This article sets a precedent that the authorship of the Fourth Gospel (Gospel of John) in the New Testament should be attributed to Mary Magdalene. To my knowledge, no previous publication has provided evidence to support this hypothesis. Most Bible scholars today claim that the Fourth Gospel was created by an unknown follower of Jesus who is mentioned in the Gospel text as His beloved disciple. This work postulates that in the early tradition of the Fourth Gospel community, the "unknown" now beloved disciple was known as Mary Magdalene. It is further stated that Mary Magdalene is the true founder and protagonist of what has come to be known as the Johannine Community (i.e. Mary Magdalene was one of the original founding apostles and leaders of the early Christian church). I realize that this hypothesis may seem very radical and perhaps unacceptable to you. However, I believe that this is well supported by the facts, and in support of this I respectfully offer the following. Evidence supporting this thesis includes some Gnostic Christian writings from the Nag Hammadi library and internal evidence from the text of the Fourth Gospel itself. This article also draws heavily on the study of the Johannine Community by Raymond E. Brown (America's foremost Catholic biblical scholar). Ramon C. Jusino
