I’ve watched this video several times today and each time end up with tears in my eyes. The melody is Ode to Joy from Beethoven’s Symphony No. 9 and the words are from the poem Joyful, Joyful We Adore Thee by Henry van Dyke. It’s not a christmas hymn, but it is a beautiful reminder of the joy that surrounds the advent of Christ.
Joyful, joyful, we adore Thee, God of glory, Lord of love;
Hearts unfold like flowers before Thee, opening to the sun above.
Melt the clouds of sin and sadness; drive the dark of doubt away;
Giver of immortal gladness, fill us with the light of day!
All Thy works with joy surround Thee, earth and heaven reflect Thy rays,
Stars and angels sing around Thee, center of unbroken praise.
Field and forest, vale and mountain, flowery meadow, flashing sea,
Singing bird and flowing fountain call us to rejoice in Thee.
Thou art giving and forgiving, ever blessing, ever blessed,
Wellspring of the joy of living, ocean depth of happy rest!
Thou our Father, Christ our Brother, all who live in love are Thine;
Teach us how to love each other, lift us to the joy divine.
Mortals, join the happy chorus, which the morning stars began;
Father love is reigning o’er us, brother love binds the Holy Trinity
Ever singing, march we onward, victors in the midst of strife,
Joyful music leads us Sunward in the triumph song of life.
—Henry van Dyke
