First Reading
Malachi 1:14–2:2, 8-10
Cursed be the cheat who has a male in his flock, and vows it, and yet sacrifices to the Lord what is blemished; for I am a great King, says the LORD of hosts, and my name is feared among the nations. “And now, O priests, this command is for you. If you will not listen, if you will not lay it to heart to give glory to my name, says the LORD of hosts, then I will send the curse upon you and I will curse your blessings; indeed I have already cursed them, because you do not lay it to heart. But you have turned aside from the way; you have caused many to stumble by your instruction; you have corrupted the covenant of Levi, says the LORD of hosts, and so I make you despised and abased before all the people, inasmuch as you have not kept my ways but have shown partiality in your instruction.” Have we not all one father? Has not one God created us? Why then are we faithless to one another, profaning the covenant of our fathers?
Responsorial Psalm
Psalms 131:1-3
O LORD, my heart is not lifted up, my eyes are not raised too high; I do not occupy myself with things too great and too marvelous for me. But I have calmed and quieted my soul, like a child quieted at its mother’s breast; like a child that is quieted is my soul. O Israel, hope in the LORD from this time forth and for evermore.
Second Reading
1 Thessalonians 2:7-9, 13
But we were gentle among you, like a nurse taking care of her children. So, being affectionately desirous of you, we were ready to share with you not only the gospel of God but also our own selves, because you had become very dear to us. For you remember our labor and toil, brethren; we worked night and day, that we might not burden any of you, while we preached to you the gospel of God. And we also thank God constantly for this, that when you received the word of God which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.
Gospel
Matthew 23:1-12
Then said Jesus to the crowds and to his disciples, “The scribes and the Pharisees sit on Moses’ seat; so practice and observe whatever they tell you, but not what they do; for they preach, but do not practice. They bind heavy burdens, hard to bear, and lay them on men’s shoulders; but they themselves will not move them with their finger. They do all their deeds to be seen by men; for they make their phylacteries broad and their fringes long, and they love the place of honor at feasts and the best seats in the synagogues, and salutations in the market places, and being called rabbi by men. But you are not to be called rabbi, for you have one teacher, and you are all brethren. And call no man your father on earth, for you have one Father, who is in heaven. Neither be called masters, for you have one master, the Christ. He who is greatest among you shall be your servant; whoever exalts himself will be humbled, and whoever humbles himself will be exalted.
