. Now suppose someone says the song was recorded in a particular studio in a particular year. That claim can be wrong. Records, witnesses and physical traces bear on it. The first statement is about the speaker. The second is about the world.
Christianity involves more than a historical fact, of course. It involves trust in a person, prayer and changed lives. The comparison only clarifies what the faith finally stands on, and here Hazen’s comparative study landed on a sharp result. Christianity, he says, “is set apart in rapid, dramatic fashion from the other great world religious traditions, in that it can be tested.” Or more simply: “It’s a testable religion.” Its claims can be brought into something like a scientific setting, questioned hard, and examined to see whether they hold.
How do other traditions handle the question of testing?
The natural reply, which Hazen says he hears from secular people, is that surely all religions are testable. His answer is that they are not, and they step away from testing in different ways. Two of his examples show the range.
Some traditions decline testing from the start. Hazen’s example is Zen Buddhism, where outside verification is beside the point. As he describes it, “what’s important to a Zen Buddhist is what’s going on inside the Zen Buddhist.” Progress toward enlightenment through discipline and meditation is measured inwardly, so a demand for external evidence misreads what the practice is for.
Other traditions sound testable at first. Mormonism, one of the traditions Hazen studied in depth, makes concrete historical claims. Gold plates etched with ancient characters were translated by Joseph Smith, and the resulting Book of Mormon tells the story of ancient peoples in the Western Hemisphere. On paper, a historian could investigate all of it. Hazen reports that in conversations with missionaries at his door, local church leaders, faculty at Brigham Young University and even apostles of the church, the pattern repeated. When the hard historical questions came, the conversation turned to an inner confirmation, the traditional burning in the bosom. His summary: it “sounded like it was testable, but then it really wasn’t once you started to actually ask the hard testing questions.”
That is Hazen’s account of his own encounters, and Latter-day Saints would describe their faith differently. The logical point survives the disagreement. A claim that moves to a feeling whenever evidence is raised functions, in practice, as a feeling.
Lisa Fields drew out the consequence for Christians. If a believer’s confidence rests only on a feeling, that believer has nothing to say when a Mormon reports feeling something too. Two inner experiences can sit side by side, and neither can settle anything. Fields sees the same problem in what she calls a “buffet spirituality,” taking a little from several traditions and keeping whatever suits the person. Hazen agrees that such a faith is chosen because it works for the one choosing. The questions it leaves unasked are whether any of it is true and, as Hazen puts it, “is there any way I can know that it’s true or not?”
After years of comparison, his verdict was blunt: “every religion I’ve looked at really doesn’t have much going in terms of testability.” In Christianity, by contrast, testability sits right at the center.
Why does Paul stake everything on the resurrection?
The clearest support for Hazen’s claim comes from the Bible itself. He calls a section of 1 Corinthians 15 “one of the strangest passages in all of religious literature,” and says nothing like it appears in the Bhagavad Gita, the Buddhist Tripitaka, the Quran or the Book of Mormon.
The setting matters. Paul is writing to a church in Corinth where some members were saying there is no resurrection of the dead (1 Corinthians 15:12). He is correcting believers, and he does it by spelling out what follows if they are right. In 1 Corinthians 15:14 he writes:
And if Christ be not risen, then is our preaching vain, and your faith is also vain.
He repeats the point in 1 Corinthians 15:17: “And if Christ be not raised, your faith is vain; ye are yet in your sins.” The KJV word “vain” means empty or without effect, and other translations render it “futile” or “useless.” Then, in 1 Corinthians 15:19: “If in this life only we have hope in Christ, we are of all men most miserable.”
Hazen’s paraphrase of the logic is plain: if the event did not happen, “our faith is bunk, you ought to go do something else.” Paul offers no fallback to moral teaching or spiritual experience; everything hangs on one event. Earlier in the chapter, in 1 Corinthians 15:3-8, he lists people who saw the risen Jesus, including a group of more than five hundred, most of whom he says were still living. A writer who names living witnesses expects his claim to be checked.
The Christian faith holds that this resurrection was bodily and historical, something that happened in space and time. Paul’s argument shows the cost of that conviction. A faith built this way can be wrong, and its own Scriptures say so.
Isn’t every religion special in its own eyes?
This is the strongest objection. Every tradition thinks it has the truth, so the claim that Christianity is different could look like the Christian version of what everyone says.
Hazen’s argument does not depend on how Christianity feels to Christians. It depends on a structural feature anyone can examine. Where does a tradition place its central claim, inside the practitioner or out in public history? A Buddhist, a Muslim or an atheist can read 1 Corinthians 15 and confirm that Paul ties the faith to a historical event. That is an observation about a text, open to anyone who reads it.
Two limits keep the argument honest. Testable does not mean proven. Testability describes the kind of claim being made, and the verdict still has to be reached. Hazen goes further and argues that the historical record supports the conclusion that Jesus was alive, then dead, then alive again, and that a person can investigate it. That is his argument, and it stands or falls on evidence. Showing that Christianity is testable brings a person to the right question without answering it.
The second limit concerns believers themselves. Hazen is candid that many Christians hold their faith as a helpful choice. Describing that kind of faith, he says, “that’s probably what most Christians are doing.” The difference he identifies lies in what the faith rests on. Individual believers may hold it loosely, as a preference, but the faith itself leaves no room for preference to be the last word.
None of this requires contempt for other traditions. Hazen’s own practice in conversations with Buddhists and Muslims is to turn the discussion toward the person of Jesus and the question of whether he rose. The comparison becomes respectful precisely because it moves away from ranking experiences and toward a question both people can look at together.
What changes once you see the difference?
Hazen describes what happens when he tells someone from another faith, “I think Jesus actually came back from the dead.” People assume it is simply his belief. He explains that he is making a claim he thinks can be investigated: “rather than just saying, that’s what my religion teaches, I’m saying, and I can know it to be true.”
He says the resurrection “cuts through the spiritual fog like nothing else,” and the reason follows from everything above. Inner experiences cannot be weighed against each other. A claim about the past can be. “Christianity demands to be taken seriously as a real world explanation,” Hazen says, and that demand is what keeps it out of the box.
Asking whether all religions are basically the same assumes they are all the same kind of claim. Christianity breaks that assumption by resting on an event. So the question that matters most about it is the one Paul raised in Corinth: did it happen? That question has evidence attached, and a person can go and look.
