Elaine Pagels | What the Nag Hammadi Texts Really Reveal
Elaine Pagels is one of the most influential scholars of early Christianity of the last fifty years. Her groundbreaking work on the Nag Hammadi discoveries transformed how many people understand the origins of Christianity and the remarkable diversity of the early Christian movement.
In this conversation, we explore the discovery of the Nag Hammadi library, the Gospel of Thomas, the Gospel of Mary, and other ancient Christian writings that have fascinated scholars for decades. We discuss whether these texts preserve authentic traditions about Jesus, why they were excluded from the New Testament, and what they reveal about the earliest followers of Christ.
We also examine some of the most controversial passages found in the Gnostic Gospels, whether there was any such thing as orthodoxy before the fourth century, and why these texts continue to provoke debate nearly eighty years after their discovery.
Whether you are interested in biblical history, the historical Jesus, or the origins of Christianity, this conversation offers an accessible and thought-provoking introduction from one of the world's leading scholars in the field.

The Historical Jesus & the Origins of Christianity | Paula Fredriksen
Who was the historical Jesus? Did he really expect the end of the world? How did a small Jewish movement become the religion of the Roman Empire?
In this episode, I speak with renowned historian Paula Fredriksen about the origins of Christianity and her new book, Ancient Christianities: The First Five Hundred Years. We explore the historical Jesus, Paul, the dating of the New Testament, the diversity of the earliest Christian movements, the destruction of the Jerusalem Temple, Constantine, martyrdom, persecution, proto-orthodoxy, celibacy, and the development of Christian doctrine.
We also discuss why the first centuries of Christianity were far more diverse than many people realise, and I finish by asking Paula what she believes is the single most significant discovery in the history of biblical studies.
Whether you're interested in the historical Jesus, early Christianity, biblical scholarship, or church history, this conversation offers a fascinating introduction to one of history's most influential religious movements.

Is the Resurrection Historically Defensible? | Dr Richard C. Miller
I sat down with Dr Richard C. Miller.
Richard is one of the most thought-provoking historians working in New Testament studies today. His research has challenged long-held assumptions about the origins of Christianity, the resurrection of Jesus, and the world in which the Gospels were written.
We begin with some of the biggest questions in biblical scholarship. Who wrote the Gospels? When were they written? What does Richard make of Q, Marcion, and the growing debates over Gospel dating?
From there, we explore Mark's Gospel in depth. Does Jesus actually claim to be God in Mark? Who was Mark writing for, and what was he trying to communicate?
The conversation then turns to the resurrection—a subject Richard has spent years researching. We discuss his book Resurrection and Reception in Early Christianity, the striking parallels between the Gospel resurrection accounts and stories from the Greco-Roman world, figures such as Romulus, and why early Christian writers like Justin Martyr acknowledged these similarities while maintaining that Jesus' resurrection was unique.
Finally, we tackle one of the biggest historical questions of all: can the resurrection be defended as a historical event? Richard offers a perspective that challenges many traditional assumptions and invites us to think more carefully about what historians can—and cannot—say about the origins of Christianity.
Whether you agree with Richard's conclusions or not, this is a fascinating conversation that explores some of the most important debates in New Testament scholarship today.

Why Goodacre rejects the Q hypothesis
The Farrer Hypothesis explained
The relationship between Matthew and Luke

The Historical Jesus Debate| Richard Carrier
In this episode, historian Richard Carrier discusses his latest book, The Obsolete Paradigm of a Historical Jesus, and explains why he believes the traditional scholarly model of Jesus of Nazareth is no longer adequate.
Carrier is one of the most prominent critics of the standard historical Jesus framework. Rather than relying solely on scholarly consensus, he applies Bayesian probability to ancient history in an attempt to measure how strongly the available evidence supports competing hypotheses. His approach has made him one of the most influential—and controversial—figures in contemporary debates about Christian origins.
Topics discussed include:
• What mythicism is and how it differs from traditional historical Jesus scholarship
• Whether the historical Jesus paradigm remains persuasive
• How academic consensus forms and why it can sometimes be misleading
• Bart Ehrman's engagement with Carrier's work
• Bayesian reasoning and historical method
• Paul's letters and the earliest evidence for Jesus
• The "brothers of the Lord" passage
• Alternative explanations for the origins of Christianity
• Professional risk, peer pressure, and scholarly debate within biblical studies
Richard Carrier holds a PhD in Ancient History from Columbia University and is the author of Proving History, On the Historicity of Jesus, and The Obsolete Paradigm of a Historical Jesus.
