The Blessing of St. Maurus
There is also a formal, priestly blessing offered to the sick, the Blessing of St. Maurus, that requires either a relic of the True Cross or the St. Benedict Medal. St. Maurus was a disciple of St. Benedict and was his defender against those who persecuted him. Pope St. Gregory the Great described him as a model of religious virtue, especially obedience.
By a decree of the Sacred Congregation of Rites (6 March 1959), the Blessings of St. Maurus over the sick is permitted to be given with a Medal of St. Benedict instead of with a relic of the True Cross, since the latter is difficult to obtain.
Before the blessing is imparted, the relic of the true Cross of our Lord or the medal of St. Benedict is exposed, at least two candles having been lit. Acts of contrition and firm confidence should then be excited in the sick person, so that through the merits and intercession of St. Benedict and St. Maurus, if it should please God, health may be obtained. The Our Father, Hail Mary and Glory be are recited three times in honor of the Blessed Trinity. Then a priest of the Order of St. Benedict, or any priest delegated, having put on a red stole, and with his right hand holding up the relic of the Sacred Cross or the medal of St. Benedict before the sick person, says the following prayers:
V. Benediction and glory, and wisdom, and thanksgiving, honor and power and strength to our God forever and ever.
R. Amen.
V. My foot has stood in the direct way.
R. In the churches I will bless You, O Lord.
Invocation
Through the invocation of the most holy name of the Lord may that faith, in which St. Maurus, by employing the words that follow, healed the sick, and in which I, though an unworthy sinner, utter the selfsame words, restore your health as you desire:
In the name of the most holy and undivided Trinity and supported by the merits of the most holy Father Benedict, I bid you, N., to rise, stand upon your feet and be cured, in the name of the Father and of the Son + and of the Holy Spirit.
Amen.
Antiphon: Surely He has borne our infirmities and carried our sorrows: by His bruises we are healed.
V. He that forgives the iniquities of his creatures.
R. May He heal your infirmities.
V. O Lord, hear my prayer.
R. And let my cry come to You.
V. The Lord be with you.
R. And with your spirit.
V. Let us pray O God, the Creator, of all things, You ordained that Your only Son should take flesh of the Virgin Mary by the power of the Holy Spirit for the restoration of your people and You deigned to heal the wounds and infirmities of our souls by the redemption accomplished upon the sacred and glorious wood of the life-giving Cross: do You also vouchsafe through this powerful sign to restore health to Your servant N. Through the same Christ our Lord.
R. Amen.
V. Let us pray Lord Jesus Christ, You conferred upon the master, blessed Benedict, the privilege of obtaining from You whatsoever he might ask in Your name: vouchsafe, through his intercession, to heal all the infirmities of this Your servant: in order that, being restored to health, he (she) may give thanks to Your holy name.
You live and reign with the Father and the Holy Spirit for ever and ever.
R. Amen.
The Blessing
V. Through the invocation of the Immaculate Mother of God and ever Virgin Mary, and the intercession of Saints Benedict and Maurus, may the Power + of God the Father, the Wisdom + of God the Son, and the Strength + of the Holy Spirit free you from your infirmities. Amen.
May God’s holy will be done, and may it be done to you as you wish and pray, for the praise and honor of the most holy Cross of our Lord Jesus Christ.
The priest then blesses the sick person with the relic of the Cross or the medal of St. Benedict saying:
V. May the blessing of Almighty God, of the Father and of the Son + and of the Holy Spirit descend upon you and abide with you forever.
R. Amen.
The sick person then kisses the relic or the medal of St. Benedict.
This blessing, if need be, may be repeated three times; also three votive Masses might be celebrated, namely in honor of the Passion, of St. Maurus, Abbot, and for the Poor Souls; otherwise the fifteen decades of the Rosary of the Blessed Virgin Mary could be prayed according to the aforesaid intentions by the sick person, or by others in the person’s name.
