More than three-quarters of North Americans believe in angels. But what are angels, and where do they come from? In this episode of Decoding Christianity, host Christy Kenneally considers the many ways in which artists have portrayed angels over the centuries. He ventures into the catacombs of Rome to find one of the earliest depictions of a Christian angel, learns how angels got their wings, and ponders the dark side of angels. Finally, he takes a look at the present-day angel industry, traveling to Reno, Nevada to meet a woman who claims to be a channel for the Archangel Michael.
