As mentioned in previous posts, the month of October is dedicated to the Holy Rosary.

In 1889 Pope Leo XIII requested for a prayer to be said to Saint Joseph at the end of the Rosary, especially in October.

It’s called To thee, O Blessed Joseph.

It’s sometimes called the October Prayer to St. Joseph.

USCCB explains:

This prayer to Saint Joseph—spouse of the Virgin Mary, foster father of Jesus, and patron saint of the universal Church—was composed by Pope Leo XIII in his 1889 encyclical, Quamquam pluries. He asked that it be added to the end of the Rosary, especially during the month of October, which is dedicated to the Rosary. It may be said after the customary Salve Regina and concluding prayer, and may also be used to conclude other Marian devotions.

The prayer is ordinarily enriched with a partial indulgence (Handbook of Indulgences, conc. 19). During the Year of Saint Joseph, however—which lasts from December 8, 2020 to December 8, 2021—the use of this prayer has been included among those enriched with a plenary indulgence (see Decree of the Apostolic Penitentiary issued Dec. 8, 2020, section E). It may be said on any day of the Year of Saint Joseph, but especially on his various feast days or other devotional days dedicated to St. Joseph:

• December 27, 2020, the Feast of the Holy Family of Jesus, Mary and Joseph
• March 19, 2021, the Solemnity of Saint Joseph, Spouse of the Blessed Virgin Mary
• May 1, 2021, the Optional Memorial of Saint Joseph the Worker
• The nineteenth day of each month
• Every Wednesday, the traditional day of the week for devotions to Saint Joseph
• “St. Joseph Sunday” and suitable days of other liturgical rites in the Eastern Catholic Churches

Since it’s the month of the Rosary and Year of St. Joseph, I encourage you to say this prayer to our beloved spiritual father!

The English and Latin text are below.

The special motives for which St. Joseph has been proclaimed Patron of the Church, and from which the Church looks for singular benefit from his patronage and protection, are that Joseph was the spouse of Mary and that he was reputed the Father of Jesus Christ. From these sources have sprung his dignity, his holiness, his glory.

(Quamquam pluries)

To thee, O Blessed Joseph

To thee, O blessed Joseph, we have recourse in our affliction, and having implored the help of thy thrice holy Spouse, we now, with hearts filled with confidence, earnestly beg thee also to take us under thy protection. By that charity wherewith thou wert united to the Immaculate Virgin Mother of God, and by that fatherly love with which thou didst cherish the Child Jesus, we beseech thee and we humbly pray that thou wilt look down with gracious eye upon that inheritance which Jesus Christ purchased by His blood, and wilt succor us in our need by thy power and strength.

Defend, O most watchful guardian of the Holy Family, the chosen off-spring of Jesus Christ. Keep from us, O most loving Father, all blight of error and corruption. Aid us from on high, most valiant defender, in this conflict with the powers of darkness. And even as of old thou didst rescue the Child Jesus from the peril of His life, so now defend God’s Holy Church from the snares of the enemy and from all adversity. Shield us ever under thy patronage, that, following thine example and strengthened by thy help, we may live a holy life, die a happy death, and attain to everlasting bliss in Heaven. Amen.

Ad te beate Ioseph

Ad te beate Joseph, in tribulatione nostra confugimus, atque, implorato Sponsae tuae sanctissimae auxilio, patrocinium quoque tuum fidenter exposcimus. Per eam, quaesumus quae te cum immaculata Virgine Dei Genetrice conjunxit, caritatem, perque paternum, quo Puerum Jesum amplexus es, amorem, supplices deprecamur, ut ad hereditatem, quam Jesus Christus acquisivit Sanguine suo, benignus respicias, ac necessitatibus nostris tua virtute et ope succurras.

Tuere, o Custos providentissime divinae Familiae, Jesu Christi subolem electam; prohibe a nobis, amantissime Pater, omnem errorum ac corruptelarum luem; propitius nobis, sospitator noster fortissime, in hoc cum potestate tenebrarum certamine e caelo adesto; et sicut olim Puerum Jesum e summo eripuisti vitae discrimine, ita nunc Ecclesiam sanctam Dei ab hostilibus insidiis atque ab omni adversitate defende: nosque singulos perpetuo tege patrocinio, ut ad tui exemplar et ope tua suffulti, sancte vivere, pie emori, sempiternamque in caelis beatitudinem assequi possimus. Amen.
