Introductory Prayer to the Divine Office
At the beginning of the Office: Lord God, I offer this Divine Office to you, together with the adoration and praise of the angels and saints in heaven, as well as that of all the priests of your Church and all other consecrated souls. I present to you, holy Father, through the Immaculate Heart of Mary, this chorus of prayer, made holy in the Heart of Jesus and made one with His most holy prayer. May all the words of this prayer be acts of pure love, adoration, thanksgiving, satisfaction, trust, and surrender to your holy Will. Let this prayer be for my weak self a spiritual communion, an act of humility, and of perfect self-denial; and may it be a sacrifice of praise and glory to you, O Blessed Trinity. Amen.
Thereafter, at the various Hours and at Vespers: Eternal Father, through the Heart of Jesus, your Son, in union with the Immaculate Heart of Mary, I humbly offer you this holy Office as a sign of love and as a means of reparation.
