Adeste Fideles (O Come, All Ye Faithful)

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:

Chorus: O come, let us adore Him, O come, let us adore Him, O come, let us adore Him, Christ the Lord.

God of God, Light of Light, Lo, he abhors not the Virgin’s womb; Very God, Begotten, not created:

Sing, choirs of angels, Sing in exultation, Sing, all ye citizens of Heaven above! Glory to God In the highest:

Yea, Lord, we greet thee, Born this happy morning; Jesus, to thee be glory given! Word of the Father, Now in flesh appearing!

Adeste fideles læti triumphantes,
Venite, venite in Bethlehem.
Natum videte
Regem angelorum:
Venite adoremus (ter)
Dominum.

Deum de Deo, lumen de lumine
Gestant puellæ viscera.
Deum verum, genitum non factum.
Venite adoremus (ter)
Dominum.

Cantet nunc ‘Io’, chorus angelorum;
Cantet nunc aula cælestium,
Gloria! Soli Deo Gloria!
Venite adoremus (ter)
Dominum.

Ergo qui natus die hodierna.
Jesu, tibi sit gloria,
Patris aeterni Verbum caro factum.
Venite adoremus (ter)
Dominum.

There are additional Latin verses in various sources. For example:

En grege relicto, humiles ad cunas,
Vocati pastores adproperant:
Et nos ovanti gradu festinemus,
Venite adoremus (ter)
Dominum.

Æterni parentis
Splendorem æternum
Velatum sub carne videbimus
Deum infantem
Pannis involutum
Venite adoremus (ter)
Dominum.
