The 13th-century Cistercian monk and chronicler Peter of Vaux de Cernay claimed it was part of Catharist belief that the earthly Jesus Christ had a relationship with Mary Magdalene, described as his concubine.
Early Mormon leaders Jedediah M. Grant and Orson Hyde stated it was part of their religious belief that Jesus Christ was polygamous, quoting an apocryphal passage attributed to the 2nd-century Greek philosopher Celsus: "The grand reason why the gentiles and philosophers of his school persecuted Jesus Christ was because he had so many wives. There were Elizabeth and Mary and a host of others that followed him".
The French 19th century socialist politician, Louis Martin, in his 1886 book Les Evangiles sans Dieu described the historical Jesus as a turned atheist, who had married Mary Magdalene, and that both had travelled to the South of France, where they had a son.
The Jesus bloodline hypothesis which held that the historical Jesus had married Mary Magdalene and fathered a child with her was brought to the attention of the general public again in the 20th century by Donovan Joyce in his 1973 book The Jesus Scroll. In his 1977 book Jesus died in Kashmir: Jesus, Moses and the ten lost tribes of Israel, Andreas Faber-Kaiser explored the legend that Jesus met, married and had several children with a Kashmiri woman. The author also interviewed the late Basharat Saleem who claimed to be a Kashmiri descendant of Jesus. Michael Baigent, Richard Leigh, and Henry Lincoln developed and popularized the hypothesis that a bloodline from Jesus and Mary Magdalene eventually became the Merovingian dynasty in their 1982 book The Holy Blood and the Holy Grail,in which they asserted: The symbolic significance of Jesus is that he is God exposed to the spectrum of human experience -- exposed to the first-hand knowledge of what being a man entails. But could God, incarnate as Jesus, truly claim to be a man, to encompass the spectrum of human experience, without coming to know two of the most basic, most elemental facets of the human condition? Could God claim to know the totality of human existence without confronting two such essential aspects of humanity as sexuality and paternity? We do not think so. In fact, we do not think the Incarnation truly symbolises what it is intended to symbolise unless Jesus were married and sired children. The Jesus of the Gospels, and of established Christianity, is ultimately incomplete -- a God whose incarnation as man is only partial. The Jesus who emerged from our research enjoys, in our opinion, a much more valid claim to what Christianity would have him be.
