In this episode of The Backstory on the Shroud of Turin, Guy R. Powell welcomes Dale Glover of Real Seekers. Rather than conducting a traditional interview, Guy and Dale revisit major skeptical challenges surrounding the Shroud of Turin.

Their discussion grows from Dale’s earlier debate with cognitive neuroscientist James Fodor. Dale examines whether known medieval methods can account for the Shroud’s unusual characteristics.

Topics include:

• Historical evidence that may predate the fourteenth century
• The Shroud’s unusual 3D image information
• The VP-8 Image Analyzer and topographical information
• Bas-relief theories and wraparound distortion
• Problems aligning frontal and dorsal images
• The absence of a known medieval artistic technique
• Dale’s “minimal relevant features” approach
• Superficiality, image uniformity, and vertical collimation
• Questions surrounding the 1988 radiocarbon dating
• Long fingers and apparent differences in arm length
• Rigor mortis and the body’s position
• Burial spices and possible cloth positioning
• Philosophical criteria for identifying a miracle
• The possible motivation behind a medieval forgery

Dale argues that proposed natural methods must explain the complete set of image characteristics. Reproducing only one or two unusual features is not enough under his approach.

The conversation eventually reaches the central Christian question. Could the Shroud represent a physical consequence connected with the Resurrection of Jesus Christ? Guy and Dale explore that possibility while acknowledging ongoing disagreement surrounding the cloth.

For believers, the discussion offers another way to examine Christianity’s central claim. For skeptics, it presents specific historical, scientific, and philosophical arguments to investigate. The episode also complements Guy Powell’s The Only Witness: A History of the Shroud of Turin.

What really happened during the trial of Jesus Christ? Could the Shroud of Turin provide important clues?

In this episode of The Backstory on the Shroud of Turin, Guy R. Powell welcomes Christian scholar and Psalm Log founder Preston Zeller for an in-depth discussion about history, biblical scholarship, and scientific research surrounding the Shroud.

• Carbon dating and modern testing methods
• DNA and historical research
• The mystery of the Shroud's image formation
• The suffering of Jesus Christ
• Jewish legal procedures during the trial
• Why many scholars believe the trial violated established law

Can physical evidence strengthen belief in the Resurrection of Jesus Christ?

In this episode of The Backstory on the Shroud of Turin, Guy Powell welcomes longtime Shroud researcher Lee Sweeney, Director of the Shroud Center at the Santiago Retreat Center in California. Together they explore why the Shroud of Turin continues to inspire believers, challenge skeptics, and engage young people searching for authentic answers.

Lee shares how more than two decades of teaching have shaped his approach to presenting the Shroud. Rather than asking people to accept faith without evidence, he introduces them to the historical, scientific, and biblical facts surrounding one of Christianity's most studied artifacts.

The conversation explores:

• Why today's generation wants tangible evidence.
• How the Shroud opens conversations about faith.
• The relationship between science and Christianity.
• Research into the mysterious image formation.
• Why many researchers believe the image was produced by light.
• How the Shroud helps people understand the Passion and Resurrection of Jesus Christ.

• Why faith and science complement one another.

Lee also discusses his experience presenting the Shroud to thousands of students and church groups. He explains how many begin with doubts but leave asking deeper spiritual questions.

Whether you are exploring Christianity, researching the Shroud of Turin, or reading The Only Witness, this episode offers thoughtful insights into history, science, and faith.

Can the Bible answer the questions that many Christians ask about the Shroud of Turin? In this episode of The Backstory on the Shroud of Turin, Guy Powell is joined by theologian and Christian apologist Tom Dallis for an in-depth discussion of twelve biblical objections that are frequently raised against the Shroud. Rather than dismissing these questions, Tom examines each one through the lens of Scripture, history, and first-century Jewish culture, offering thoughtful explanations that encourage listeners to explore the biblical evidence for themselves.

The conversation covers the Gospel accounts of the burial of Jesus Christ, the meaning of the Greek words used to describe His burial cloths, Isaiah's prophecies, Jewish burial customs, Joseph of Arimathea's role, and the relationship between the Day of Atonement and the Resurrection. Tom also explains why understanding the historical and cultural context of Scripture is essential when evaluating claims about the Shroud. One of the episode's most compelling sections explores how the High Priest's linen garments described in the Old Testament may provide a remarkable theological parallel to the burial cloths found in Christ's empty tomb.

Whether you are approaching the Shroud of Turin from the perspective of faith, biblical scholarship, or historical curiosity, this episode offers an engaging and balanced examination of some of the most frequently misunderstood passages in Scripture. It also expands on many of the themes found in Guy Powell's book, The Only Witness: A History of the Shroud of Turin, providing listeners with a deeper appreciation of how theology, history, and the Gospel accounts intersect.

In this episode of The Backstory on the Shroud of Turin, host Guy Powell interviews Judge David Belz, a former trial lawyer and superior court judge.

Belz brings a legal perspective to one of history’s most debated artifacts. He explains how courtroom evidence standards can be applied to the Shroud of Turin.

He breaks down direct, circumstantial, and corroborating evidence. He argues that corroborating evidence is key to understanding complex truth claims.

Instead of relying on a single scientific test, Belz emphasizes the total body of evidence. This includes historical records, forensic findings, and biblical references to Jesus Christ.

He discusses STURP findings and limitations of isolated interpretations. He also addresses carbon dating controversy and scientific disagreement.

Belz suggests that when all evidence is combined, the case becomes stronger. He frames the discussion around legal reasoning rather than emotional belief.

The conversation explores themes connected to the Resurrection and The Only Witness narrative. It challenges listeners to evaluate evidence like jurors in a courtroom.Whether believer or skeptic, this episode invites deeper reflection on truth

In this episode of The Backstory on the Shroud of Turin, Guy Powell interviews theological writer and researcher Daniel Clausen.

Daniel explores why the forgery theory struggles to explain the full scientific and philosophical evidence surrounding the Shroud. The conversation examines STURP findings, image formation mysteries, 3D encoding, DNA evidence, and the ongoing carbon dating debate.

Topics include:

• Why the forgery hypothesis carries its own burden of proof

• The absence of paint, dyes, and scorch marks

• Why modern science cannot replicate the Shroud image

• The “forger of the gaps” argument

• DNA evidence connected to Middle Eastern origins

• Challenges to the 1988 carbon dating results

David shares how his experience as a trial lawyer and judge shaped his approach to the Shroud of Turin. He explains how legal principles such as circumstantial evidence, corroboration, and “clear and convincing evidence” can be applied to the debate surrounding the cloth.

The discussion explores:

• Confirmation bias and skepticism
• The relationship between faith and evidence
• Bilirubin findings in the bloodstains
• Scientific testing of the Shroud
• The legal concept of cumulative evidence
• How the Shroud aligns with the Gospel accounts
