Devil’s Advocate: Can Your Beliefs Survive This Opponent?

Most of us go through life under the impression that our beliefs, values, and worldviews are completely unshakeable. We carry our convictions proudly, viewing ourselves as people of deep intellectual clarity and moral certainty. We assume that because we hold a belief tightly, it must be true.

But the reality is far more uncomfortable: Until your deepest assumptions are aggressively dragged into the ring and forced to fight an actual opponent, your worldview is nothing more than a soft hypothesis. It is an untested theory, and just as I have previously discussed, an untested life inevitably breeds a quiet, nagging doubt.

In my previous article, “The Character Audit: If You Were Tested, Would You Pass?” I talked about the profound spiritual cost of a soft, unchallenged life. I looked at Seneca’s counterintuitive warning to his friend Lucilius: “I judge you unfortunate because you have never lived through misfortune. You have passed through life without an opponent.” And I pointed out how that adversity acts as the auditor of the soul, checking the books to see if our internal strength is real or if we are just incredibly lucky.

But the character audit does not stop at our habits and emotional resilience. It extends directly into our minds and the core of our spiritual defense. Just as a sheltered life deprives your character of the friction it needs to grow, a sheltered mind deprives your beliefs of the rigorous testing required to turn them into steel.

And to solve the hidden unease of holding unchallenged ideas, we must look to a fascinating historical practice designed specifically to destroy soft assumptions: the role of the Devil’s Advocate.

The Vatican: The Origin of the Counter-Argument

In modern speech, playing “devil’s advocate” is often dismissed as a minor social nuisance. We use the phrase to describe someone who derails a conversation at a dinner party or mindlessly argues a contrarian point just to be difficult. But historically, the role was an incredibly serious, institutional audit.

The practice originated within the Roman Catholic Church in the late 16th century during the canonization process for sainthood. When a candidate was nominated to be a saint, the Vatican did not just gather their supporters to sing their praises. Instead, they formally appointed an official called the Promotor Fidei, popularly known as the Devil’s Advocate.

This person’s entire job description was to serve as a ruthless, aggressive opponent to the candidate’s legacy. They were tasked with digging up every hidden flaw, questioning every reported miracle, uncovering any past moral compromise, and finding every possible reason why the candidate was NOT worthy of sainthood.

This process was not invented to destroy good people or tarnish holy reputations. It was an institutional recognition that true sanctity must be completely watertight. If a candidate’s life and character could survive the absolute worst accusations thrown at them by a professional auditor, only then could the Church declare their legacy unshakeable.

This historical reality reminds me again so much of what I wrote about the financial world in The Character Audit: “An audit is a systematic examination of records to ensure everything is as it seems. In the spiritual world, adversity is the auditor; it comes to check the books of our soul; it does not just come to destroy us; it comes to reveal us.”

The Devil’s Advocate was the Vatican’s institutional auditor of holiness. It was the realization that you can not truly crown something as pure until it has successfully survived the fire.

Yes, the Devil’s Advocate attacks the individual, but before I continue, let me make it very, very clear that for this article, the idea of the Devil’s Advocate is not only attacking the individual; it is also attacking your belief and to find out if you possess the knowledge, capacity, and willingness to defend it. Because one can hold a belief and live by it but not be able to defend it, while another can hold a belief, not live by it for some reason, but be able to defend it. And I really hope you get my point.  

John Stuart Mill and the Danger of the Soft Mind

Centuries after the Vatican institutionalized this process, the British philosopher John Stuart Mill took this exact concept and applied it to the human intellect. In his brilliant 1859 text, On Liberty, Mill argued that playing devil’s advocate to your own mind is the single most vital requirement for human intelligence.

Mill looked at how the average person holds their beliefs and noticed a terrifying pattern. Most people build an air-conditioned bubble around their thoughts. They surround themselves with books, commentators, and friends who echo their existing opinions. They protect their worldviews from critics, praying for ideological peace and avoiding any path that might cause intellectual friction.

But Mill warned that this constant peace is a dangerous mask, and so he famously asserted that if you know only your side of the argument, you do not even know that. What he means is that you do not then know enough to be able to defend it if you only know your side of the argument.

Dead Dogma vs. Living Truth

When you protect a belief from being questioned, you do not make it stronger; you make it incredibly fragile. Mill asserted that an unchallenged belief eventually rots into a dead dogma.

A dead dogma is a rigid, empty phrase that you repeat entirely on autopilot. You follow the rule, but you no longer understand the deep “why” behind it. And so it becomes a superficial habit, an empty shell of an idea that completely shatters the moment life presents you with a real-world crisis.

And on the other hand, a living truth is a conviction that has been dragged into the dirt, punched in the face by counter-arguments, and still managed to keep its feet.

Challenging your assumptions keeps them alive, robust, and functional. And so, John Mill’s ultimate takeaway is profound: The goal of a devil’s advocate is not to mindlessly destroy your convictions but to test them. If your belief can survive a rigorous, hostile questioning process and still stand, only then do you have the right to call it a living truth.

The Mirror’s Accusation: Betraying Your Own Mind

When we refuse to play devil’s advocate to our own thinking, we commit a profound act of intellectual dishonesty. We settle for the comfortable “impression” of knowledge rather than the hard reality of truth.

And this brings me back to that heavy sentence that I wrote about in my previous article, the sentence that strips away our excuses and leaves us standing exposed before our own conscience: “Your worst sin is that you have destroyed and betrayed yourself for nothing.”

We most times look at betrayal as an external act, something done to us by a political leader who misleads us, a friend who sells us out, or an environment that treats us unfairly. But the most lethal betrayal happens in the privacy of your own mind when you choose to live a soft, unexamined life.

When you allow lazy habits of thought to persist, when you let your intellectual discipline slip, and when you refuse to look at the flaws in your own logic, you are actively dismantling your own potential.

You are betraying yourself for nothing when you choose the comfort of an easy, unverified opinion over the hard work of building an unshakeable mind. And the mirror does not; if you are terrified of an opponent questioning your beliefs, it is a sign that you secretly know your intellectual muscle does not carry any weight. And mind you, it is not necessarily about winning every argument, but the shying away and the fear of being challenged in something you claim to believe; then and again, it is a sign that you secretly know your intellectual muscle does not carry any weight.

Even now, I remember the exact moment I first encountered and read those words a few months ago. It was not in a grand church or building, or at a motivational seminar; it was a quiet collision between my eyes and a sentence that seemed to vibrate with a haunting, ancient authority, or at least that was how it felt, and still does. Since that day, it has been weighing on my heart like a stone that refuses to be moved. I have carried it into my mornings and let it settle over my restless nights; it is a sentence that strips away every excuse I have ever made and leaves me standing naked before my own conscience. It whispers to me in the silence of my reflections, reminding me of the ultimate tragedy: “Your worst sin is that you have destroyed and betrayed yourself for nothing.”

We spend so much of our lives guarding against external enemies; we pray for protection from those who might harm us; we build walls against critics; and we navigate the bad paths of the world, hoping to remain untainted. But follow me for a moment, my dearest readers, what happens when the enemy is not at the gate? What happens when the person dismantling your destiny is the one staring back at you in the mirror? We often think of betrayal as something done to us by a friend or a stranger, but the most lethal betrayal is the one we commit in the privacy of our own choices. When I look at the habits I have allowed to persist and the discipline I have let slip, the mirror does not lie, and so again I am reminded of the statement “Your worst sin is that you have destroyed and betrayed yourself for nothing.”

The Ultimate Win: “He Has Nothing on Me”

When the ultimate opponent arrives to audit your life, what will he find? This brings me to the deepest, most profound dimension of the character audit, the spiritual test of absolute Immunity, untouchability, and sacredness. In the Gospel of John 14:30, we find a statement delivered by Christ that represents the gold standard of an airtight soul.

As the hour of His supreme test approached, He looked at His followers and uttered words that have echoed across different translations through ancient times, each revealing a unique view of an uncompromised life.

The Claim and the Power

I want us to take a moment to consider how different translations render this monumental confrontation with the ultimate adversary:

New International Version: “…, for the prince of this world is coming. He has no hold over me.”

New Living Translation: “…, because the ruler of this world approaches. He has no power over me.”

English Standard Version: “…, for the ruler of this world is coming. He has no claim on me.”

Berean Standard Bible: “…, for the prince of this world is coming, and he has no claim on Me.”

When the NIV says the opponent has “no hold over me,” and the NLT says he has “no power over me,” it speaks directly to our internal sovereignty. An opponent can only hold onto you if you have given him a handle. If you harbor secret cowardice, unconfessed compromise, or hidden greed, you have handed the adversary a lever to control you.

The ESV and BSB use the word “claim.” In a legal or financial audit, a claim means there is an unpaid debt, a piece of property that belongs to someone else, or a discrepancy in the books. To say the ruler of this world has no claim on you means your accounts are entirely clean. There is no hidden transaction, no sold-out virtue, and no compromised ground.

The Emptiness of the Threat

Let us look even closer at the older, more literal translations of this same verse:

Berean Literal Bible: “…; for the ruler of the world comes, and in Me he has nothing.”

King James Bible: “…: for the prince of this world cometh, and hath nothing in me.”

New King James Version: “…, for the ruler of this world is coming, and he has nothing in Me.”

Think about the absolute spiritual authority of those four words: “has nothing in me.” When the auditor of this world arrives to inspect the deep, dark corners of your heart, does he find a matching frequency? Does he find a secret love for comfort that he can use to make you compromise? Does he find a hidden price tag where you are willing to sell out your values for safety?

To pass the ultimate audit means that when the opponent searches your soul, he finds absolutely zero leverage. He finds nothing that belongs to him, and he finds an empty ledger because your character has been purified in the fire, leaving no room for betrayal.

The Daily Stoic Podcasthas come be one of my favorite podcast to listen to and just recently I listened to on of the episode that has got me thinking ever since I did, and you have already seen from the title, the topic is “Don’t Sell Out” 

The episode started with a question Epictetus asked in one of his discourses:  “Your respect, trustworthiness and steadiness, peace of mind, freedom from pain and fear, in a word, your freedom. For what would you sell these things?”

Like I have come to love asking my readers, take a moment to think about it, you, yes you! Take a moment, take it personal because I’m asking you, so again to you my friend:  “Your respect, trustworthiness and steadiness, peace of mind, freedom from pain and fear, in a word, your freedom. For what would you sell these things?”

And just as Ryan Holiday went further to state that; the answer, too often, is “for pennies on the dollar.” We trade our word for a small edge in business. We mortgage our self-respect for fancy friends or fleeting fame. We auction our freedom for jobs that drain our souls or relationships that chip away at our dignity.

And this is true for many of us, we trade respect, trustworthiness, peace of mind, freedom from fear, our freedom, our words for pennies or at best even for millions, we sell our soul or relationship for fancy friends, we come to the point where our words no longer carry water, holds no meaning even to ourselves, sell ourselves and  core values for materials things, chipping away at our dignity, in pursuit for fame and recognition, at the core we do all of these at the expense of my soul, and become properties to people and materials, again at the expense of our identity, values and principle.

Finding Your Opponent: How to Audit Your Assumptions

How do we solve the underlying insecurity of the untested mind without waiting for a tragedy or an unexpected spiritual crisis to ruin our lives? Just as we must voluntarily seek out physical and emotional struggles to test our character, we must actively recruit opponents for our ideas and our conduct.

You must step out of your air-conditioned comfort bubble and deliberately audit your life using these three practical steps:

Build the Strongest Counter-Case

Pick your most deeply held belief or strategy. Instead of reading things that constantly agree with you, force yourself to spend time researching the absolute best, most intelligent arguments against your position. And do not look for weak arguments just to easily defeat them; find the most brilliant contrarian minds on the topic and let them challenge you. If your ideas can not survive a professional devil’s advocate, they are dead dogmas, not living truths.

Invite the Critics In

Stop building walls against critics by running away from them, but rather build walls by having the right, honest, correct, and truth reponds to their criticism. When someone challenges your logic, questions your integrity, or points out a flaw in your habits, do not immediately react with anger, pride, or emotional defensiveness. View them as a free auditor for your soul! Let them check your books! Look at the raw data of your reaction. Did you crumble into bitterness, or did you use the critique to refine your thinking and come back stronger, and most importantly, come back with the truth?

Clear the Hooks

Consistently perform an internal clearance. Ask yourself the hard questions: Where am I vulnerable? What secret attachments do I have that an opponent could use to control me? If you are obsessed with comfort, reputation, or applause, the ruler of this world has a massive claim on you. You must systematically untangle yourself from these dependencies so that when the test arrives, you can confidently state that the adversary has no hold over your choices.

Conclusion

And so, my dearest readers, the ultimate question, just like from the Character Audit, remains unchanged, moving effortlessly from your actions into your thoughts and your spiritual core: If you were tested today, would you pass?

Do not be content with a mere impression of intelligence or a surface-level appearance of integrity. Do not spend your life floating in comfort with an unexamined routine, cheap validation, and pre-programmed opinions. The audit is a necessary part of a life well-lived; it is the only process that moves your soul from soft theory to unyielding reality.

If your beliefs and choices are currently in the fire of criticism, struggle, and doubt, do not run away. Stay there until the gold is completely purified! Appreciate the clarity that comes from the friction. And if your mind is currently resting in the easy shade of unchallenged compliance, step out into the heat! Rise to the challenge! Bring on the devil’s advocate, allow your assumptions to be tested, clear out every hidden compromise, and ensure that you know exactly who you are, not just in smooth words, but very, very importantly in unshakeable character, verified truth, and victorious conduct!
