Attributed to Father Marcello Mastrilli, S.J., 17th century.
St. Francis Xavier appeared to Fr. Mastrilli and bidding him renew the vow to go to Japan, said to him:
“All those who implore my help daily for nine consecutive days, from the fourth to the twelfth of March inclusive and worthily receive the Sacraments of Penance and Holy Communion on one of the nine days will experience my protection and may hope with entire assurance to obtain from God any Grace they ask that is for the good of their souls and the glory of God.”
This Novena prayer was passed down through the ages:
“Most amiable and most loving Saint Francis Xavier, in union with thee I reverently adore the Divine Majesty. I rejoice exceedingly on account of the marvellous 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 favour I ask in this novena.
Mention requests here…
In asking this favour, 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, Saint Francis Xavier.
R. That we may be made worthy of the promises of Christ.
O God, Who didst vouchsafe, by the preaching and miracles of Saint 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 3 Our Father’s and 3 Hail Mary’s in memory of Saint Francis Xavier’s devotion to the Most Holy Trinity, and Glory be 10 times in thanksgiving for the graces received during his 10 years of apostleship.
Though St. Francis Xavier mentioned the time when the Novena should be made, yet its efficacy is not restricted to those days, but it may be made any time, and forms a fitting preparation for the feast of the saint, 24 November to 2 December, with his feast being on December 3.
