The Nativity of Jesus or Birth of Jesus is described in the gospels of Luke and Matthew. In Christian theology the nativity marks the incarnation of Jesus as the second Adam, in fulfillment of the divine will of God, undoing the damage caused by the fall of the first man, Adam. The nativity plays a major role in the Christian liturgical year. The date of birth for Jesus of Nazareth is not stated in the gospels or in any secular text, but a majority of scholars assume a date of birth between 6 BC and 4 BC. Mary, the mother of Jesus, was betrothed to Joseph, but was found to be pregnant through the Holy Spirit. The theological significance of the Nativity of Jesus has been a key element in Christian teachings, from the early Church Father to 20th century theologians.
