Settings of the Gloria in Excelsis find their origin in the song of the heavenly host to the shepherds near Bethlehem (Luke 2).  Today's service focuses on the meaning and importance of the Gloria in Excelsis Christians across the world use in their liturgies.  It is a heavenly song that the angels sing, one similar to the songs of heaven found throughout Revelation; for example: "Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing"  (Revelation 5:12).  That evening some two thousand years ago, heaven met earth as the Son of God was born of the Virgin Mary, sent forth from His Father's throne to do the work of salvation. What a blessing it is to join Christians around the world who have for centuries before us sung this song of praise to our God.
