First Reading Sirach 27:30--28:9

27 30Anger and wrath, these also are abominations, and the sinful man will possess them. 28 1He that takes vengeance will suffer vengeance from the Lord, and he will firmly establish his sins. 2Forgive your neighbor the wrong he has done, and then your sins will be pardoned when you pray. 3Does a man harbor anger against another, and yet seek for healing from the Lord? 4Does he have no mercy toward a man like himself, and yet pray for his own sins? 5If he himself, being flesh, maintains wrath, who will make expiation for his sins? 6Remember the end of your life, and cease from enmity, remember destruction and death, and be true to the commandments. 7Remember the commandments, and do not be angry with your neighbor; remember the covenant of the Most High, and overlook ignorance. 8Refrain from strife, and you will lessen sins; for a man given to anger will kindle strife, 9and a sinful man will disturb friends and inject enmity among those who are at peace.

Responsorial Psalm Psalms 103:1-4, 9-12

1Bless the LORD, O my soul; and all that is within me, bless his holy name! 2Bless the LORD, O my soul, and forget not all his benefits, 3who forgives all your iniquity, who heals all your diseases, 4who redeems your life from the Pit, who crowns you with steadfast love and mercy, 9He will not always chide, nor will he keep his anger for ever. 10He does not deal with us according to our sins, nor requite us according to our iniquities. 11For as the heavens are high above the earth, so great is his steadfast love toward those who fear him; 12as far as the east is from the west, so far does he remove our transgressions from us.

Second Reading Romans 14:7-9

7None of us lives to himself, and none of us dies to himself. 8If we live, we live to the Lord, and if we die, we die to the Lord; so then, whether we live or whether we die, we are the Lord's. 9For to this end Christ died and lived again, that he might be Lord both of the dead and of the living.

Gospel Matthew 18:21-35

21Then Peter came up and said to him, "Lord, how often shall my brother sin against me, and I forgive him? As many as seven times?" 22Jesus said to him, "I do not say to you seven times, but seventy times seven. 23"Therefore the kingdom of heaven may be compared to a king who wished to settle accounts with his servants. 24When he began the reckoning, one was brought to him who owed him ten thousand talents; 25and as he could not pay, his lord ordered him to be sold, with his wife and children and all that he had, and payment to be made. 26So the servant fell on his knees, imploring him, `Lord, have patience with me, and I will pay you everything.' 27And out of pity for him the lord of that servant released him and forgave him the debt. 28But that same servant, as he went out, came upon one of his fellow servants who owed him a hundred denarii; and seizing him by the throat he said, `Pay what you owe.' 29So his fellow servant fell down and besought him, `Have patience with me, and I will pay you.' 30He refused and went and put him in prison till he should pay the debt. 31When his fellow servants saw what had taken place, they were greatly distressed, and they went and reported to their lord all that had taken place. 32Then his lord summoned him and said to him, `You wicked servant! I forgave you all that debt because you besought me; 33and should not you have had mercy on your fellow servant, as I had mercy on you?' 34And in anger his lord delivered him to the jailers, till he should pay all his debt. 35So also my heavenly Father will do to every one of you, if you do not forgive your brother from your heart."
