If you haven’t heard the music, it may be because you’re not listening. What music? The song first sung over the fields of Bethlehem as angels sang, “Glory to God in the highest, and on earth peace to men on whom his favor rests” (Luke 2:14). The traditional French carol put it, “Angels we have heard on high/ Sweetly singing o’er the plains:/ And the mountains in reply, Echoing their joyous strains./ Gloria in excelsis Deo! Gloria in excelsis Deo.”
