When did the early Christians begin to seek the intercession of particularly holy people, such as the martyrs? Was this something they copied from Greco-Roman society? In the latest episode of Controversies in Church History, we take a look at the origins of the cult of the saints. In it, I discuss when and how the early Christians began to venerate Christian martyrs, and the evidence of this practice. I address the similarities and differences between the veneration of the saints and Greco-Roman religion, and why veneration of saints marked a radical departure from other religions in the ancient world.
