In September 2012, Harvard Divinity School professor Karen L. King published a fourth-century Coptic papyrus fragment in which Jesus refers to someone (probably Mary Magdalene) as "My wife" and mentions that "she will be able to be my disciple." The document is a copy of a late second-century manuscript. This link takes you to the HDS press release, which provides a summary of the discovery and access to a draft article that Dr. King will soon publish in Harvard Theological Review.
Dr. King introduced the manuscript in the following video from the Harvard Divinity School:
The Smithsonian Channel made plans with Dr. King to air a special TV program on the manuscript. In this trailer, Dr. King explains why this document is so unique.
However, scholars began to voice concerns about the authenticity of the manuscript, and the Smithsonian Channel pulled the plug. The Harvard Theological Review continued with its plan to publish Dr. King's analysis of the manuscript, but delayed publication until the editors could secure a host of other scholars to help evaluate the authenticity of the piece. Their articles, and those of others, are listed in the bibliography below.
