Catholic Horror (better known as Religious Horror ) is a literary genre that utilizes Roman Catholic themes, imagery, and symbolism. It incorporates elements such as exorcisms, demonic possessions, rituals, supernatural events, occult practices, and depictions of the Devil. This subgenre of horror primarily manifests in cinema and literature.

Media within this genre often portrays settings where traditional Catholic values are prominent, frequently within countries historically associated with Roman Catholicism. Catholic Horror also integrates architectural and cultural elements linked to these regions, notably Gothic architecture , cathedrals, and regional religious legends. The origin of this genre is traced to the late 1960s, with Rosemary's Baby (1968) cited as an early example. This subgenre is associated with the Satanic Panic and has influenced the Morute aesthetic.

Films like The Exorcist (1973) are considered foundational to the genre, establishing the use of Catholic dogma against demonic forces. The genre deals with themes of faith versus doubt, the nature of good and evil, and the potential for corruption within religious institutions. It frequently utilizes religious iconography, such as crucifixes and holy water, as both symbols and weapons against supernatural threats. The representation of Catholic rituals and figures, including priests and exorcists, is central to the narrative, often depicting their struggles against demonic entities. The genre also examines the psychological impact of religious belief and the fear of the unknown, particularly in relation to Catholic doctrine.

The subgenre of Catholic Horror exhibits a history rooted in both literary and cinematic works, characterized by the integration of Roman Catholic theology and philosophy within narratives of horror . Literary examples, such as the novels of Robert Hugh Benson, J-K. Huysmans, and Georges Bernanos, as well as Dante Alighieri's Inferno , show a tradition of employing Catholic cosmology and ontology to explore themes of good and evil. These works, alongside William Peter Blatty's The Exorcist , engage with philosophical and spiritual inquiries through dialogues and thematic explorations, often depicting conflicts between faith and doubt, and the nature of evil.

Cinematic representations of Catholic Horror, including films like Rosemary's Baby (1968), The Exorcist (1973), and The Omen (1976), utilize Catholic rites and symbols, such as exorcisms and crucifixes, to depict confrontations with demonic entities. The Exorcist (1973), directed by William Friedkin, is a significant film in the genre's development. This film, alongside others, contributed to the genre's growth, inspiring further productions that blended horror elements with Catholic themes. The genre's cinematic development includes works that explore the psychological and theological dimensions of possession and demonic influence, often within settings that emphasize the authority and structure of the Catholic Church. The genre draws inspiration from the history of Catholic exorcisms and beliefs regarding supernatural entities.

In recent years, there has been a resurgence of films and television series within this subgenre, with notable films such as The Nun II (2023) and Heretic (2024) contributing to its renewed popularity.

Catholic Horror draws inspiration from a distinct set of religious and philosophical elements. The subgenre frequently employs Catholic symbols and rituals, such as crucifixes, holy water, and exorcisms, to depict confrontations with evil. These visuals serve to establish a sense of spiritual conflict and emphasize the power of faith against demonic forces, often highlighting the vulnerability of humanity in the face of overwhelming supernatural threats.

Narratives often feature dialogues that resemble philosophical debates, reminiscent of Platonic dialogues or Christ's temptations. These conversations, sometimes between characters and demonic entities, explore theological and philosophical themes, such as the nature of good and evil, the existence of God, and the limits of human understanding, adding a layer of intellectual dread to the horror. The contrast between theological arguments and visceral horror creates a unique tension.

Grisly and solemn representations are common, with stories often ending in tragedy rather than simple resolutions. This approach contrasts with more optimistic Christian fiction, pointing out the potential for suffering and moral ambiguity within a religious context. The emphasis on tragic elements like death, despair, and the potential for moral corruption within religious institutions also shows the genre's exploration of the darker aspects of faith.

Cinematic portrayals frequently utilize settings that emphasize the authority and structure of the Catholic Church, such as imposing cathedrals, ancient monasteries, and isolated parishes, creating a backdrop for the supernatural events. The use of specific religious iconography and rituals aims to create a sense of authenticity and heighten the horror for viewers familiar with these elements. The juxtaposition of sacred spaces with profane acts contributes to the subgenre's unsettling atmosphere.

The visual style can also incorporate elements of classical art and literature, reflecting the subgenre's connection to the classical liberal arts tradition and its use of philosophical and theological concepts. This connection can be seen through references to works like Dante's Inferno , which provides vivid imagery of hell and moral struggle. The incorporation of classical imagery and literary references adds depth and complexity to the visual narrative, grounding the supernatural horror in established cultural and artistic traditions.

Catholic Horror has faced criticism for several reasons. Some critics object to how religion is portrayed in these films. Sam Acosta, in a review, observes that some Christians generally reject horror, citing biblical texts that oppose such depictions. Online discussions also indicate that some viewers find the "preachy" elements in certain Catholic Horror films disruptive, perceiving them as "religious propaganda." This can detract from the viewing experience for those who do not share those beliefs. Furthermore, the subgenre's focus on Christian, and specifically Catholic, themes can alienate those from different religious or non-religious backgrounds. Some viewers desire horror narratives that explore other religious or cultural contexts.

The prevalence of Catholic imagery in horror films is noteworthy given that topics of religious reverence are generally handled with caution in the film industry. Despite historical discrimination faced by Catholics in the United States, which might typically qualify them for "oppression points" within some frameworks, Hollywood appears willing to use Catholic themes for horror. This contrasts with a noticeable avoidance of Islamic imagery in horror films, which may be due to practical reasons, including potential violent responses to such depictions.

The subgenre gained significant momentum with the success of The Exorcist (1973), which grossed over $400 million through re-releases and theatrical runs. This film depicts demonic possession, a concept with biblical roots, which some religious individuals might find less sacrilegious, although they could still object to its presentation or purpose. The Exorcist spawned sequels, including The Exorcist II (1977) and The Exorcist III (1990), and inspired other Catholic Horror films such as Omen (1976), Prince of Darkness (1987), The Day of the Beast (1995), The Nun (2018), and Immaculate (2024). The film Immaculate , for instance, features actress Sydney Sweeney in the role of a nun, a casting choice that some devout Catholics might find problematic due to her prior work.

However, the association between Catholicism and the macabre predates modern cinema. Examples include European Catholic "bone churches" such as the Capuchin Crypt in Rome, Italy; the Capela dos Ossos in Evora, Portugal; and the Sedlec Ossuary in Kutná Hora, Czech Republic, which are decorated with human bones, sometimes those of former monks. Many Catholic churches are built in the Gothic style, exemplified by Notre Dame in Paris, France, and feature gargoyles, small grotesque sculptures believed by some scholars to represent evil or ward off evil spirits. Additionally, renowned Catholic artists, like Albrecht Dürer in the 16th century, depicted images of demons or the apocalypse in their works. However, these historical examples emerged from a time when religion was deeply integrated into daily life, and the symbolism was not merely for aesthetic shock value. In contemporary filmmaking, some critics argue that the use of Catholic imagery often amounts to superficial "cultural appropriation."
