84. By tradition going back to early Christian times, the divine office is devised so that the whole course of the day and night is made holy by the praises of God. Therefore, when this wonderful song of praise is rightly performed by priests and others who are deputed for this purpose by the Church's ordinance, or by the faithful praying together with the priest in the approved form, then it is truly the voice of the bride addressed to her bridegroom; It is the very prayer which Christ Himself, together with His body, addresses to the Father.

85. Hence all who render this service are not only fulfilling a duty of the Church, but also are sharing in the greatest honor of Christ's spouse, for by offering these praises to God they are standing before God's throne in the name of the Church their Mother.

90. The divine office, because it is the public prayer of the Church, is a source of piety, and nourishment for personal prayer. And therefore priests and all others who take part in the divine office are earnestly exhorted in the Lord to attune their minds to their voices when praying it. The better to achieve this, let them take steps to improve their understanding of the liturgy and of the bible, especially of the psalms.

- Excerpts from Vatican 2, Sacrosanctum Concilium

Soul of my Savior, sanctify my breast;
Body of Christ, be thou my saving guest;
Blood of my Savior, bathe me in thy tide;
Wash me in water flowing from his side.

Strength and protection may thy Passion be;
O blessed Jesus, hear and answer me;
Deep in thy wounds, Lord, hide and shelter me;
So shall I never, never part from thee.

Guard and defend me from the foe malign;
In death’s drear moments make me only thine;
Call me and bid me come to thee on high;
Where I may praise thee with thy saints for aye.
