The Cold-Case Christianity Podcast

In this episode, J. Warner Wallace takes you into the forensic details of the Bible's sacrificial system to examine a stunning claim: when John the Baptist called Jesus "the Lamb of God who takes away the sin of the world," he was doing something that flatly breaks the Old Testament lamb pattern.
Using the same cold-case, investigative approach he applied for years as a detective, J. Warner shows that the mismatch between the Old Testament lamb pattern and Jesus' sacrifice is not a problem to explain away—it's a powerful evidential clue that Jesus is the God-man, whose once-for-all sacrifice has infinite worth.
If you've ever wondered how the sacrificial system really worked, whether penal substitution is biblically grounded, or why Jesus must be God for the atonement to make sense, this episode will help you see the Lamb of God with fresh eyes.

If Mark really preserves Peter's eyewitness testimony, what does that mean for the other Gospels—and for skeptical claims that the New Testament is late, legendary, and contradictory? In this follow‑up episode, we build on the case from Part 1 and argue that Mark is not only rooted in Peter's preaching, but is also likely the earliest written Gospel that Matthew and Luke used as a framework.
You'll hear why Mark's short, urgent, "rough" style points to an early source, how Matthew and Luke expand and smooth Mark's material, and what editorial patterns suggest about who was copying whom. We'll also explore Mark's heavy emphasis on suffering, persecution, and costly discipleship, and show why that matters when responding to prosperity teaching and "legend" objections.
Finally, we'll connect all of this to practical evangelism: how understanding Mark as Peter's first‑hand case file can help you answer skeptics, strengthen your confidence in Scripture, and share the story of Jesus as real history rather than religious rumor.

Was the Gospel of Mark built on real eyewitness testimony—or is it just another religious legend? In this episode, cold‑case detective and Christian apologist J. Warner Wallace (you) walks through the historical and forensic evidence that Mark's Gospel is rooted in the firsthand experiences of the apostle Peter. You'll discover why early Christian writers called Mark "Peter's interpreter," how Mark's rough Greek, Aramaic quotes, and Roman details fit a live translation of Peter's preaching, and why Peter's fingerprints are visible all over the narrative.
We'll examine ancient sources, internal stylistic clues, and the structure of Mark itself, arguing that this is not a distant, polished myth but a raw, early case report from someone in Jesus' inner circle. If you've ever wondered whether you can really trust the Gospels—or if skeptics in your life have raised those questions—this episode will give you solid reasons to treat Mark as powerful eyewitness evidence.

In this episode, cold-case detective and Christian apologist J. Warner Wallace reopens "the Judas file" and asks a blunt question: Was Judas ever truly saved, or was he an unsaved insider from the start? Drawing on a detective's methodology, J. Warner walks verse by verse through every major Judas passage, examines Judass remorse in Matthew 27, and weighs historic voices—from the Church Fathers to the Reformers—before offering a cautious but clear verdict. Along the way, he shows how Judas became a trusted ministry insider, a treasurer, and a preacher, yet still serves as a chilling warning that you can be close to Jesus, busy in ministry, and never actually belong to Him. This episode is designed to help believers, leaders, and skeptics think more carefully about salvation, apostasy, secret sin, and the danger of mere proximity to the truth.

How do you investigate the "missing centuries" of the Shroud of Turin like a real cold-case detective? In this third episode on the Shroud of Turin, J. Warner Wallace walks through the most popular claims about pre‑Turin relics—sudariums, veils, and rival "shrouds"—and explains why none of them close the chain‑of‑custody gap needed to treat the Turin cloth as first‑century evidence for Jesus.
