The Mysteries of Evil

Where did the
spirits come from?

Pieter Bruegel the Elder, The Fall of the Rebel Angels, 1562
The Fall of the Rebel Angels Pieter Bruegel the Elder · 1562

Demons, ghosts, exorcisms. What did ancient Jews and Christians really believe about the supernatural? The Bible is full of spirits, from Satan and demonic possession to ghostly encounters and divine prophecy, and almost none of it works the way later tradition assumes.

Where did the ideas of demons and ghosts come from? How did they evolve in Jewish and Christian thought? This course traces the supernatural beings that shaped early religious imagination, from the fallen angels behind the origin of evil to the chief demon we now call the devil.

From the exorcisms in the gospels to the ghost of the prophet Samuel, Travis Proctor follows how ancient people understood their encounters with spirits, and how those beliefs transformed over time. The result is stranger, older, and far more human than the story we inherited.

Specialty

Demons & Early Christianity

From fallen angels
to the ghost
of the risen Jesus.

Six Themes

Twenty-six lectures gathered into six themes: the origins of the demonic, the rise of Satan, the demons of ancient Judaism, the spirits of the gospels, and the long history of biblical ghosts.

Theme I

The Spirits of the Bible

What is a demon, and what is a ghost? Where do these ideas come from, and what does it mean to study the supernatural of the Bible in an academic setting?

Introduction
Theme II

Fallen Angels

Before there were demons, there were fallen angels: heavenly beings who descended to earth, revealed forbidden knowledge, and, for ancient writers, explained the origin of evil itself.

The Origins of Evil
Theme III

The Rise of Satan

How the satan went from a prosecutor in God’s heavenly court to the chief demon, the devil: Satan in early Christianity, his abode in hell, and his end-times agent the antichrist.

The Chief Demon
Theme IV

Demons of Ancient Judaism

Azazel, Lilith, and the malevolent spirits of the ancient Near East, and the remarkably rich demonology, and exorcism, preserved in the Dead Sea Scrolls.

Near Eastern Spirits
Theme V

Demons in the Gospels

Possession and exorcism in the New Testament, demons and disease, demons and magic, spirits of divination, and the “powers and authorities” of Paul: the demonic world Jesus moved through.

The New Testament
Theme VI

Ghosts & the Dead

Ancient ghost stories, the household spirits of the Hebrew Bible, the ghost of Samuel raised at Endor, the Holy Ghost, and the risen Jesus his own followers mistook for a spirit.

Scholar of Early Christianity · Ph.D., UNC-Chapel Hill

A first-generation college graduate and scholar of the Bible and early Christianity, Travis Proctor received his Ph.D. in Religious Studies from UNC-Chapel Hill, specializing in ancient Mediterranean religions. His teaching and research draw from interdisciplinary fields like religious studies, environmental history, animal studies, space and material culture, and ritual studies. His first book, Demonic Bodies and the Dark Ecologies of Early Christian Culture (Oxford University Press), explored how early Christian theorizations of demonic bodies influenced ancient understandings of cosmic “ecosystems,” and how such historical perspectives may inform contemporary environmental ethics.

His work has appeared in academic journals such as the Journal of the American Academy of Religion, Journal of Early Christian Studies, Harvard Theological Review, and the Journal of Ecclesiastical History, as well as public venues including Bible Odyssey, Religion for Breakfast, Religion Dispatches, The Bart Ehrman Blog, and the “Tell Me Something I Don’t Know” podcast. He lives in Ohio and enjoys hiking outdoors, a good round of disc golf, and watching Kansas City Chiefs football (even before Taylor Swift!).

Prepare to Rethink

Common assumptions
this course will challenge.

Common Assumption

Satan is the devil from the very first page of the Bible.

In fact

In the oldest texts “the satan” is a prosecutor in God’s heavenly court, not the cosmic enemy. The devil we picture was assembled across centuries of Jewish and Christian thought.

Common Assumption

The serpent in Eden was obviously Satan.

In fact

The story of Adam and Eve never names Satan, and many scholars doubt the connection was there originally. Reading the devil back into Genesis is itself a later development.

Common Assumption

Hell, ruled by Satan, comes straight from scripture.

In fact

The fiery hell with Satan presiding is a late composite. Its pieces were gathered slowly, and the Bible’s own picture of the afterlife is far less tidy than the tradition.

Common Assumption

Ghosts are a modern superstition, not a biblical idea.

In fact

The Hebrew Bible has the ghost of Samuel and household spirits of the dead; the gospels have a risen Jesus his followers take for a ghost. The dead were very much present in the biblical world.

What is a ghost, and where does the idea come from? The ancient roots of our modern concept, the surprising consistency of belief, and the classic ancient ghost stories.

23 Ghosts, Sheol, and “Teraphim” in the Hebrew Bible Lesson 23 · Ghosts & the Dead

The teraphim, household gods thought to be images of deceased ancestors. How these revered family ghosts likely figured in ancient worship, and how biblical authors later condemned them.

24 The Ghost of Samuel and the Witch of Endor Lesson 24 · Ghosts & the Dead

One of the Hebrew Bible’s most haunting scenes: King Saul has a woman at Endor conjure the dead prophet Samuel. Its roots in ancient necromancy, and its long interpretive afterlife.

The holy spirit said to inhabit Jesus and inaugurate his mission, later the foundation of the doctrine of the Trinity, set within the wider ancient world of divine spirits and ghosts.
