"And suddenly there was with the angel a multitude of the heavenly host praising God, and saying, 'Glory to God in the highest, and on earth peace, good will toward men'" (Luke 2:13-14). Those words are transposed into the mouth of the people in the Mass, a jubilant reminder of the wonder of the Incarnation and the beauty of the Trinity. Part 2 of our series on the Ordinary of the Mass looks at how the form of the Gloria communicates its message, as well as ways in which composers simplify text-setting for longer texts.
