“Fear not, for behold I bring you good tidings of great joy, which shall be for all the people” (Lk. 2:10)

A key feature of the duties of angels in the Gospels is to tell God’s people to not be afraid. The angel says it to Zachariah (Lk. 1:13), to Mary (Lk. 2:30), to Joseph (Matt. 1:20), to the Shepherds (as above, Lk. 2:10), and to the women at the tomb on Easter (Matt. 28:5).
