Saint Thomas Aquinas
Introit
Ecclesiasticus 15:5
In the midst of the Church the Lord opened his mouth: and filled him with the spirit of wisdom and understanding: He clothed him with a robe of glory. 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, through Whom Thy Church is glorified by the wonderful learning of Thy blessed Confessor Thomas and profiteth still from his holy labours: grant, we pray, that we may grasp his teaching with our minds and show it, as he did, in our lives. Through our Lord.
Epistle
Wisdom 7:7-14
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.
Gradual
Psalm 36:30-31
The mouth of the just shall meditate wisdom, and his tongue shall speak judgment. The law of His God is in his heart: and his steps shall not be supplanted.
Tract
Psalm 111:1-3
Blessed is the man that feareth the Lord: he shall delight exceedingly in His commandments. His seed shall be mighty upon earth: the generation of the righteous shall be blessed. Glory and wealth shall be in his house: and his justice remaineth for ever and ever.
Gospel
Matthew 5:13-19
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 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 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 fulfil. 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 so shall 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
Psalm 91:13
The just shall flourish like the palm tree: he shall grow up like the cedar of Libanus.

Communion
