Liturgical Colour : Green or White (Dedication of the Basilica of St. Mary Major)

Psalm 50 : 3-4, 5-6a, 6bc-7, 12-13

Have mercy on me, o God, in Your love. In Your great compassion blot out my sin. Wash me thoroughly of my guilt; cleanse me of evil.

For I acknowledge my wrongdoings and have my sins ever in mind. Against You alone, have I sinned.

What is evil in Your sight, I have done. You are right when You pass sentence; and blameless in Your judgement. For I have been guilt-ridden from birth; a sinner from my mother’s womb.

Create in me, o God, a pure heart; give me a new and steadfast spirit. Do not cast me out of Your presence nor take Your Holy Spirit from me.

Judith 13 : 18-19

My daughter, may the Most High God bless you more than all women on earth. And blessed be the Lord God, the Creator of heaven and earth, Who has led you to behead the leader of our enemies.

Never will people forget the confidence you have shown; they will always remember the power of God.
