In which book of the Bible is the birth of Jesus celebrated by the shepherds?

The birth of Jesus is celebrated by the shepherds in the Gospel of Luke. This account is found in Luke 2:8-20, where shepherds in the fields receive the announcement of Jesus' birth from an angel. They are instructed to go to Bethlehem and find the newborn Savior wrapped in cloths and lying in a manger. This narrative emphasizes the humility of Jesus' birth and highlights the theme of God's message of salvation being revealed to the lowly and marginalized, represented by the shepherds.

In contrast, the other Gospels present different perspectives on Jesus' birth. The Gospel of Mark begins with Jesus' adult ministry and does not include a nativity story. The Gospel of Matthew contains the account of the Magi visiting Jesus but does not mention the shepherds. The Gospel of John focuses on the theological implications of Christ's coming, introducing Him as the Word made flesh, without detailing His birth in the same narrative way. Hence, the Gospel of Luke is the prominent source for the shepherds' celebration of Jesus’ birth.
