The propers (i.e. the prayers and readings) for the Feast of St. Benedict in the Tridentine Mass are simply taken from the Common of Abbots. However, tucked in the back of many hand missals is a section of propers "In Some Places and Congregations." That section gives the special propers unique to the Feast of St. Benedict when said in Benedictine Churches. In the Angelus Press Daily Missal, these may be found on page 1641. They are as follows:
INTROIT
Let us all rejoice in the Lord, celebrating a festival day in honor of Saint Benedict the Abbot, on 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, on His holy mountain. Glory be to the father. (Ps. 47:2) Let us all rejoice in the Lord, celebrating a festival day in honor of Saint Benedict the Abbot, on whose solemnity the Angels rejoice and give praise to the Son of God.
COLLECT
O Almighty and Eternal God, Who didst on this day lead Thy most holy Confessor Benedict out of the prison of the flesh and raise him up to heaven, grant, we pray, the pardon of all sin to Thy servants who celebrate this feast, so that while with glad hearts they rejoice at his glory, they may also by his intercession hav epart in his merits. Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, God, world without end. Amen.
EPISTLE
Ecclus. 50:111,13,14
Behold the great confessor who in his life propped up the house, and in his days fortified the temple. By him also the height of the temple was founded, the double building and the high walls of the temple. In his days the wells of water flowed out, and they were filled as the sea above measure. He took care of his nation, and delivered it from destruction. He prevailed to enlarge the city, and obtained glory in his conversation with the people: and enlarged the entrance of the house and the court. He shone in his days as the morning star in the midst of a cloud, and as the moon at the full. And as the sun when it shineth, so did he shine in the temple of God. And as the rainbow giving light in the bright clouds, and as the flower of roses in the days of the spring, and as the lilies that are on the brink of the water, and as the sweet smelling frankincense in the time of summer. As a bright fire, and frankincense burning in the fire. As a massy vessel of gold, adorned with every precious stone. As an olive tree budding forth, and a cypress tree rearing itself on high. About him was the ring of his brethren: and as the cedar planted in mount Libanus, so as branches of him, and all the sons of Aaron in their glory.
GOSPEL
Matthew 19:27-29
Then Peter answering, said to him: Behold we have left all things, and have followed thee: what therefore shall we have? And Jesus said to them: Amen, I say to you, that you, who have followed me, in the regeneration, when the Son of man shall sit on the seat of his majesty, you also shall sit on twelve seats judging the twelve tribes of Israel. And every one that hath left house, or brethren, or sisters, or father, or mother, or wife, or children, or lands for my names sake, shall receive an hundredfold, and shall possess life everlasting.
SEQUENCE
Laeta quies magni ducis
The happy death of our great Leader bringing the benefits of a new day is commemorated now.
To the pious mind charity is given; so let first resound in a heart aflame with love what is brought forth in song and ceremony.
As along the pathway of the East he rises, let us admire the splendor of our patriarch.
The numerous race that from him sprang makes him shine as the sun, make him like another Abraham.
A raven you see ministering to him while as Elias he hides within a humble cave.
He appears another Eliseus when he calls back the axe from the torrent's rocky depth.
Purity of life make him another Joseph, knowledge of the future makes him another Jacob.
May he be mindful of his family, and bring us to the joys of Christ Who lives forever. Amen.
