Summa Made Simple

We’re often taught that anger is something to suppress, control, or feel guilty about. But what if anger itself isn’t the problem? This episode takes a surprisingly different approach: anger can be good. The key is what happens after the emotion arrives. Anger is a desire for revenge—but revenge can mean lashing out blindly, or it can mean correcting what is wrong and restoring what has been damag...

The argument about LGBT often gets buried under politics, identity, biology, rights, social constructs, and competing definitions of freedom. But this episode strips all of that away and asks a much more basic question: what if God actually created human nature with a purpose? If you believe God made you, then your body—and the way it is ordered—can’t simply be raw material for you to redefine acc...

The strongest argument for homosexual sex is also one of the simplest: two consenting adults should be free to do what they want with each other. This episode asks whether that principle can actually bear the weight we put on it. We already accept limits on what consenting adults may do—to their bodies, to one another, and even in private relationships. So why? The argument leads beyond homosexual...

A thought appears. A feeling follows. Pleasure kicks in. Did you just sin? Not necessarily. And this is where the argument gets much more interesting. The distinction explored in this episode is between experiencing a pleasure and consenting to it . You don’t necessarily choose what enters your imagination, what catches your eye, or what your body reacts to. But you do have a choice about whether...

“I love God. I go to Church. I pray. I help people. Surely God will forgive me for living with my partner?” Aquinas takes that argument seriously—and gives it a much harder answer than we might expect. Good works matter, but not because they earn us a place in heaven. They prepare us to receive something we cannot manufacture for ourselves: the grace to repent. That distinction changes everything....

If children need years of guidance and formation, then another question follows: what kind of relationship is capable of sustaining that responsibility? Aquinas’s answer is marriage. His argument is not simply that parents should ideally stay together, but that human nature itself points toward a stable, lasting union because raising a child is a long-term project. From there, he makes a further m...

Click here to become a paying subscriber. “If two consenting adults want to have sex, and they’re not hurting anyone, what’s the problem?” It’s one of the most familiar objections to the traditional Christian view of fornication. Aquinas’s answer takes the argument somewhere unexpected: look at the child. A human child needs far more than food, shelter, and schooling. Children need years of guidan...

An elderly couple can’t have children. Is their sexual relationship therefore sinful? If not, why would contraception be different? Part 2 takes that apparent contradiction seriously and follows Aquinas’s reasoning all the way through. The key turns out not to be whether conception actually happens, but whether we deliberately stand in its way. That distinction—between nature withholding an outcom...

If a sexual act cannot result in child-bearing, is it sinful? What happens when you ask AI to produce the strongest possible case against St. Thomas Aquinas? That’s exactly what this episode does. Starting with a modern philosophical critique, we explore the claim that sex has many legitimate purposes, that biology doesn’t create moral obligations, and that Aquinas’s reasoning simply doesn’t hold...

Modern debates about sex often begin with personal choice. Aquinas begins somewhere else entirely: with purpose. In this episode, he continues his exploration of lust by asking why different sexual acts belong in different moral categories. His answer isn’t based on emotion or social convention, but on what each act frustrates or damages. Some separate sex from its life-giving purpose. Others plac...

Why does Christianity distinguish between different kinds of sexual sins? Is it just tradition, or is there a coherent way of thinking behind it? In this episode, Aquinas argues that morality isn’t built on arbitrary commands. It’s built on understanding the purpose of sex. Before examining six different forms of lust, he explains the principle that makes those distinctions meaningful. Whether or...

“Hidden pride? Manifest lust.” - St. Josemaria Escriva. In Part 3, we answer the four challenges raised at the start, and discover something new: lust doesn't just wreck your thinking and your will. It takes over your speech. Saint Thomas walks through four kinds of broken speaking that come from lust. Obscene words spill out because a lustful heart fills the mouth. Scurrilous words rush out witho...

In the 1997 film, “The Devil’s Advocate”, lawyer John Milton (Al Pacino) is Satan tempting his son Kevin (Keanu Reeves) to join him in his ambition to rule Earth. Milton: Let me give you a little inside information about God. God likes to watch. He's a prankster. Think about it. He gives man instincts. He gives you this extraordinary gift, and then what does He do, I swear for His own amusement, h...

Saint Thomas teaches that every capital vice spawns a whole army of smaller sins in its wake — he calls them the “daughters” of that vice. In this three-part series, we’re examining the eight daughters of lust: blindness of mind, thoughtlessness, inconstancy, rashness, self-love, hatred of God, love of this world, and despair of the future. These aren’t random side effects — they flow directly fro...

Some bad habits arrive alone. Others bring an entire entourage. Aquinas calls these “capital vices”—the vices that lead the others. Lust, he argues, is one of them. Why does one compromise make the next one easier? Why does losing hope often make lustful temptation harder to resist? And why do certain desires seem to pull other bad decisions in behind them? This episode explores the relationship b...

Not every decision has the same consequences. Some choices affect only you. Others shape families, futures, and generations yet to come. In this episode, Aquinas tackles a question that sounds outdated but turns out to be surprisingly modern: Why are some desires more dangerous than others? His answer is both simple and unsettling. The more powerful a human act is, the more important it becomes to...

Most bad decisions don’t start with bad intentions. According to Aquinas, some desires have a unique power: they don’t just influence your choices—they can cloud your ability to reason in the first place. In this episode, we explore why lust has long been considered one of the most dangerous vices, what it means to act against reason, and why the real battle isn’t just about behavior—it’s about pr...

In this episode of Summa Made Simple , we explore one of the most challenging and frequently misunderstood questions in the Summa Theologiae : Is virginity more excellent than marriage? Drawing on Scripture, the Church Fathers, and the reasoning of St. Thomas Aquinas, we examine why the Church has traditionally regarded consecrated virginity as a higher state of life while at the same time affirmi...

What exactly makes virginity a virtue? In this episode of Summa Made Simple , we continue our exploration of chastity and virginity through a series of fascinating objections: If everyone begins life as a virgin, how can virginity be a virtue? If married people can become saints, does that not disprove virginity as a virtue? And if virginity can never be restored once lost, does that mean it diffe...

NOTE: This episode deals with adult themes and may not be suitable for younger audiences. Listener discretion is advised. Virginity sounds outdated, impractical, maybe even unhealthy. Aquinas knew these objections long before modern culture did. This episode explores a forgotten distinction that changes the conversation completely: virtue is not about avoiding extremes at all costs. It’s about dir...

NOTE: This episode deals with adult themes and may not be suitable for younger audiences. Listener discretion is advised. What happens when every craving gets treated like a command? According to Aquinas, that’s not freedom—it’s imprisonment. This episode explores chastity not as prudish rule-following, but as the struggle to keep reason in the driver’s seat when desire wants control. And it pushe...

“It just happened” is one of the most comforting—and dangerous—stories we tell ourselves. Because in reality, most outcomes are set in motion long before the moment things fall apart. This episode unpacks a hard truth: even if your awareness fades later, your earlier decisions still count. And they don’t just count—they carry forward into everything that follows. You’re not judged only by what you...

Common sense says the greater the chaos a vice causes, the worse it must be. Aquinas disagrees. This episode explores why drunkenness can be seriously sinful without being the gravest evil, and why some sins strike deeper than self-destruction. Along the way: intention, the hierarchy of goods, the devil’s “path of least resistance,” and a moral puzzle involving an assassin over drinks. Read the re...

Here’s a claim that sounds wrong at first: not all drunkenness is a sin. Drawing on Thomas Aquinas, this episode draws a hard line between what happens to you and what you choose to do . Because the real issue isn’t the state of being drunk—it’s the decision that got you there. We get into edge cases most people ignore: accidental intoxication, social pressure, responsibility for others, and why “...

Everyone argues about alcohol. Almost no one defines the real problem. Drawing from Thomas Aquinas, this episode cuts through the noise: alcohol isn’t inherently wrong—but losing control is. When reason gets pushed aside, everything else follows—bad decisions, damaged relationships, and avoidable regret. But here’s where it gets uncomfortable: sobriety isn’t equally easy for everyone. Age, tempera...
