The Catholic Scrupulosity Assessment

St. Alphonsus Liguori (1696–1787)

If you've ever walked out of confession feeling worse than when you walked in, St. Alphonsus Liguori is the saint who would have had something to say about your confessor.

Alphonsus was an 18th-century Italian priest, theologian, and founder of the Redemptorists — eventually named a Doctor of the Church, one of only 37 in all of Catholic history. But what set him apart wasn't his brilliance. It was his pastoral instinct. At a time when moral theology was dominated by Jansenism — a harsh, rigorist strain that treated every ambiguous situation as probably sinful and viewed the scrupulous conscience as just needing to try harder — Alphonsus pushed back. Hard.

He spent decades studying, writing, and arguing that the Church's job was not to crush consciences but to form them. His Theologia Moralis became the most widely used manual in Catholic moral theology for over a century. Confessors across the world were trained on it.

And in the middle of that massive work, Alphonsus dedicated an entire section specifically to the scrupulous person — not as a moral failure to be corrected, but as someone requiring a specialized approach that most spiritual directors were getting completely wrong.

He is, in short, the closest thing Catholicism has to a clinical authority on scrupulosity — eight centuries before the DSM existed.

When he speaks on this, he's not offering an opinion. He's speaking as the Church.

If St. Alphonsus Liguori laid the theological foundation for understanding the scrupulous conscience, Father Thomas Santa is the man who's been doing the pastoral work on the ground for the last several decades.

Father Santa is a Redemptorist priest — ordained in 1978, which means he carries on the same order Alphonsus himself founded. He served for years as the priest-director of Scrupulous Anonymous, the Redemptorist newsletter that has been ministering specifically to people with scrupulosity since 1964. He's also a former director of the Redemptorist Renewal Center in Tucson, and the author of multiple editions of Understanding Scrupulosity, the most widely used Catholic pastoral resource on the topic — now in its fourth edition, published 2025.

More than twenty years of retreats for scrupulous Catholics. More than twenty years of workshops training the priests, pastoral ministers, and therapists who work with them.

He's not theorizing. He's heard the questions — about confession, about sin, about what happens in your head at 2am when you can't stop replaying the same doubt — and answered them, repeatedly, in print, in person, and one-on-one, for longer than most online therapists have been practicing.

He also makes one thing clear from the start: he is not scrupulous himself. He says this without apology. Which, if you think about it, is exactly what you want. A good guide isn't someone who's still lost — it's someone who knows the terrain, has walked people through it thousands of times, and can tell you what the path actually looks like from the outside.

Religious OCD (sometimes called scrupulosity — especially by us Catholics) is a specific subtype of Obsessive-Compulsive Disorder in which the content of a person's obsessions and compulsions centers on religious, moral, or ethical themes. It shows up across every major world religion, and it has been documented for centuries. What you're dealing with isn't new, and it isn't unique to you.

What it actually is

OCD is a disorder organized around two things: obsessions and compulsions. Obsessions are intrusive, unwanted thoughts, images, or urges that feel threatening and won't go away. Compulsions are the behaviors — mental or physical — that a person performs to try to reduce the anxiety caused by those obsessions. The temporary relief they provide is real, but short-lived. And each time a compulsion "works," it trains the brain to treat the original obsession as a genuine threat — which makes the whole cycle worse over time.

In Religious OCD, the obsessions attach to things that matter deeply to you: sin, salvation, confession, God's judgment, purity, prayer, motive. The compulsions follow the same pattern — repetitive confession, excessive reassurance-seeking from priests or family members, mental review of past actions, compulsive prayer, avoidance of church or Scripture to prevent triggering thoughts.

What makes it OCD and not just being devout

This is the question most people with scrupulosity spend years asking. The answer isn't about how much you care — plenty of devout, faithful people care deeply about sin and holiness without this disorder. The difference is function.

A devout person might have a troubling thought, sit with some discomfort, and move on. A person with Religious OCD gets stuck in a loop. The thought won't resolve. More information doesn't settle it. Confession doesn't bring lasting peace — it brings brief relief followed by a new doubt. The goal stops being faithfulness and becomes certainty, and certainty is the one thing OCD will never actually deliver.

Put plainly: a tender conscience responds to instruction and reassurance. OCD does not. If it did, you'd have stopped doing this by now.

What treatment looks like

The gold standard treatment for OCD — including Religious OCD — is Exposure and Response Prevention therapy, or ERP. It works by doing the opposite of what the disorder demands.

Rather than avoiding the thoughts or performing compulsions to make them go away, ERP involves gradually and deliberately facing the feared thoughts, images, or situations — and then resisting the urge to respond with a compulsion. Over time, the brain learns that the obsession is not actually a threat, that anxiety will naturally decrease without a ritual to manage it, and that you can tolerate uncertainty without your spiritual life falling apart.

For Catholics specifically, this often means things like reducing confession frequency, sitting with unresolved doubt without seeking reassurance, and learning to distinguish between a genuine act of faith and a fear-driven compulsion that looks like one.

It is hard work. But it is the treatment with the strongest evidence base, and for many people, it produces significant, lasting relief.

If you're curious whether what you're experiencing might be Religious OCD, or if you want to pursue treatment, consider reaching out to a licensed mental health professional with experience in OCD. This is a treatable condition — and you don't have to figure it out alone.

After working with scrupulosity for several years, I began noticing that the men I saw weren't all struggling in the same way — they were struggling in recognizable patterns. Anecdotal observation is a starting point, but I wanted something more rigorous. I analyzed over 200 anonymous questions submitted to Father Santa's Scrupulous Anonymous mailbox, cross-referenced with the most current academic research on OCD and religious scrupulosity, and what emerged were nine distinct patterns I came to call The Nine Archetypes.

1. The Auditor: Constantly reviewing past actions, intentions, and interior states in search of a sin he might have missed — invisible to everyone around him, exhausting to live inside.
2. The Repeat Penitent: Returns to confession again and again for the same absolved sin, because the sacrament keeps delivering absolution but never delivering certainty.
3. The Canon Lawyer: Treats every moral question as a knowledge deficit to be researched until closed — but a clear answer only opens the next question.
4. The Ledger-Keeper: Tracks specific moral debts — apologies owed, restitution due, obligations unmet — that never feel fully discharged no matter what he does.
5. The Self-Sentencer: Keeps himself under a sentence no confessor assigned; guilt fading feels like insufficient sorrow, so he regenerates it compulsively.
6. The Ritual Repeater: Prayers and practices must be completed a certain way or started over — not by any external standard, but by a felt sense the disorder controls.
7. The Quiet Avoider: Has slowly narrowed his life around perceived near occasions of sin, sometimes including the sacraments themselves.
8. The Asker: Seeks reassurance from priests, spouses, friends, forums, and anyone who will answer — recruiting others into a pattern that gives temporary relief and permanent return.
9. The Ambushed: Unwanted blasphemous, sexual, or violent thoughts arrive without warning, especially in sacred moments, and he reads his horror at them as evidence of consent.
