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. Ps. It is good to give praise to the Lord: and to sing Thy name, O most High. ℣. Glory be to the Father.

Collect

    O God, who dost enlighten Thy Church with the wonderful learning of blessed Thomas, Thy confessor, and dost render it fruitful by his holy works, grant us, we beseech Thee, both to understand that which he taught, and to follow his example in what he practiced. Through our Lord.

Commemoration of the Feria:

Collect

    Grant, we beseech Thee, O Lord, a saving virtue to our fast; that the chastisement of the flesh, which we have taken upon us, may bestow new life to our souls. 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.

Gradual: Psalm xxxvi. 30, 31

    The mouth of the just shall meditate wisdom, and his tongue shall speak judgement. ℣. The law of his God is in his heart: and his steps shall not be supplanted.

Tract: Psalm cxi. 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 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: Psalm cxi. 13

    The just shall flourish like the palm-tree: he shall grow up like the cedar of Libanus.

Last Gospel of the Feria:

Gospel: Luke xv. 11-32

    + The continuation of the holy Gospel according to St. Luke. At that time Jesus spoke to the pharisees and scribes this parable: A certain man had two sons: and the younger of them said to his father: Father, give me the portion of substance that falleth to me. And he divided unto them his substance. And not many days after, the younger son, gathering all together, went abroad into a far country, and there wasted his substance, living riotously. And after he had spent all, there came a mighty famine in that country, and he began to be in want. And he went and cleaved to one of the citizens of that country. And he sent him into his farm to feed swine. And he would fain have filled his belly with the husks the swine did eat: and no man gave unto him. And returning to himself, he said: How many hired servants in my father's house abound with bread, and I here perish with hunger? I will arise, and will go to my father, and say to him: Father, I have sinned against heaven and before thee: I am not worthy to be called thy son: make me as one of thy hired servants. And rising up, he came to his father. And when he was yet a great way off, his father saw him, and was moved with compassion, and running to him fell upon his neck and kissed him. And the son said to him: Father, I have sinned against heaven and before thee, I am not now worthy to be called thy son. And the father said to his servants : Bring forth quickly the first robe, and put it on him, and put a ring on his hand, and shoes on his feet: and bring hither the fatted calf, and kill it, and let us eat and make merry, because this my son was dead, and is come to life again: was lost, and is found. And they began to be merry. Now his elder son was in the field: and when he came, and drew nigh to the house, he heard music and dancing: and he called one of the servants, and asked what these things meant. And he said to him: Thy brother is come, and thy father hath killed the fatted calf, because he hath received him safe. And he was angry, and would not go in. His father therefore coming out began to entreat him. And he answering, said to his father: Behold, for so many years do I serve thee, and I have never transgressed thy commandment, and yet thou hast never given me a kid to make merry with my friends: but as soon as this thy son is come, who hath devoured his substance with harlots, thou hast killed for him the fatted calf. But he said to him: Son, thou art always with me, and all I have is thine: but it was fit that we should make merry and be glad, for this thy brother was dead, and is come to life again: he was lost, and is found.
