First Reading 2 Tim 4:1-5
I charge thee, before God and Jesus Christ, who shall judge the living and the dead, by his coming, and his kingdom: Preach the word: be instant in season, out of season: reprove, entreat, rebuke in all patience and doctrine. For there shall be a time, when they will not endure sound doctrine; but, according to their own desires, they will heap to themselves teachers, having itching ears: And will indeed turn away their hearing from the truth, but will be turned unto fables. But be thou vigilant, labour in all things, do the work of an evangelist, fulfil thy ministry. Be sober.
Responsorial Psalm Ps 40:2, 4, 7-8a, 8b-9, 10, 11
With expectation I have waited for the Lord, and he was attentive to me.
And he put a new canticle into my mouth, a song to our God. Many shall see, and shall fear: and they shall hope in the Lord.
Sacrifice and oblation thou didst not desire; but thou hast pierced ears for me. Burnt offering and sin offering thou didst not require: then said I, Behold I come. In the head of the book it is written of me
then said I, Behold I come. In the head of the book it is written of me that I should do thy will: O my God, I have desired it, and thy law in the midst of my heart.
I have declared thy justice in a great church, lo, I will not restrain my lips: O Lord, thou knowest it.
I have not hid thy justice within my heart: I have declared thy truth and thy salvation. I have not concealed thy mercy and thy truth from a great council.
Gospel Matt 5:13-19
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.
