Prayer of St. Pius V for the Extirpation of Heresies & Exaltation of Holy Mother Church
I. O my Lord Jesus Christ crucified, Son of the most Blessed Virgin Mary, open Thy ears, and listen to me as Thou didst listen to Thy eternal Father upon Mount Tabor.
Say then a Credo.
II. O my Lord Jesus Christ crucified, Son of the most Blessed Virgin Mary, open Thine eyes, and look upon me as Thou didst look from the tree of the Cross upon Thy dear Mother sorrowing and afflicted.
III. O my Lord Jesus Christ crucified, Son of the most Blessed Virgin Mary, open Thy blessed mouth, and speak as Thou didst speak to St. John when Thou gavest him for son to Thine own most beloved Mother.
IV. O my Lord Jesus Christ crucified, Son of the most Blessed Virgin Mary, open Thine arms, and embrace me as Thou didst open them upon the Cross to embrace the whole human race.
V. O my Lord Jesus Christ crucified, Son of the Blessed Virgin Mary, open Thy Heart, and receive therein my heart, and hear me in all that I ask of Thee, if so be it be agreeable to Thy most holy will.
Taken from the Raccolta: His Holiness Pope Pius IX., by a Rescript of May 24, 1859, which is preserved in the Secretary’s Office of the Holy Congregation of Indulgences, vouchsafed to grant:
- the indulgence of 60 days to all the faithful every time that, with contrite heart and devotion, they shall say the following prayers, composed by the Holy Pontiff Pius V., and which he was accustomed to say at the time of his labors and business of importance: provided that the faithful when they say these prayers (known commonly as the Five Credo’s of St. Pius V.) intend to apply them to peace and concord amongst Christian princes, to the extirpation of heresies, and the exaltation of our holy Mother the Church, &c.
- Moreover, to those who for a month together shall have said them every day he granted the plenary indulgence, to be gained on that day when, having Confessed and Communicated, they shall apply them as above directed.
