Was Joseph Jesus\u2019 biological father or adoptive father? Joseph is a major figure in the nativity stories in Matthew and Luke<\/a>. Along with Mary, he is depicted at Jesus\u2019 birth in this 16th-century painting by Lorenzo Lotto. Photo: Courtesy National Gallery of Art, Washington, DC.<\/em><\/p><\/div>\n

Was Joseph Jesus<\/a>\u2019 biological father? If not, who was Jesus\u2019 biological father?<\/p>\n

The annunciation stories in the Gospels of Matthew and Luke recount that Jesus was conceived without the participation of a human male. Ancient views<\/a> on the biology of conception\u2014based on Aristotelian theory\u2014differed from our modern understanding of genetics and biology. For Jesus to have been considered fully human by our modern standards\u2014and not a semi-divine or special being\u2014he would have needed complete human DNA. While Mary would have supplied the X chromosome, who supplied the essential Y chromosome? God? Joseph?<\/p>\n

Andrew Lincoln of the University of Gloucestershire tackles these questions in his article \u201cHow Babies Were Made in Jesus\u2019 Time<\/a>\u201d in the November\/December 2014 issue of BAR<\/strong><\/a>. Starting with the nativity stories in Matthew and Luke, he examines what early Christians thought about conception and explains how views about this subject have changed over time.<\/p>\n

Who was Jesus\u2019 biological father? As modern readers, we might wonder how the product of a virginal conception could truly be human\u2014since the Y chromosome did not come from a human father. Andrew Lincoln explains that this issue would not have been troubling to an ancient audience or to the writers of the nativity stories in Matthew and Luke:<\/p>\n

Their understanding of conception, shaped by a patriarchal culture, would have been some variation of the dominant Aristotelian theory. On this view, the male semen provides the formative principle for life. The female menstrual blood supplies the matter for the fetus, and the womb the medium for the semen\u2019s nurture. The man\u2019s seed transmits his logos<\/em> (rational cause) and pneuma<\/em> (vital heat\/animating spirit), for which the woman\u2019s body is the receptacle. In this way the male functions as the active, efficient cause of reproduction, and the female functions as the provider of the matter to which the male seed gives definition. In short, the bodily substance necessary for a human fetus comes from the mother, while the life force originates with the father.<\/p><\/blockquote>\n

Those who heard the nativity stories in Matthew and Luke would have considered Jesus to be fully human since his mother supplied all of his bodily substance. Lincoln clarifies: \u201cIn terms of ancient biology, even without a human father, Jesus would have been seen as fully human. His mother, Mary, provided his human substance, and in this case God, through the agency of the divine Spirit, supplied the animating principle instead of a human father.\u201d<\/p>\n\n\n\t\t
