grant that we who are are bathed
in the new light of your incarnate Word
may reflect the faith
that shines in our hearts
in all we do;
through your Son,
Jesus Christ our Lord,
who lives and reigns with you and the Holy Spirit,
one God, now and forever.

Original in Latin:
Da, quaesumus, omnipotens Deus, ut dum nova incarnati Verbi tui luce perfundimur, hoc in nostro resplendeat opere, quod per fidem fulget in mente.
