There is something deeply disturbing about the Caleb Flynn case, not only because of the crime for which he was convicted, but because of what happened afterward.
According to the case presented at trial, Flynn texted his mistress that he would soon be free. Two hours later, he called police and claimed that an intruder had entered his home and killed his wife. Prosecutors argued that he had murdered her himself and then staged the scene, and the jury ultimately accepted that account and convicted him.
Yet even at sentencing, Flynn continued to insist that he was innocent. He stood before the court and his wife’s family and appealed to God as the ultimate judge of what had happened.
Watching something like that raises a difficult question: how can someone continue denying something when the evidence against him appears overwhelming?
Obviously, we cannot look directly into another person’s soul, nor should we pretend that we can psychologically diagnose someone from a courtroom video. Courts can also make mistakes, and a person who is truly innocent has every right to maintain his innocence and appeal his conviction. Still, the case raises a much larger question about human nature: can someone lie for so long, and defend that lie so completely, that eventually the lie begins to feel true even to him?
I think the answer is yes, and Catholic theology gives us a helpful way of understanding how something like that can happen.
Looking sincere does not mean someone is telling the truth
We tend to think sincerity is something we can recognize. We imagine that an innocent person will sound innocent, while a guilty person will seem nervous, evasive, ashamed, or obviously dishonest. Human beings, however, are not very reliable lie detectors.
A guilty person can appear completely calm, while an innocent person can be terrified, confused, or suspicious-looking simply because of the pressure he is under. Some people are naturally persuasive and composed, while others struggle to express themselves clearly even when they are telling the truth. Emotion can tell us something about what a person is feeling, but it cannot by itself tell us whether what he is saying is true.
Someone can therefore say something false with what appears to be complete conviction. Sometimes that is simply deliberate lying, but other times denial, rationalization, compartmentalization, habitual deception, or self-deception may also be involved. These things can overlap. A person may understand the truth at one level while spending enormous energy avoiding it at another.
Lying and lying to yourself are not exactly the same thing
An ordinary lie is relatively easy to understand. You know something is true, but you deliberately communicate the opposite because you want another person to believe something false. The Catechism defines a lie as speaking a falsehood with the intention of deceiving another person and emphasizes that lying is an offense against truth itself (CCC 2482–2485).
Self-deception is more complicated. A person cannot normally decide that two plus two equals five and simply force himself to believe it. What he can do, however, is control which facts he focuses on and which ones he avoids. He can reinterpret memories, minimize certain details, blame other people, create excuses, and repeatedly return to whatever version of events allows him to live with himself.
Over time, he may not completely erase his knowledge of what happened, but he can build walls around it. The truth remains somewhere in the background while the preferred story becomes the one he consciously rehearses and defends.
This may explain why someone can repeat a false story with extraordinary confidence. He is not necessarily going through the entire chain of evidence every time he speaks. Instead, he is repeating the version of reality he has chosen to inhabit, and eventually that story can become connected to his reputation, relationships, freedom, identity, and even his basic understanding of who he is.
At that point, admitting the truth means much more than admitting that one statement was false. It may mean allowing an entire image of oneself to collapse.
Every lie makes the next lie easier
A serious lie rarely remains isolated. Someone may begin by lying to escape the consequences of something he has done, but then another lie becomes necessary to protect the first. When inconsistencies appear, explanations have to be invented. When another person contradicts the story, that person may have to be discredited. Evidence has to be reinterpreted, inconvenient facts ignored, and the story repeated often enough that it can eventually be told without hesitation.
What began as a calculated falsehood can gradually become an entire alternative account of reality. That does not make the account true, of course, but it does mean that the person can become very practiced at living inside it.
This is where Aristotle and St. Thomas Aquinas are helpful. Both understood that repeated actions form habits. When we repeatedly choose what is good, doing good becomes easier. When we repeatedly choose what is evil, evil can also become easier. St. Thomas explains that human actions can produce stable dispositions in us, inclining us toward similar actions in the future (Summa Theologiae, I-II, q. 51, a. 2; q. 52, a. 1).
The same principle applies to honesty. The first serious lie may be difficult and accompanied by fear or guilt, while the tenth or twentieth may come much more easily. Eventually deception may no longer feel like an unusual departure from a person’s character because deception has slowly become part of that character.
In that sense, the person is no longer forming the lie. He is allowing the lie to form him.
Sin makes it harder to see clearly
Catholicism does not teach that sin is merely the violation of an external rule. Sin also damages the person who commits it.
St. Thomas speaks of four wounds associated with fallen human nature:
Ignorance in reason
Malice in the will
Weakness in the irascible (or irritable) appetite
and disordered desire in the concupiscible (in this case lustful) appetite (Summa Theologiae, I-II, q. 85, a. 3).
This does not mean that a sinner suddenly loses his intelligence. Someone can remain extremely clever, articulate, and capable while becoming increasingly blind when it comes to his own moral condition.
In fact, intelligence can sometimes make self-deception easier because an intelligent person can become very skilled at defending himself. Instead of asking what is actually true, he begins looking for the explanation that protects his reputation, minimizes his responsibility, shifts blame to someone else, or allows him to continue thinking of himself as a fundamentally good person.
Reason is still functioning, but it is no longer governing the passions and desires as it should. Instead, reason begins working for them. The intellect becomes an advocate for what the person already wants to believe.
That is one of the more frightening effects of persistent sin. A person may not become less intelligent at all. He may simply become increasingly talented at explaining why he is not really guilty.
Conscience can become numb
We sometimes speak about conscience as though it were simply a feeling somewhere inside us, but Catholic teaching understands conscience as a judgment of reason about the moral quality of a particular action. The Catechism calls it a “judgment of reason” by which a person recognizes the moral quality of a concrete act (CCC 1778).
Because conscience involves judgment, it has to be properly formed. It can be correct, but it can also be mistaken, neglected, manipulated, or repeatedly ignored.
Scripture even warns about the possibility of a conscience becoming “seared” through hypocrisy and falsehood (1 Timothy 4:1–2). Usually this kind of hardening does not happen all at once. The first serious lie may bring a great deal of fear, shame, anxiety, and interior conflict because the person still feels the contradiction between what he knows and what he is saying. If he continues repeating the lie, however, that resistance can gradually weaken. What once disturbed him deeply may eventually provoke very little reaction at all.
That does not mean the lie has become less serious. It means the person has become less sensitive to it.
The Catechism warns that repeated sin gives rise to vice, clouds the conscience, and corrupts our concrete judgment of good and evil (CCC 1865). This is why the absence of guilt is not necessarily proof of innocence. Sometimes a person feels at peace because his conscience is rightly ordered, but sometimes he feels little because he has spent years training himself not to listen.
Pride makes confession incredibly difficult
At the center of long-term denial we often find pride, because real confession requires more than acknowledging that something unfortunate happened. It means acknowledging personal responsibility: I chose this, I did this, and I was wrong.
That can be extraordinarily painful because confession destroys the excuses a person has constructed and exposes the difference between the person he wanted others to believe he was and the person his actions reveal him to have become.
This can become even more difficult when someone possesses a public Christian identity. A person may be known as religious, speak frequently about God, hold a position of trust, or enjoy a reputation for faithfulness. Admitting serious wrongdoing would then expose not only the sin itself, but also the enormous gap between the outward religious identity and the hidden life.
Religious language can therefore be used in two very different ways. A sinner can invoke God in genuine humility and ask for mercy, but someone can also invoke God in an attempt to strengthen a false narrative. If a person knowingly calls upon God as a witness to something he knows is false, the act becomes particularly serious because deception is now joined to the misuse of God’s name. The Catechism describes a false oath as calling upon God to confirm a lie and teaches that perjury shows grave disrespect toward the Lord (CCC 2150–2152).
Again, we cannot know exactly what was taking place inside Flynn’s conscience. The broader point is simply that religious language is not proof of truthfulness. Christ Himself warns that merely saying, “Lord, Lord,” does not prove genuine obedience to God (Matthew 7:21–23). Faith can transform the sinner, but religious appearance can also become another means of hiding from the truth.
The danger of becoming hardened
Catholic moral theology sometimes uses the word obstinacy to describe deliberate persistence in wrongdoing, and when that persistence is joined to a refusal to repent, it becomes impenitence.
This does not mean that everyone who maintains his innocence after conviction is obstinate. Wrongful convictions happen, and an innocent person should never confess to a crime he did not commit. Obstinacy becomes relevant only if a person really is guilty, knows what he has done, and deliberately settles himself against repentance.
If those conditions are present, the spiritual danger is enormous. The reason is not that God’s mercy somehow becomes exhausted. Christian teaching says precisely the opposite: no sin is greater than God’s mercy. The problem is that mercy does not destroy human freedom, and a person can refuse to admit that he needs forgiveness.
The Catechism teaches that God’s mercy has no limits, but that someone who deliberately refuses to accept his mercy through repentance rejects the forgiveness offered by the Holy Spirit. Such hardness can lead to final impenitence (CCC 1864).
If I insist that I have done nothing wrong, then I place myself in the strange position of refusing the very mercy that could restore me. It is not that God refuses to forgive the repentant sinner. Rather, the sinner refuses to approach God as someone in need of forgiveness.
Christianity therefore does not teach that murderers, criminals, or people guilty of terrible sins are beyond redemption. It teaches something far more hopeful: forgiveness remains possible even after grave evil, but forgiveness begins with truth and repentance.
Why confess when lying seems safer?
From a purely worldly perspective, continuing to deny everything can seem perfectly rational. Confession might damage an appeal, strengthen a legal case against you, destroy relationships, ruin your reputation, and expose you to humiliation or hatred. If those are the only things that matter, denial can seem like the safer option.
But the lie has a cost of its own. Someone who refuses to live in the truth must continually maintain the version of reality he has created. He has to remember what he told different people, suppress inconvenient memories, reinterpret evidence, and often begin treating people who know the truth as threats or enemies. What was originally supposed to protect him can gradually become its own kind of prison.
Christ makes a direct connection between truth and freedom when He tells His disciples, “You shall know the truth, and the truth shall make you free” (John 8:31–32).
That freedom should not be reduced to freedom from earthly consequences. A person can confess the truth and still go to prison. Repentance does not mean that justice disappears, nor does forgiveness require the victim’s family to pretend that nothing terrible happened. The Church recognizes the legitimate authority of the state to impose proportionate punishment in order to defend justice and the common good (CCC 2266).
What confession can restore is a person’s relationship with reality. A criminal who tells the truth, accepts responsibility, and genuinely repents may still spend the rest of his life behind bars, but he can begin to become inwardly free. Someone who spends his life defending a falsehood may avoid that confession while becoming increasingly bound to the lie necessary to maintain it.
Mercy does not oppose justice
Cases like this naturally provoke anger, and that anger should not simply be dismissed. A murdered woman is not an abstract example in a theological discussion. There is a victim, a family, and people who have to live with the consequences of what happened for the rest of their lives.
Christian mercy never requires us to pretend that evil is less evil than it really is. In fact, mercy depends upon truth. Forgiveness only has meaning when there is something that genuinely needs to be forgiven, reconciliation requires repentance, and healing requires that the wound first be acknowledged.
Wanting someone to repent therefore does not mean ignoring justice. It means taking moral responsibility seriously. Through the prophet Ezekiel, God declares that if the wicked man turns away from his sins and does what is right, “he shall surely live, and shall not die” (Ezekiel 18:21–23). God’s desire is for the sinner’s conversion, but conversion means turning away from evil rather than merely learning how to speak religiously while continuing to deny it.
This is also why Christians can pray for someone guilty of terrible crimes without betraying the victim. We can pray for the victim and her family, for justice to be done, and at the same time pray that the offender comes to repentance. Wanting a sinner to be converted is not the same thing as excusing his sin. It is asking that evil not be allowed to claim one more victory.
The uncomfortable part is that this applies to us too
It would be easy to read about a case like this and distance ourselves from it by saying that we are not murderers or criminals. The problem is that the spiritual process we are talking about does not usually begin with spectacular evil. It begins with much smaller acts of dishonesty and self-protection.
We exaggerate stories because we want to look better. We retell arguments in ways that make ourselves completely innocent. We conveniently leave out the part where we were wrong. We blame circumstances for choices that we freely made, or confess only those parts of our sins that allow us to remain sympathetic in our own eyes. We can even give our faults respectable names, calling resentment discernment, cowardice prudence, or vanity self-respect.
Little by little, we can become attached to our own explanations.
Nobody develops a hardened heart in a single moment. There are usually many smaller choices first, which is why the Catholic tradition places such importance on examination of conscience, confession, humility, and spiritual direction. These practices are not meant to trap us in constant guilt or obsessive self-analysis. They are meant to keep us connected to reality and to force us to confront smaller falsehoods before they have time to grow.
The important question, then, is not whether we have committed a crime comparable to the one in this case. The more useful question is much closer to home: What truth am I resisting because accepting it would require me to repent?
That is where the hardening of the heart can begin, but it is also exactly where grace invites us to stop.
Mercy still gets the final word
We do not know the final condition of another person’s soul, and as long as someone is alive, conversion remains possible. There is no sin more powerful than the grace of Christ, but grace does not work by confirming every story we tell ourselves. Grace brings us into the light.
The Catechism teaches that there is no offense, however serious, that the Church cannot forgive when there is sincere repentance, because there is no one so wicked that he should lose hope of forgiveness (CCC 982). The Cross itself reveals both the seriousness of sin and the greater abundance of divine mercy.
But mercy has to be received in truth.
A person may succeed in deceiving his friends, his family, the police, a jury, a church community, or even, to some degree, his own conscious mind. He cannot deceive God.
For the person determined never to repent, that should be terrifying. For the person who finally becomes willing to stop defending himself and tell the truth, however, it is also the beginning of hope, because the God who already knows the truth is the same God who is waiting to forgive.
