The 'Great O's' of Advent are seven invocations of the different names of Christ, looking towards his coming into the world under different titles. Each one, addressing Christ, begins 'O..!'
They are used as antiphons (opening and closing threads of song) for the Magnificat which is how we offer them, during Evening Prayer, from Sunday 17 to Saturday 23 December.
attingens a fine usque ad finem,
fortiter suaviterque disponens omnia:
veni ad docendum nos viam prudentiae.
reaching from one end to the other,
mightily and sweetly ordering all things:
Come and teach us the way of prudence.
qui Moysi in igne flammae rubi apparuisti,
et ei in Sina legem dedisti:
veni ad redimendum nos in brachio extento.
who appeared to Moses in the fire of the burning bush
and gave him the law on Sinai:
Come and redeem us with an outstretched arm.
super quem continebunt reges os suum,
quem Gentes deprecabuntur:
veni ad liberandum nos, jam noli tardare.
before you kings will shut their mouths,
to you the nations will make their prayer:
Come and deliver us, and delay no longer.
qui aperis, et nemo claudit;
claudis, et nemo aperit:
veni, et educ vinctum de domo carceris,
sedentem in tenebris, et umbra mortis.
you open and no one can shut;
you shut and no one can open:
Come and lead the prisoners from the prison house,
those who dwell in darkness and the shadow of death.
splendor lucis aeternae, et sol justitiae:
veni, et illumina sedentes in tenebris, et umbra mortis.
splendour of light eternal and sun of righteousness:
Come and enlighten those who dwell in darkness and the shadow of death.
lapisque angularis, qui facis utraque unum:
veni, et salva hominem,
quem de limo formasti.
the cornerstone making both one:
Come and save the human race,
which you fashioned from clay.
exspectatio Gentium, et Salvator earum:
veni ad salvandum nos, Domine, Deus noster.
the hope of the nations and their Saviour:
Come and save us, O Lord our God.
