Google Translation of Verse 1:

Christmas, Christmas, glorious Christmas, glory over white forests,
Christmas, Chistmas, Brilliant chrismas, Shine over white Forests
Heaven crowns with sparkling light,
the Crown of the heavens with brilliant lights
Gleaming arcs in all God's house,
Glowing archers in all god's houses
Hymn, which is sung from time to time,
Anthem, That is sung from time to time (from age to age)
Eternal longing for light and peace!
Eternal longing for light and peace
Christmas, Christmas, glorious Christmas, splendor over white woods!


Google translation of Verse 2:
Come, come, designed Christmas! Lower your white wings
Over the  blood and alarm of battles,
Over all sighing (groaning) from the human breast,
Over the generations that go to their rest,
Over the young [dagande], stay!•
Come, come, heraldling Christmas! Lower your white wings.


•I'll go with thomas's translation, above, for now.
