Harvard researcher Karen King today unveiled an ancient papyrus fragment with the phrase, “Jesus said to them, ‘My wife.’” The text also mentions “Mary,” arguably a reference to Mary Magdalene. The announcement at a religious studies conference in Rome is sure to send shock waves through the Christian world. The Smithsonian Channel will premiere a special documentary about the discovery on September 30 at 8 p.m. ET. And Smithsonian magazine reporter Ariel Sabar has been covering the story behind the scenes for weeks, tracing King’s steps from when a suspicious e-mail hit her in-box to the nerve-racking moment when she thought the entire presentation would fall apart.
