Introit: Ecclesiasticus xv. 5

    In the midst of the Church the Lord opened his mouth: and He filled him with the spirit of wisdom and understanding: He clothed him with a robe of glory, alleluia, alleluia. Ps. It is good to give praise to the Lord and to sing to Thy name, O Most High. ℣. Glory be to the Father.

Collect

    O God, who didst fill blessed Robert, Thy bishop and doctor, with wondrous learning and virtue that he might break the snares of errors and defend the Apostolic See: grant us by his merits and intercession, that we may grow in the love of truth and that the hearts of those in error may return to the unity of Thy Church. Through our Lord.

Epistle: Wisdom vii. 7-14

    Lesson from the book of Wisdom. I wished, and understanding was given me; and I called, and the spirit of wisdom came upon me; and I preferred her before kingdoms and thrones, and esteemed riches nothing in comparison of her. Neither did I compare unto her any precious stone, for all gold in comparison of her is as a little sand, and silver in respect to her shall be counted as clay. I loved her above health and beauty, and chose to have her instead of light, for her light cannot be put out. Now all good things came to me together with her, and innumerable riches through her hands. And I rejoiced in them all; for this wisdom went before me, and I knew not that she was the mother of them all: which I have learned without guile, and communicate without envy and her riches I hide not; for she is an infinite treasure to men: which they that use, become the friends of God, being commended for the gift of discipline.

First and Second Alleluia: Daniel xii. 3

    Alleluia, alleluia. ℣. They that are learned shall shine as the brightness of the firmament. Alleluia. ℣. They that instruct many to justice, as stars for all eternity. Alleluia.

Gospel: Matthew v. 13-19

    + Continuation of the holy Gospel according to St. Matthew. At that time, Jesus said to His disciples: You are the salt of the earth. But if the salt lose its savour, wherewith shall it be salted? It is good for nothing any more but to be cast out, and to be trodden on by men. You are the light of the world. A city seated on a mountain cannot be hid. Neither do men light a candle and put it under a bushel, but upon a candlestick, that it may shine to all that are in the house. So let your light shine before men, that they may see your good works, and glorify your Father who is in heaven. Do not think that I am come to destroy the law, or the prophets. I am not come to destroy, but to fulfill. For amen I say unto you, till heaven and earth pass, one jot, or one tittle shall not pass of the law, till all be fulfilled. He therefore that shall break one of these least commandments, and shall so teach men, shall be called the least in the kingdom of heaven. But he that shall do and teach, he shall be called great in the kingdom of heaven.

Offertory: Psalms lxxii. 28

    It is good for me to adhere to God, to put my hope in the Lord: that I may declare all Thy praises in the gates of the daughter of Sion, alleluia.

Secret

    We offer Thee, O Lord, our oblations in an odor of sweetness: grant that being instructed by the counsels and examples of blessed Robert, we may run with joyful heart in the ways of Thy commandments. Through.

Communion: Matthew v. 15

    You are the light of the world; let your light so shine before men, that they may see your good works and glorify your Father who is in heaven, alleluia.

Postcommunion

    May the Sacraments which we have received, O Lord, our God, maintain in us that ardent charity, wherewith blessed Robert was intensely inflamed, and spent himself constantly for Thy Church. Through our Lord.
