No one except Yeshua—the Son of God—has the authority to redefine God’s laws. Yeshua did so with God’s permission, as we read in John 6:38:
For I came down from heaven, not to do mine own will, but the will of him that sent me.
Here are the changes Yeshua made regarding:
- Anger and Reconciliation
You have heard that it was said to them of old: Thou shalt not kill. And whosoever shall kill shall be in danger of the judgment. But I say to you, that whosoever is angry with his brother, shall be in danger of the judgment. And whosoever shall say to his brother, Raca, shall be in danger of the council. And whosoever shall say, Thou Fool, shall be in danger of hell fire. If therefore thou offer thy gift at the altar, and there thou remember that thy brother hath any thing against thee; Leave there thy offering before the altar, and go first to be reconciled to thy brother: and then coming thou shalt offer thy gift. Be at agreement with thy adversary betimes, whilst thou art in the way with him: lest perhaps the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison. Amen I say to thee, thou shalt not go out from thence till thou repay the last farthing. (Matthew 5:21–26)
You have heard that it was said to them of old: Thou shalt not commit adultery. But I say to you, that whosoever shall look on a woman to lust after her, hath already committed adultery with her in his heart. And if thy right eye scandalize thee, pluck it out and cast it from thee. For it is expedient for thee that one of thy members should perish, rather than that thy whole body be cast into hell. And if thy right hand scandalize thee, cut it off, and cast it from thee: for it is expedient for thee that one of thy members should perish, rather than that thy whole body be cast into hell. (Matthew 5:27–30)
And it hath been said, Whosoever shall put away his wife, let him give her a bill of divorce. But I say to you, that whosoever shall put away his wife, excepting for the cause of fornication, maketh her to commit adultery: and he that shall marry her that is put away, committeth adultery. (Matthew 5:31–32)
Again you have heard that it was said to them of old, Thou shalt not forswear thyself: but thou shalt perform thy oaths to the Lord. But I say to you not to swear at all, neither by heaven, for it is the throne of God: Nor by the earth, for it is his footstool: nor by Jerusalem, for it is the city of the great king: Neither shalt thou swear by thy head, because thou canst not make one hair white or black. But let your speech be yea, yea: no, no: and that which is over and above these, is of evil. (Matthew 5:33–37)
You have heard that it hath been said, An eye for an eye, and a tooth for a tooth. But I say to you not to resist evil: but if one strike thee on thy right cheek, turn to him also the other: And if a man will contend with thee in judgment, and take away thy coat, let go thy cloak also unto him. And whosoever will force thee one mile, go with him other two, Give to him that asketh of thee and from him that would borrow of thee turn not away. (Matthew 5:38–42)
- Neighbours and Enemies
Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. For if ye love them which love you, what reward have ye? do not even the publicans the same? And if ye salute your brethren only, what do ye more than others? do not even the publicans so? (Matthew 5:43–47)
And Yeshua went unto mount Olivet. And early in the morning he came again into the temple, and all the people came to him, and sitting down he taught them. And the scribes and the Pharisees bring unto him a woman taken in adultery: and they set her in the midst, And said to him: Master, this woman was even now taken in adultery. Now Moses in the law commanded us to stone such a one. But what sayest thou? And this they said tempting him, that they might accuse him. But Yeshua bowing himself down, wrote with his finger on the ground. When therefore they continued asking him, he lifted up himself, and said to them: He that is without sin among you, let him first cast a stone at her. And again stooping down, he wrote on the ground. But they hearing this, went out one by one, beginning at the eldest. And Yeshua alone remained, and the woman standing in the midst. (John 8:1–9)
As you can see, Yeshua redefined quite a few of God’s laws. As the Son of God, only He has the authority to do so. No one else does.
