This prayer was a favorite of St. Ignatius of Loyola and was included at the beginning of his Spiritual Exercises. For this reason, it has often been supposed that St. Ignatius is the author of this prayer, but this is incorrect since the prayer was recommended by Pope John XXII and enriched with indulgences by him in the year 1330, nearly 200 years before the time of St. Ignatius of Loyola.

Soul of Christ, sanctify me.
Body of Christ, save me.
Blood of Christ, inebriate me.
Water from the side of Christ, wash me.
Passion of Christ, strengthen me.
O good Jesus, hear me.
Within Thy wounds hide me.
Separated from Thee let me never be.
From the malignant enemy, defend me.
At the hour of death, call me.
And close to Thee bid me.
That with Thy saints I may be
Praising Thee, forever and ever. Amen.
Ignatius of Loyola, St.

St. Ignatius was born in 1491 at Loyola in the Basque area of Northern Spain.  He spent his early years as a courtier and soldier.  After his conversion, he undertook theological studies at Paris where he attracted his first followers, and afterward at Rome he forged this group into the Society of Jesus, better known as the Jesuits.  He and his followers had enormous influence on the preservation and growth of Catholic Faith during Ignatius lifetime and succeeding centuries.  Ignatius, who died in Rome in 1556, is best known for his Spiritual Exercises and his theology of the discernment of spirits.  His liturgical memorial falls on July 31 in the Roman calendar.
