First Reading Ezekiel 33:7-9

7"So you, son of man, I have made a watchman for the house of Israel; whenever you hear a word from my mouth, you shall give them warning from me. 8If I say to the wicked, O wicked man, you shall surely die, and you do not speak to warn the wicked to turn from his way, that wicked man shall die in his iniquity, but his blood I will require at your hand. 9But if you warn the wicked to turn from his way, and he does not turn from his way; he shall die in his iniquity, but you will have saved your life.

Responsorial Psalm Psalms 95:1-2, 6-9

1O come, let us sing to the LORD; let us make a joyful noise to the rock of our salvation! 2Let us come into his presence with thanksgiving; let us make a joyful noise to him with songs of praise! 6O come, let us worship and bow down, let us kneel before the LORD, our Maker! 7For he is our God, and we are the people of his pasture, and the sheep of his hand. O that today you would hearken to his voice! 8Harden not your hearts, as at Mer'ibah, as on the day at Massah in the wilderness, 9when your fathers tested me, and put me to the proof, though they had seen my work.

Second Reading Romans 13:8-10

8Owe no one anything, except to love one another; for he who loves his neighbor has fulfilled the law. 9The commandments, "You shall not commit adultery, You shall not kill, You shall not steal, You shall not covet," and any other commandment, are summed up in this sentence, "You shall love your neighbor as yourself." 10Love does no wrong to a neighbor; therefore love is the fulfilling of the law.

Gospel Matthew 18:15-20

15"If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. 16But if he does not listen, take one or two others along with you, that every word may be confirmed by the evidence of two or three witnesses. 17If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector. 18Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. 19Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. 20For where two or three are gathered in my name, there am I in the midst of them."
