+Mt 5: 20-26
I tell you, unless your righteousness surpasses that of the scribes and Pharisees, you will not enter into the kingdom of heaven.
“You have heard that it was said to your ancestors, ‘You shall not kill; and whoever kills will be liable to judgment.’
But I say to you, whoever is angry with his brother will be liable to judgment, and whoever says to his brother, ‘Raqa,’ will be answerable to the Sanhedrin, and whoever says, ‘You fool,’ will be liable to fiery Gehenna.
Therefore, if you bring your gift to the altar, and there recall that your brother has anything against you,
leave your gift there at the altar, go first and be reconciled with your brother, and then come and offer your gift.
Settle with your opponent quickly while on the way to court with him. Otherwise your opponent will hand you over to the judge, and the judge will hand you over to the guard, and you will be thrown into prison.
Amen, I say to you, you will not be released until you have paid the last penny.

The Catechism of the Catholic Church
“Teacher, what must I do . . .?”
2052 “Teacher, what good deed must I do, to have eternal life?” To the young man who asked this question, Jesus answers first by invoking the necessity to recognize God as the “One there is who is good,” as the supreme Good and the source of all good. Then Jesus tells him: “If you would enter life, keep the commandments.” And he cites for his questioner the precepts that concern love of neighbor: “You shall not kill, You shall not commit adultery, You shall not steal, You shall not bear false witness, Honor your father and mother.” Finally Jesus sums up these commandments positively: “You shall love your neighbor as yourself.”
2053 To this first reply Jesus adds a second: “If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me.” This reply does not do away with the first: following Jesus Christ involves keeping the Commandments. The Law has not been abolished, but rather man is invited to rediscover it in the person of his Master who is its perfect fulfillment. In the three synoptic Gospels, Jesus’ call to the rich young man to follow him, in the obedience of a disciple and in the observance of the Commandments, is joined to the call to poverty and chastity. The evangelical counsels are inseparable from the Commandments.
2054 Jesus acknowledged the Ten Commandments, but he also showed the power of the Spirit at work in their letter. He preached a “righteousness [which] exceeds that of the scribes and Pharisees” as well as that of the Gentiles. He unfolded all the demands of the Commandments. “You have heard that it was said to the men of old, ‘You shall not kill.’ . . . But I say to you that every one who is angry with his brother shall be liable to judgment.”
2055 When someone asks him, “Which commandment in the Law is the greatest?”Jesus replies: “You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the greatest and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments hang all the Law and the prophets.” The Decalogue must be interpreted in light of this twofold yet single commandment of love, the fullness of the Law:
The 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.” Love does no wrong to a neighbor; therefore love is the fulfilling of the law.
