O come, all ye faithful,
Joyful and triumphant,
O come ye, O come ye to Bethlehem.
Come and behold Him,
Born the King of Angels!
O come, let us adore Him,
O come, let us adore Him,
O come, let us adore Him,
Christ the Lord.

Yea, Lord, we greet Thee,
Born this happy morning;
Jesus, to Thee be the glory giv'n;
Word of the Father,
Now in the flesh appearing,
O come, let us adore Him,
O come, let us adore Him,
O come, let us adore Him,
Christ the Lord.
