you are the Light in our darkness,
Creator of all of the elements,
Forgiver of sins.
Your mercy is great
toward those who seek you
with all their heart.
O Lord, we hear your mercy in the morning,
blot out our secret sins;
through Jesus Christ our Lord,
who lives and reigns with you and the Holy Spirit,
one God, now and forever.

Tu es, Domine, illuminator caliginum, conditorque elementorum, remissor criminum, misericordia tua, Domine, magna est super eos qui te toto corde requirunt. Majestas tua, Domine, mane nos exaudiat, et deleat delicta nostra quae tibi non sunt abdita;
