Angels we have heard on high
Sweetly singing o'er the plains
And the mountains in reply
Echoing their joyous strains

Shepherds, why this jubilee?
Why your joyous strains prolong?
What the glad song's tidings breathe
Which inspire your heavenly song?

Gloria in excelsis Deo
Gloria in excelsis Deo
[ Lyrics from: http://www.lyricsfreak.com/m/mercyme/gloria_20486746.html ]
Come to Bethlehem and see
Christ whose birth the angels sing
Come adore on bended knee
Christ the Lord, the newborn King

See Him in a manger laid
Whom the choirs of angels praise
Mary, Joseph, lend your aid
While our hearts in love we raise

How could Heaven's heart not break
On the day, the day that You came?
Salvation's reason to celebrate
On the day, the day that You came

Gloria, gloria, gloria
