Well, Catholics do write spec fiction and have written it. For example, think of Michael D. O’Brien, Dean Koontz, and J. R. R. Tolkien.
Spec is an abbreviation for speculative, and it refers to the major categories of science fiction, horror, and fantasy. But not all spec fiction is alike, and reader discretion is advised.
I enjoyed The Father Capranica Mysteries: Stories of the Strange and Supernatural by Father Mike Driscoll. His character time travels, which is something that God initiates. Father Capranica finds himself in places throughout history where God has a task for him. The stories are fast-paced, varied, entertaining, and faith affirming.
The fact that a priest wrote “stories of the strange and supernatural” encouraged me regarding my fiction. It also made me realize that I could revise my work to include Catholic elements instead of things that are not Catholic. I think the villains in stories can do all sorts of very evil things, but usually not the protagonists, unless they’re in the process of reforming. However, I don’t think authors should give many details about the occult, such as specifics about witchcraft.
The first book I revised, The Wolf’s Daughter, I renamed The Wolf’s Enemy. I changed the identity of the protagonist’s next-door neighbor from a witch to a cat rescuer. Tala, the main character, has an amulet that’s a family heirloom, but I have a relative destroy it as he voices harsh words about the pagan object. He reveals a Catholic holy object but warns her against using it as a magical talisman. Instead, he prays with her and explains that healing requires faith and depends on God’s will. I allowed the antagonist to remain as evil as he had been in the original version.
While revising the book, I thought about things such as prophecy, holy objects, and God’s signs in the sky. Reflected in a dark mirror, they’re twisted into sinful things, such as fortune-telling, amulets, and astrology.
Spec fiction is entertaining and popular. The stories often deliver a powerful emotional experience that could change a person on a more profound level than just an appeal to the intellect. Well-written spec stories that are not the reflection from a dark mirror can have a positive influence on a person’s faith journey.
