The best books with themes of theological horror

Who am I?

I was a fraternal twin, and my brother died about two hours after birth from a bilateral pulmonary hemorrhage. Knowing this as a child, I became fascinated with death, thinking of it as annihilation. Later, I feared my religion (Christianity) might be false and I would be annihilated at death. Thus I became fascinated by all things philosophical and theological, including theological horror. The works I like most center on themes of the truth of religion and life after death while avoiding preachiness and the trap of telling rather than showing.

The books I picked & why

The Taking

By Dean Koontz,

Book cover of The Taking

Why did I love this book?

I highly recommend The Taking because it continues to haunt me with existential terror—I have never been as frightened by a horror novel in my life. The struggles of a young couple in the face of an apparent alien invasion are frightening enough, but the imagery is overwhelmingly frightening and powerful. When the reveal comes at the end, the surprise was almost too scary to bear, since it concerns entities in which I truly believe. This book lingers with me… and lingers…. and lingers….

What is this book about?

A luminous silvery downpour is drenching their small California mountain town. It has haunted their sleep, invaded their dreams, and now, in the moody purple dawn, the young couple cannot shake the sense of something terribly wrong.

    As the hours pass, Molly and Neil listen to disturbing news of extreme weather phenomena across the globe. By nightfall, their little town loses all contact with the outside world. A thick…


By William Peter Blatty,

Book cover of Legion

Why did I love this book?

I prefer this book to Blatty’s The Exorcist. The story of the return of a character from the original story who happened to be thoroughly dead, of demons more powerful than Pazuzu of The Exorcist, of the seemingly magical ability of the possessed to escape detection after murdering people lend a sense of creepy mystery to the book. Blatty is obsessed with the possibility of death being annihilation, and this is also my greatest fear. The level of sophistication in the discourse is exceptionally high for a horror novel, but this does not detract from the terror or the powerful climax of the book.

What is this book about?

From the author of The Exorcist -- Legion, a classic tale of horror, is back in print!

A young boy is found horribly murdered in a mock crucifixion. Is the murderer the elderly woman who witnessed the crime? A neurologist who can no longer bear the pain life inflicts on its victims? A psychiatrist with a macabre sense of humor and a guilty secret? A mysterious mental patient, locked in silent isolation?

Lieutenant Kinderman follows a bewildering trail that links all these people, confronting a new enigma at every turn even as more murders surface. Why does each victim suffer…

Imaginary Friend

By Stephen Chbosky,

Book cover of Imaginary Friend

Why did I love this book?

This is one of the books that made me wonder at the world. What begins as a conventional story of a boy haunted by an “imaginary friend” turns into something far more complex and frightening. For most of the novel I had no idea of a theological element in the book, so when that element hit it was a surprise, at least to me. The effect reminded me of Rudolf Otto’s description of meeting a supernatural being as “mysterious, tremendous, and fascinating”—I was pulled in even as I was drawn away.

Book cover of Ancestral Shadows: An Anthology of Ghostly Tales

Why did I love this book?

As I read this collection of ghost stories, a sense of awe, wonder, and even joy, came into my mind and heart. These stories are better than those of M. R. James—the twist at the end of each story made me literally chill. Kirk’s world is a Christian world, but he is never preachy, focusing on the storyline. Like Poe, the single effect in the stories is stunning, surprising the reader with marvels and an expanded view of the world.

What is this book about?

Foreword by Vigen Guroian

Widely regarded as the founder of the modern conservative movement, Russell Kirk was a noted man of letters whose prodigious literary career included a syndicated newspaper column and a regular page in National Review. This volume demonstrates another compelling side of Kirk — the imaginative author who could communicate his powerful vision through the dramatic genre of the ghost story.

Ancestral Shadows collects nineteen of Kirk's best ghostly tales from periodicals and anthologies published throughout his life. In the tradition of Defoe, Stevenson, Hawthorne, Coleridge, Poe, and other master writers, these frightful stories conjure the creaks…


By Stephen King,

Book cover of Revival

Why did I love this book?

As someone seeking proof of an afterlife to strengthen my faith, I have an affinity for the ex-preacher in this novel who uses electricity to contact the realm of the dead. Hating God and heartbroken over the death of his wife, he wants to find her in the afterlife, should there be one. The main character journeys from childhood to adulthood, meeting the preacher as a child and then, as an adult, he runs into the former preacher. He witnesses the final experiment that reveals a conclusion that is a complete surprise.
