O Sanctissima

O thou bhappy,
O thou holy,
Glorious peace bringing Christmastime.
Angel throngs to meet thee;
On thy birth we greet thee;
All hail Jesus , our Savior King.

Day of holiness,
Peace and happiness,
Joyful, glorios Christmas Day.
Angels tell the story
Of this day of glory;
Praise Christ our Savior born this Christmas Day.

I have these words but they are not exactly as I remember from years ago. The last line I remember as ' Praise Him O praise Him on ev'ry side.'
