Ezekiel 33: 7-9
33:7 And as for you, son of man, I have made you a watchman to the house of Israel. Therefore, having heard the word from my mouth, you shall announce it to them from me.
33:8 When I say to the impious, ‘O impious man, you will die a death,’ if you have not spoken so that the impious man will keep himself from his way, then that impious man will die in his iniquity. But I will attribute his blood to your hand.
33:9 But if you have announced to the impious man, so that he may be converted from his ways, and he has not converted from his way, then he will die in his iniquity. Yet you will have freed your own soul.
You should owe nothing to anyone, except so as to love one another. For whoever loves his neighbor has fulfilled the law.
13:9 For example: You shall not commit adultery. You shall not kill. You shall not steal. You shall not speak false testimony. You shall not covet. And if there is any other commandment, it is summed up in this word: You shall love your neighbor as yourself.
13:10 The love of neighbor does no harm. Therefore, love is the plenitude of the law.
Matthew 18: 15-20
18:15 But if your brother has sinned against you, go and correct him, between you and him alone. If he listens to you, you will have regained your brother.
18:16 But if he will not listen you, invite with you one or two more, so that every word may stand by the mouth of two or three witnesses.
18:17 And if he will not listen to them, tell the Church. But if he will not listen to the Church, let him be to you like the pagan and the tax collector.
18:18 Amen I say to you, whatever you will have bound on earth, shall be bound also in heaven, and whatever you will have released on earth, shall be released also in heaven.
18:19 Again I say to you, that if two of those among you have agreed on earth, about anything whatsoever that they have requested, it shall be done for them by my Father, who is in heaven.
18:20 For wherever two or three are gathered in my name, there am I, in their midst.”
