The Jesus bloodline refers to the proposition that a lineal sequence of descendants of the historical Jesus has persisted to the present time. The claims frequently depict Jesus as married, often to Mary Magdalene, and as having descendants living in Europe, especially France but also the UK. Differing and contradictory Jesus bloodline scenarios, as well as more limited claims that Jesus married and had children, have been proposed in numerous modern books. Some such claims have suggested that Jesus survived the crucifixion and went to another location such as France, India or Japan. Though absent from the Gospels or historical records, the concept of Jesus having blood descendants has gained a presence in the public imagination, as seen with Dan Brown's best-selling novel and movie The Da Vinci Code that used the premise for its plot, it is generally dismissed by the scholarly community. These claimed Jesus' bloodlines are distinct from the biblical genealogy of Jesus and from the documented 'brothers' and other kin of Jesus, known as the Desposyni. Jesus as husband and father Historical precursors Ideas that Jesus Christ might have been married have a long history in Christian theology, though the historical record says nothing on the subject. Bart D. Ehrman, chair of the Department of Religious Studies at the University of North Carolina, commented that, although there are some historical scholars who claim that it is likely that Jesus was married, the vast majority of New Testament and early Christianity scholars find such a claim to be historically unreliable. Much of the bloodline literature has a more specific focus, on a claimed marriage between Jesus and Mary Magdalene. There are indications in Gnosticism of the belief that Jesus and Mary Magdalene shared an amorous, and not just a religious relationship. The Gnostic Gospel of Philip tells that Jesus "kissed her often" and refers to Mary as his "companion". Several sources from the 13th-century claim that an aspect of Catharist theology was the belief that the earthly Jesus had a familial relationship with Mary Magdalene. An Exposure of the Albigensian and Waldensian Heresies, dated to before 1213 and usually attributed to Ermengaud of Béziers, a former Waldensian seeking reconciliation with the mainstream Catholic Church, would describe Cathar heretical beliefs including the claim that they taught "in the secret meetings that Mary Magdalen was the wife of Christ". A second work, untitled and anonymous, repeats Ermengaud's claim. The
