The Gospel of Jesus’ wife was a forgery by a certain Walter Fritz. Fritz managed to convince a historian of early Christianity at Harvard, Karen L. King, the a fragment of papyrus, written in the ancient language of Coptic, contained a legend about Jesus having married. King presented it at a conference in Rome in September 2012, and the story quickly spread through the world’s press. It was exposed as a hoax by an investigative journalist in July 2016.
