Where Did Original Sin Come From?

Most Christians grow up believing that everyone is born a sinner, that when Adam and Eve ate the fruit, humanity inherited a broken nature and a guilt we can't escape. It's one of the most influential ideas in Western Christianity. But it isn't in Genesis, Jesus never taught it, and it didn't take its familiar form until four centuries after him. Bart joins host Megan Lewis to trace where original sin actually came from: what the Garden of Eden story says and doesn't say, what Paul meant when he wrote that sin came into the world through one man, and how Augustine turned that line into a doctrine about every human being from the moment of conception. Along the way, why Eastern Orthodox Christians never fully accepted it, and what changes when you realize this belief has a history.
