Introduction

Obsessive-Compulsive Disorder (OCD) is a psychiatric condition characterized by unwanted intrusive thoughts (obsessions) and repetitive behaviors or mental acts (compulsions) aimed at reducing distress. For Catholics, the lived experience of OCD can be especially complex, because questions of morality, religious practice, and spiritual identity can often become entangled with the disorder. This can be especially painful because obsessions and compulsions can touch what is at the very core of a person’s faith and moral life. It is therefore essential to draw a distinction between two categories: Catholics who live with OCD in general, and individuals whose OCD symptoms specifically involve religious or moral themes. This distinction matters not only for clarity in clinical practice but also for pastoral care within the Church. When therapists, priests, or family members misunderstand the difference, well-intentioned guidance can unintentionally reinforce compulsive cycles or increase spiritual anxiety.
Catholics with OCD
The first group consists of Catholics who experience OCD symptoms that have little to do with their religious faith. A Catholic may struggle with contamination fears, excessive checking, symmetry, or intrusive violent images without any religious content. For instance, a Catholic accountant may repeatedly check that a spreadsheet has saved correctly, or a Catholic parent may experience intense fears of harming their child. Their faith is an important part of their life, but their OCD operates partly, largely, or entirely outside of that context.

For these individuals, treatment looks very similar to standard evidence-based approaches for OCD. Cognitive therapy and Exposure and Response Prevention (ERP) help reduce compulsions and reframe obsessive fears. The Catholic identity of the patient remains significant, however, because therapy should integrate their values and respect their conscience. A therapist who recognizes the centrality of faith can frame treatment in ways that harmonize with Catholic teaching on the dignity of the human person and the call to holiness.
OCD with Religious or Moral Themes
The second group includes those whose OCD symptoms manifest with religious or moral content. OCD symptoms in this group may include blasphemous or sacrilegious thoughts, doubts about the sincerity of ones belief in God, uncertainty about having fully or adequately repented of sin, worry about having confessed sins ‘improperly,’ fear potentially having committed a mortal sin, etc. Some people in this group may spend long periods of time wondering if they are in a state of grace or whether they have been contaminated by moral or spiritual impurity. Still others may experience pathological scrupulosity, especially if obsessive-compulsive dynamics revolve around moral or ethical concerns and content. Individuals in this group can experience compulsions that take the form of excessive confession, repetitive prayers, or avoidance of anything perceived as spiritually triggering or dangerous. Regardless of symptom content, it is important that these individuals know that these issues are not signs of a weak faith or spiritual failure. Rather, they are symptoms of OCD attaching themselves to what is most important in a person’s life.
Scrupulosity in particular has been recognized in Catholic tradition for centuries. Spiritual writers from St. Ignatius of Loyola to St. Alphonsus Liguori offered guidance to souls caught in cycles of excessive doubt. Yet modern clinical research shows that pathological scrupulosity is not primarily a moral failing or lack of faith but rather a form of OCD.
Moral Teaching and OCD
Catholic theology offers clarity that can reduce the burden of OCD. The Catechism of the Catholic Church teaches that freedom is central to moral responsibility: “Freedom is the power, rooted in reason and will, to act or not to act… so that he might seek the Creator of his own accord” (CCC, 1731). Yet, it also affirms that human freedom is wounded by sin and psychological influences (CCC, 1739). This means that intrusive thoughts or compulsive behaviors often diminish freedom and therefore do not carry the same moral weight as deliberate sin. In some cases moral culpability may even be minimal to nonexistent.
Mortal sin, according to the Catechism, requires grave matter, full knowledge, and deliberate consent (CCC, 1857). In the case of OCD, the presence of full knowledge is highly suspect—as OCD demonstrably and measurably can distort a person’s perception of reality. This is usually not to a degree that one can see with schizophrenia spectrum disorders, but it can be significant and lead to genuine confusion. In the case of OCD, the presence of deliberate consent is even more highly suspect—as OCD undermines consent because the thoughts and impulses are (by their very nature) intrusive and unwanted.
In Amoris Laetitia, Pope Francis cautioned against rigorism that “obscures the primacy of love and grace” (AL, 311). Similarly, St. John Paul II encouraged Catholics to entrust themselves to Divine Mercy: “Do not be afraid to abandon yourselves totally to His love” (Novo Millennio Ineunte, 58). These teachings directly counteract the distorted picture of God presented by OCD, where He is imagined as harsh, legalistic, and eager to condemn minor imperfections.
Clinical and Pastoral Implications
When clinicians recognize whether OCD is faith-neutral or faith-involved, they can provide more accurate care. Catholics with general OCD can benefit from standard ERP and cognitive therapy. Catholics with OCD that is faith-involved (e.g., marked by scrupulosity) may require interventions that are more nuanced and more significantly informed by theology and philosophy—compared to OCD that is more faith-neutral. Catholics with OCD that is faith-involved may also benefit from the additional integration of pastoral guidance and catechetical clarity. For example, when a patient repeatedly confesses the same minor sin, the therapist might gently ask, “What does the Church actually teach about mortal versus venial sin? Does your behavior fit that teaching, or is OCD making the rules harsher?” This question invites the patient to compare OCD’s distorted demands with Catholic doctrine.
Clergy can also play a crucial role in recovery. For example, a confessor aware of OCD that is faith-involved or associated with pathological scrupulosity can set boundaries, such as limiting confession frequency, cautiously offering reassurance (that is unlikely to reinforce underlying obsessive-compulsive dynamics), as well as encouraging trust in God’s mercy over justice. Priests can also collaborate with therapists to ensure that spiritual guidance supports therapeutic goals.
Conclusion
Distinguishing between Catholics who have OCD and those whose OCD manifests in religious themes allows both clinicians and pastors to provide more compassionate and effective care. The Church teaches that intrusive thoughts and compulsive behaviors are not sins in themselves, and because of this therapy grounded in Catholic values can help restore freedom that OCD may have eroded. Catholics struggling with OCD can find hope in the words of St. John Paul II: “Man cannot live without love. He remains a being that is incomprehensible for himself, his life is senseless, if love is not revealed to him” (Redemptor Hominis, 10). OCD may distort faith, but Christ restores it through mercy, love, and truth.
