Prayers Before the Office

Before beginning the Office, it is praiseworthy to say the following Prayers.

Open my mouth, O Lord, to bless thy holy Name: cleanse my heart from all vain, evil, and wandering thoughts; enlighten my understanding and kindle my affections, that I may fittingly recite this Office with attention and devotion, and so may be meet to be heard before the presence of thy divine Majesty. Through Christ our Lord.

℟.Amen.

O Lord, in union with that divine intention wherewith thou thyself didst offer thy praises to God while upon the earth, I now recite this Office to thee.

The Our Father and Hail Mary are said secretly.

Our Father, who art in heaven, Hallowed be thy Name. Thy kingdom come. Thy will be done, On earth as it is in heaven. Give us this day our daily bread. And forgive us our trespasses, As we forgive those who trespass against us. And lead us not into temptation, But deliver us from evil. Amen.

Hail, Mary, full of grace, the Lord is with thee. Blessed art thou among women, and blessed is the fruit of thy womb, Jesus. Holy Mary, Mother of God, pray for us sinners, now and in the hour of our death. Amen.

Hymn

Exsultet cælum laudibus

Let heaven’s exultant praises ring,And earth with joy responsive sing:The Apostles’ deeds and high estateThis festal-tide we celebrate.

O ye who, throned in glory dread,Shall judge the living and the dead,True lights, the world illumining,Regard the suppliant prayer we bring.

The gates of heaven, at your command,To all or closed or open stand:May we, at your august decree,Be loosed from our iniquity.

The power, of old to you conveyed,Sickness and health alike obeyed:May ye our ailing souls once moreTo strength and holiness restore;

That Christ, the unerring Judge of doom,When he at time’s last end shall come,May grant us, for his mercy’s sake,Of joys eternal to partake.

All laud to God the Father be;All praise, eternal Son, to thee;All glory, as is ever meet,To God the Holy Paraclete.Amen.

℟.And wisely considered of his doing.

4For he that is mighty hath magnified me: * and holy is his Name.

5And his mercy is on them that fear him * throughout all generations.

6He hath shewed strength with his arm: * he hath scattered the proud in the imagination of their hearts.

7He hath put down the mighty from their seat, * and hath exalted the humble and meek.

8He hath filled the hungry with good things; * and the rich he hath sent empty away.

9He remembering his mercy hath holpen his servant Israel; * as he promised to our forefathers, Abraham and his seed, for ever.

Bow. Glory be to the Father, and to the Son, * and to the Holy Ghost;Stand upright. As it was in the beginning, is now, and ever shall be, * world without end. Amen.
