A dear friend passed along this beautiful prayer! The Miraculous Novena of Grace can be prayed March 4th through March 12th or November 25th through December 3rd. Great way to begin Lent!
Prayer to St. Francis Xavier
Attributed to Father Marcello Mastrilli, S.J. (17th century)
"Most amiable and loving St. Francis Xavier, in union with thee I reverently adore the Divine Majesty. I rejoice exceedingly on account of the marvelous gifts which God bestowed upon thee. I thank God for the special graces He gave thee during thy life on earth and for the great glory that came to thee after thy death. I implore thee to obtain for me, through thy powerful intercession, the greatest of all blessings--that of living and dying in the state of grace. I also beg of thee to secure for me the special favor I ask in this novena. (Here you may mention the grace, spiritual or temporal, that you wish to obtain.) In asking this favor I am fully resigned to the Divine Will. I pray and desire only to obtain that which is most conducive to the greater glory of God and the greater good of my soul."
V. Pray for us, St. Francis Xavier.
R. That we may be made worthy of the promises of Christ.
Let us pray:
"O God, Who didst vouchsafe, by the preaching and miracles of St. Francis Xavier, to join unto Thy Church the nations of the Indies, grant, we beseech Thee, that we who reverence his glorious merits may also imitate his example, through Jesus Christ Our Lord. Amen."
Add an Our Father and Hail Mary three times in memory of St. Francis Xavier's devotion to the Most Holy Trinity, and a Glory Be ten times in thanksgiving for the graces received during his ten years of apostleship.
History/Promise: The Novena of Grace, which begins March 4th and ends on the 12th, the day of the canonization of St. Francis Xavier, owes its origin to the Saint himself. At Naples, in December, 1633, Father Marcello Mastrilli, S.J. was at the point of death. The Saint appeared to him and, bidding him renew a vow he had made to labor in Japan, said, "All those who implore my help daily for nine consecutive days, from the 4th to the 12th of March included, and worthily receive the Sacraments of Penance and the Holy Eucharist on one of the nine days, will experience my protection and may hope with entire assurance to obtain from God any grace they ask for the good of their souls and the glory of God."
The Father arose, instantly cured. So well has the Saint kept this promise that this devotion in his honor became universally known as the Novena of Grace. Its efficacy is not restricted to the dates mentioned. It may be made very appropriately from November 25th to December 3rd, the feast of St. Francis Xavier. Though any prayers can be said in honor of the Saint, the foregoing are generally recommended.
