Luke is indeed the only one to report the detail of the infant Jesus' circumcision, a rite prescribed by God and mentioned in the book of Leviticus 12.3. In accordance with Mosaic law, Joseph and Mary have the child circumcised. Since the operation did not require a journey to Jerusalem, it most probably took place in Bethlehem.
In his Gospel, Luke emphasises Jesus the Messiah's humanity and the importance he attaches to observing Jewish law, an essential component of his account.
Following the angel Gabriel's announcement, Joseph and Mary name the child Jesus, derived from the Hebrew name Yehoshua (Joshua), meaning ‘the is salvation’. The events surrounding his birth clearly confirm that the child is destined for greatness, an idea Mary ponders deeply, aware of the many meanings of these events.
