|“|| Leviticus 20:10 And the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbour's wife, the adulterer and the adulteress shall surely be put to death.
John 8:3 And the scribes and Pharisees brought unto him a woman taken in adultery; and when they had set her in the midst,
This involves a distinction between the Old and New Testaments in who has the right to punish, not what the punishment should be. Observe that Jesus never said she wasn't worthy of death.
The New Testament writers, particularly Paul, point out that while the Old Testament Law including Leviticus 20:10 was a just Law (1 Timothy 1:8, Romans 7:7) it declares everyone is guilty of death and by it none will be justified. (Romans 3:20) As Paul says, the Law is just (Romans 7:7, 1 Timothy 1:8), but was just a schoolmaster to show us our faults (Galatians 3:24-25) that we might repent and turn from them (Romans 6:1-2, Galatians 6:7-8, Philippians 3:18-19), forgiving others as God wants so He can forgive us.
|“|| Romans 3:19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
1 John 3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
Romans 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
James 2:10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
Romans 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
1 Timothy 1:8 But we know that the law is good, if a man use it lawfully;
Romans 3:9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
Galatians 3:19 Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.
Romans 3:31 Do we then make void the law through faith? God forbid: yea, we establish the law.
Thus there is no contradiction. Adultery like all sin is worthy of death, but God alone has the authority and position to render that judgment. Since we are all equally guilty of death, we should not sentence others to death unless sinless ourselves, which is all Jesus was pointing out. Notice that Jesus did not deny the adulteress was sinful or worthy of death, to the contrary, Jesus told her "go and sin no more." (John 8:11)
Rather than claiming the Old Testament Law's punishments were wrong, the New Testament seen in Romans 3 claims that all are guilty according to the Law, and that we must forgive others their violations of it if we want God to likewise forgive us. (Matthew 6:12, 18:35; Mark 11:25-26) The Law, including Leviticus, was just, but could not justify, and was given to show us our faults and sinfulness.
