It’s almost Easter, which can mean only one thing: it’s time for the blockbuster Bible bestsellers. Last week, Bart Ehrman promoted his new book, How Jesus Became God, on NPR’s Fresh Air. Ehrman advances a common argument: Christian conceptions of Jesus’ identity grew more elaborate with time. His followers first perceived Jesus as a remarkable preacher or prophet, but eventually believers came to regard him as God incarnate. Although I was aware of Ehrman’s book, I missed the publicity blitz.
