Books reading recommendations Exploring Faith and Fear in Nine Religious Horror Novels Stories of corrupt clergy, cult rituals, demons, dogma, and denial. By Sam Reader | Published on March 17, 2026 Comment 0 Share New Share Religion has always been fertile ground for horror. Numerous horror and fantasy novels are set in their winding passages and catacombs of ancient churches and sacred sites, but even beyond that, there are all the darker elements one might encounter—from angels, demons, and gods fighting over the souls of humanity or corrupt institutions and individuals using faith as a pretext for “we can do what we want” to byzantine ceremonies that often have even more byzantine consequences and omniscient beings that humans can’t look upon without going insane. All of these lend themselves to unnerving and often terrifying fiction—with this in mind, here are nine novels that explore the disturbing side of cults and churches, rites and rituals, hypocrisy, belief, and those who claim to speak for a higher power. The Priest by Thomas M. Disch Disch’s meta-Minneapolis quartet (The Businessman, The M.D., The Priest, and The Sub) was an attempt to bring the gothic into the modern day, and with The Priest he did it upsettingly well while also skewering the Catholic Church for abuses that had yet to be widely discussed and reported at the time. Father Brice, the titular priest, is introduced helping his elderly mother as she suffers from dementia and managing his Minneapolis parish before heading out for the evening to get Satan tattooed on his chest. Brice is a man hiding from his past as an alcoholic and a pedophile, blackmailed for his former deeds by a number of people who assign him a variety of strange tasks. Disch’s lurid, disturbing, and blackly comic story about the lengths a man will go to avoid atoning for his sins soon spirals into a web of backroom scheming, occult practice, and murder, casting the Catholic clergy of Minnesota as a pit of vipers willing to do anything to hang on to their ill-gotten peace. Legion by William Peter Blatty An existentialist meditation disguised as a suspense novel, Legion is centered around Kinderman, a police lieutenant who finds a young boy murdered on a dock with the calling card of a long-dead serial killer on his wrist. As bodies pile up and an old enemy seemingly back from the dead, it falls to Kinderman to fight for what little good he sees in the world. Blatty’s follow-up to The Exorcist is weirder and strikes a better balance between grim humor, religious conflict, and upsetting visuals than its predecessor (no shock to anyone who saw Blatty’s Exorcist III, based on this book), mostly because Blatty absolutely nails Kinderman’s world-weary commentary on death and evil. The result is both bleak and somehow relentlessly entertaining. Between Two Fires by Christopher Buehlman It’s been said before that hell is the absence of god, and it’s harder to conceive of a place more removed from god than Europe during the Black Plague. Between Two Fires is a postapocalyptic fantasy set in 1300s France, where a fallen knight saves a little girl from his bandit companions and takes it upon himself to protect her as she journeys across the blasted countryside following directions given to her by “angels.” Anyone familiar with medieval horror knows at least a little of what they’re in for, but between the gnarliest depictions of demons outside a Persona game and the bleak horror of a landscape (presumably) abandoned by the deity, Buehlman’s horror takes a disturbing turn toward the cosmic and religious. The Unworthy by Agustina Bazterrica, translated by Sarah Moses From the moment Agustina Bazterrica’s novel opens, it’s clear that something is very wrong in the convent where its narrator is cloistered. There’s talk of “contamination,” three people sing a hymn until they begin to bleed, and the narrator witnesses a ritually mutilated member of the Church who starts orating words from another plane of existence. In a style that’s uniquely Bazterrica, the details filter in, the colloquial names for everything and the terrifying commonplace existence in the House of the Sacred Sisterhood illustrating just how wrong the world truly is. Through the narrator’s secret journal, we’re introduced to a world thrown into ecological chaos and ruled by a bizarre religious cult with many of the trappings of Catholicism, beset by toxic haze and the devotees of a god who seems more cosmic horror than cosmic being. It’s a disturbing look at faith and trauma as only Bazterrica can construct. Father of Lies by Brian Evenson Fochs, a provost of a Christian offshoot colloquially known as “the Bloodites,” is sent to a therapist at the urging of his wife. She claims that he sleepwalks, narrates disturbing dreams, and speaks in a voice not his own. Through the sessions with Dr. Alexander Feshtig, Fochs reveals in excruciating detail his “loud thoughts,” a series of depravities and atrocities he often dreams of committing, mostly against the children of his congregation. As Feshtig discovers that some of these “loud thoughts” are connected to crimes that took place outside of Fochs’ head, Evenson slowly builds a character study of a man whose monstrous acts were shaped, nurtured, and protected by his church. As the point of view switches to Fochs, the book becomes even more disturbing, as Fochs sincerely believes at least some of the scripture he spouts. It’s an uncomfortable exploration of abuse, patriarchy, and religious hypocrisy through the lens of a man who is surrounded by and able to weaponize those things, just the way he was taught. Everything the Darkness Eats by Eric LaRocca In the small town of Henley’s Edge, people are disappearing, led to their uncertain doom down in the basement of Heart Crowley. A man with a compelling voice and a horrifying secret tied to his unnerving interpretation of religion, Heart is just the most prominent of the evils in Henley’s Edge, a town awash in violence, homophobia, and further mounting tensions. Standing against him are a widower with a strange spirit of his own, a mother and her daughter, and two police officers investigating the serial disappearances. LaRocca’s novel is a masterpiece of tension and small-town terror where a deep sense of empathy, sympathy, and impending doom circles ever closer to the protagonists, ratcheting up the horror even before the violence, brutality, and Heart’s plans for the thing in his basement reach their peak. The Possession of Alba Díaz by Isabel Cañas Alba Díaz and Carlos Monterrubio enter into a marriage of convenience—Alba to escape her family, Carlos because he’s not interested in women, period; both are desperate get out from under their overbearing families in the silver-mining town of Zacatecas. When their families are forced to move out of town due to plague and into the shadow of the silver mine tying all their fates together, something within Alba stirs, catching the attention of her in-law Elias, an occultist and alchemist. Cañas’ novel kicks off gorily, expertly weaving together multiple strains of Mexican gothic into a dark family saga of faith, demons, magic, and generational trauma centered around a single complex heroine. Mother-Eating by Jess Hagemann Told in the style of a true-crime documentary with a touch of grindhouse transgression, Mother-Eating is a retelling of the story of Marie Antoinette, this modern version christened Mary Toni Habsburg and sold off to her own King Louis, the head of the Christian torture-and-sex cult Simon’s Sorrow. A curious child with a weird relationship to God, Mary Toni cuts an odd figure through the narrative as adults imprint on her, force her to carry the burden of their desires and emotions, and proclaim her their twisted messiah. Hagemann’s satire of social politics, celebrity, and parasocial relationships can take some getting used to, but it’s a lurid, viciously funny tale all the same. The Body by Bethany C. Morrow It would be easy to call this a thriller about religion and marriage, but that would be doing this novel a disservice. From the opening pages, the true horror of Morrow’s work slams into the reader like Bethany’s car in the first chapter’s hideous pileup—a tangled mass of trauma, self-loathing, and outright fear running through Mavis’ head as she thoroughly believes she’s being sent to Hell for somehow disappointing her husband, only to end with “he was afraid of losing her, too. Everything would be all right now.” It’s this tense, churning internal conflict that underscores the violent attacks and cultlike behavior—the intrusive thoughts and trauma that have been inflicted upon Mavis through by her previous bad marriage and the congregation she was raised in—that makes The Body such a harrowing and riveting read in places. Religious horror, as Morrow understands, isn’t always just about god—it’s about the death grip that belief systems, and the internalized fears and shame they’ve seeded within you, can maintain on your brain even after you turn fully away from that church or creed.[end-mark] The post Exploring Faith and Fear in Nine Religious Horror Novels appeared first on Reactor.
