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.

(Alvin:)
Sing, choirs of angels,
Sing in exultation,
Oh, sing, all ye citizens of heaven above;
Glory to God
All glory in the highest;
O come, let us adore him,
O come, let us adore him,
O come, let us adore him, Christ the Lord.

Ye, Lord, we greet thee,
Born this happy morning;
Oh, Jesus, to thee be all glory given;
Word of the Father,
Now in flesh appearing;
O come, let us adore him,
O come, let us adore him,
O come, let us adore him,
Christ, O come, all ye faithful,
Joyful and triumphant!
