O Come, Redeemer of the earth,
and manifest thy virgin-birth.
Let every age in wonder fall:
such birth befits the God of all.
Begotten of no human will
but of the Spirit, Thou art still
the Word of God in flesh arrayed,
the promised fruit to man displayed.
The Virgin’s womb that burden gained,
its virgin honor still unstained.
The banners there of virtue glow;
God in his temple dwells below.
Proceeding from His chamber free
that royal home of purity
a giant in twofold substance one,
rejoicing now His course to run.
O equal to the Father, Thou!
gird on Thy fleshly mantle now;
the weakness of our mortal state
with deathless might invigorate.
Thy cradle here shall glitter bright,
and darkness breathe a newer light
where endless faith shall shine serene
and twilight never intervene. – St. Ambrose
All praise, eternal Son, to Thee,
whose advent sets Thy people free,
whom, with the Father, we adore,
and Holy Ghost, for evermore. Amen.
