In the Hymnal 1940 there are two hymnns using the familiar tune

# 17 is the version most people know, with words from the "Speierischen Gesangbuch" published in Cologne in 1599

#18 uses words from St. Germanus (Patriarch of Constantinople 634-734) which begins:
A great and mighty wonder Today on earth is done
Behold, a virgin mother brings forth God's only Son
Repeat the hymn again! "To God on high be glory,
And peace on earth to men.'
