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!
Sing, choirs of angels, sing in exultation,
sing, all ye citizens of heav’n 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!
Yea, Lord, we greet thee, born this happy morning;
Jesus, to thee be all glory giv’n!
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 the Lord!
Adéste fidéles, laéti, triumphántes,
Veníte, veníte in Béthlehem.
Natum vidéte, Regem angelórum.
Veníte adorémus, Veníte adorémus,
Veníte adorémus, Dóminum.
