In this remote Science Salon (recorded on February 19, 2018), Dr. Shermer converses with the great bible scholar and historian Dr. Bart D. Ehrman, the Distinguished Professor of Religious Studies at the University of North Carolina at Chapel Hill.

Dr. Ehrman is a leading authority on the New Testament and the history of early Christianity and the author of 8 Teaching Company courses and a number of New York Times bestselling books, including Misquoting Jesus and How Jesus Became God. In his new book, The Triumph of Christianity: How a Forbidden Religion Swept the World, Dr. Ehrman explores how a tiny sect of just 20 people at the time of Jesus' crucifixion in 30 CE became 25 to 35 million Christians by 400 CE. Imagine if the couple of dozen Branch Davidians living near Waco, Texas in early 1990s, instead of being incinerated by Federal agents in a botched stand-off, went on to convert two billion people around the world to their religion. That is what early Christians did. How did they do that?

Shermer and Ehrman also discuss the modern atheism movement, how Jesus became a Republican in the second half of the 20th century, the intractable (for Christians) problem of evil, the problem of identity for Jesus (how could he be both man and God?), what pre-Christian pagans believed about the gods, what early Christians had to offer pagans that other religions didn't, how religions invented the afterlife and what people believed before the rise of Christianity about what happens after you die, and other fascinating topics.
