St. Benedict is called the Doctor of humility. He was a prophet and wrought miracles and "was filled with the spirit of all the just" says St. Gregory. (His empire over devils is still exercesed nowadays by the medal of St. Benedtct which works wonders especially in missionary countries where Satan is most powerful.)
Among his sons are counted more than twenty popes, and an immense number of bishops, doctors, apostles, learned men and educators who have deserved well of humanity and of the Church. (Five sons of 8t. Benedict are numbered among the Doctors of the Church. St Augustine of Canterbury converted England; St. Boniface, Germany; St. Amandus, St. Willibrord, St. Anscharius and others brought to the faith more than twenty pagan nations.)
By his life he powerfully co-operated in the work of redemption and his glorious death has made him the patron of holy dying.
Gaudeamus omnes in Domino, diem festum celebrantes sub honore sancti Benedicti Abbatis: de cujus solemnitate gaudent Angeli, et collaudant Filium Dei. * Magnus Dominus et laudabilis nimis: in civitate Dei nostri, in monte sancto ejus.
Let us all rejoice in the Lord, celebrating a festival in honour of the holy Abbot Benedict; at whose solemnity the Angels rejoice, and give praise to the Son of God. * Great is the Lord, and exceedingly to be praised: in the city of our God, in his holy mountain.
(Psalm 47:2 from the Introit of Mass, according to the proper Benedictine Usage)
Omnipotens sempiterne Deus, qui hodierna die carnis eductum ergastulo sanctissimum sublevasti ad coelum: concede, quaesumus, haec festa tuis famulis celebrantibus cunctorum veniam delictorum; ut, qui exsultantibus animis ejus claritati congaudeant, ipso apud te interveniente consocientur et meritis.
O almighty and everlasting God, who didst this day deliver out of the prison of the flesh thy most holy Confessor Benedict and bear him up to heaven, grant, we beseech thee, thy servants, who are celebrating this festival, forgiveness for all sins, that in the gladness wherein they are united in rejoicing at his glory, they may by his intercession before thee partake also in his merits.
(Collect, according to the Benedictine usage)
Dona ferens novae lucis,
Caris datur piae menti,
Corde sonet in ardenti,
Quidquid foris promitur.
Hunc per callem orientis
Amplum semen magnae prolis
Illum fecit instar solis
Corvum cernis ministrantem,
Hinc Eliam latitantem
Specu nosce parvulo.
Cum securis revocatur
De torrentis alveo.
Illum Joseph candor morum,
Illum Jacob futurorum
Mens effecit conscia.
Ipse memor suae gentis,
Nos perducat in manentis.
Semper Christi gaudia.
Joyful rest of our leader, that brings the gift of a new light, we commemorate you today.
Grace is given the loving soul, may our ardent heart be united to the songs of our lips.
By the radiant way going up to the east, let us admire our Father rising to heaven, equal to the patriarchs.
His innumerable posterity, figure of the sun, made him like to Abraham.
See the crow serving him and recognize hence Elias hiding in a little cave.
Recognize Eliseus, when he bids return the axe from beneath the current.
It is Joseph through his life without stain; it is Jacob bringing future things to mind.
May he be mindful of his people, and may he lead us till we behold with him the eternal joys of Christ.
