THE SIGN OF THE CROSS
Make the Sign of the Cross, ✠ saying
IN the name of the Father, and of the Son, and of the Holy Ghost. Amen.
This sacred sign may be regarded as a compendium of all the mysteries of our Faith, as a homage rendered to the three Persons of the adorable Trinity, as an act of gratitude for all that the Godhead — the Father, the Son, and the Holy Spirit — has condescended to do in favor of man.
His Holiness, Pope Pius IX, by a brief, July 28, 1863, granted to all the faithful, every time that, with at least contrite heart, they shall make the sign of the cross, invoking at the same time the blessed Trinity with the words: In the name of the Father, and of the Son, and of the Holy Ghost, an indulgence of 50 days.

HOLY, holy, holy, Lord God of hosts! the earth is full of Thy glory. Glory be to the Father, glory be to the Son, glory be to the Holy Ghost.

Prayer for Sunday to the Blessed Trinity
O BLESSED Trinity, Father, Son, and Holy Ghost, the source and fountain of all good, I most firmly believe in You, I most humbly adore You, and thank You, with a grateful heart for all the blessings and benefits I have received from Your infinite goodness. I most fervently consecrate and offer to You an unreserved sacrifice of my whole being. O my God, Who hast a right to every day, hour, and moment of my existence, accept the thoughts, words, and actions of this day, which I offer Thee in testimony of my sincere desire to satisfy my obligation of keeping it holy and as the first-fruits of the week; mercifully assist me to spend it in such a manner as may draw down Thy blessing. Increase in my soul the heavenly virtues of faith, hope, and charity, which I received at Baptism, and teach me to make faith the rule of my conduct, that thereby it may avail me to life everlasting. Eternal Father, take possession of my memory; efface from it all ​images of vanity, and engrave therein the recollection of Thy adorable presence. Eternal Son, enlighten my understanding, and conduct me in the path of salvation by the light of faith. Holy Spirit, sanctify my will by the most ardent love; render it submissive under the contradictions of this life, and never permit that by attachment to my own ideas or judgment, I should forfeit the blessings of peace offered to men of good will and obedient minds. Holy, adorable, undivided Trinity, by Whose power, mercy, and providence I was created, redeemed, regenerated, and preserved to this moment, receive the oblation of my whole being, and take me out of the world rather than permit me to efface Your sacred image in my soul by mortal sin. I adore You, O Holy Trinity, I worship You, I most humbly give You thanks for having revealed to man this glorious, this incomprehensible mystery, and for granting to those who persevere until death in the faithful profession of it, the reward of beholding and enjoying in heaven what we now believe and adore upon earth, one God in three Persons, the Father, the Son, and the Holy Ghost. Amen.
ASPIRATION
GLORY be to the Father, and to the Son, and to the Holy Ghost; as it was in the beginning, is now, and ever shall be, world without end. Amen.
Indulgence of loo days, thrice a day, for saying morning, noon, and evening, Gloria Patri thrice, in thanksgiving to the Most Holy Trinity for the graces and privileges granted to most holy Mary, especially in her glorious Assumption into heaven. — Pius VII, July 11, 1815.
