The Gospel of Luke tells of the origins, birth, ministry, death, resurrection, and ascension of Jesus Christ. Together with the Acts of the Apostles, it makes up a two-volume work which scholars call Luke–Acts, accounting for 27.5% of the New Testament. The combined work divides the history of first-century Christianity into three stages, with the gospel making up the first two of these – the life of Jesus the Messiah from his birth to the beginning of his mission in the meeting with John the Baptist, followed by his ministry with events such as the Sermon on the Plain and its Beatitudes, and his Passion, death, and resurrection.

The nativity of Jesus, nativity of Christ, birth of Jesus or birth of Christ is documented in the biblical gospels of Luke and Matthew. The two accounts agree that Jesus was born in Bethlehem, Judaea, that his mother, Mary, was engaged to a man named Joseph, who was descended from King David and was not his biological father, and that his birth was caused by divine intervention. Some scholars do not see the two canonical gospel nativity stories as historically factual since they present clashing accounts and irreconcilable genealogies. The secular history of the time does not synchronize with the narratives of the birth and early childhood of Jesus in the two gospels. Some view the question of historicity as secondary, given that gospels were primarily written as theological documents rather than chronological timelines.
