When "Christian" Means Nothing
The Problem With Pure Self-Identification
magine a guy born and raised in Tokyo. He has Japanese parents, holds a Japanese passport, speaks zero Gaelic, and has never set foot anywhere near the UK. One day, he turns to you and says, "I’m a Scotsman."
If you point out that he lacks literally every defining characteristic of being Scottish, and he fires back with, "You're committing a No True Scotsman fallacy!" - you'd probably laugh. It’s an absurd argument.
Yet this exact breakdown in logic happens all the time in debates over religion, ethics, and identity.
I recently got into an argument online with someone who claimed that if a person calls themselves a Christian, you have to accept it at face value - no matter what they actually believe, what they know, or how they act. When I tried to set even the barest minimum standard, my opponent accused me of falling fowl of the "No True Scotsman" trap.
It got me thinking: when did basic categorization become a logical fallacy?
The "Fallacy Fallacy"
The actual "No True Scotsman" fallacy happens when someone moves the goalposts on an extra rule just to protect a stereotype.
For instance, if I say "No Scotsman puts sugar in his porridge," and you point to a guy from Glasgow who does, I’m being fallacious if I reply, "Well, no true Scotsman does!" Sugar habits have nothing to do with the actual definition of being Scottish. I just made up an extra rule on the fly.
But pointing out that a guy in Tokyo with no ties to Scotland isn't Scottish isn't a fallacy. It’s just how language works.
If a word doesn't require any objective criteria beyond someone claiming the label, the word stops meaning anything. Insisting that a category has baseline boundaries isn't gatekeeping; it's just basic logic.
Beliefs Aren't Invisible
My debate partner’s next move was a classic retreat: "Well, beliefs are internal, so we just have to take their word for it."
Sure, nobody can read minds. But in philosophy and cognitive science, a belief isn't an invisible ghost - it's a disposition to act. What you actually believe shows up in how you live.
If I tell you I'm convinced my house is currently on fire, but I stay sitting on the couch scrolling on my phone, you don't say, "Well, I guess I have to take his word for it." My behavior proves I don't actually believe the house is on fire.
Even Christian scripture makes this exact point. Jesus didn't say "take everyone's word for it"; he said "By their fruit you will recognize them." Saying you accept someone as "Lord" (a word that literally means ruler or master) while completely ignoring their teachings means one of two things: you don't actually know what the word means, or you're just wearing the label for social credit.
How the Label Got Hollowed Out
So how did we end up with millions of people using a 2,000-year-old religious label while tossing out its core tenets?
Back in 2005, sociologists Christian Smith and Melinda Lundquist Denton studied American religious views and coined a term for what they found: Moralistic Therapeutic Deism (MTD).
Instead of traditional Christian concepts like repentance, self-sacrifice, and living out the teachings of Christ, MTD boils down to five basic vibes:
- God created the world and keeps an eye on things.
- God wants people to be nice and fair (based on whatever society currently considers "nice").
- The main goal of life is to be happy and feel good about yourself.
- God doesn't need to be involved unless you run into a problem.
- Good people go to heaven when they die.
Under MTD, morality isn't rooted in scripture or historic creeds - it's rooted in whatever feels right to you. If a religious rule makes you feel guilty or uncomfortable, you ditch it. God gets demoted from a sovereign ruler to a cosmic therapist whose only job is to validate your personal happiness.
Getting Our Terms Straight
If you want to hold your ground in these debates without getting bogged down in semantic arguments, it helps to drop loaded phrases like "real Christians" or "true Christians." Those words sound like you're passing a personal purity test, which gives your opponent an easy opening to scream "No True Scotsman!"
Instead, use the language sociologists use:
- Cultural Nominals: People who use the label purely as an ethnic, regional, or political identity tag - a tribal flag - without practicing the faith or holding its core convictions.
- Practicing Adherents: People who actually align their lives with the baseline criteria of the religion - holding its core beliefs and making a real effort to live out its ethics.
At the end of the day, words have to mean something. Pointing out the massive gulf between a "cultural nominal" and a "practicing adherent" isn't a logical flaw - it's just calling things what they actually are.
