Where does it say that the Old Testament Commandments are null and void?

Nowhere. In fact, Jesus told the rich young man to follow the Commandments.

For Christians, Jesus fulfilled the Law of Moses.

Christians are not held to the ceremonial parts of the Mosaic Law concerning of dietary purity and temple worship.

Christians are held to the moral law of God, some of which is expressed in the Ten Commandments.

However Jesus took the Ten Commandments to the next step summarizing them into the two Great Commandments:

+ You shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.

+ You shall love your neighbor as yourself.

And teaching things like

+ Everyone who looks at a woman with lust has already committed adultery with her in his heart.

+ Everyone is our neighbor including our enemies.

Therefore we have to go much farther than the original recipients of the Ten Commandments ever dreamed.

With love in Christ.

Hebrews chapters 8 and 9.

Jeremiah chapter 31

1 Corinthians chapter 11

2 Corinthians chapter 3

In all of these passages, it states that Jesus entered into a new covenant with mankind, enacted at the time of his death. This new covenant does not annul the old covenants (Abraham, David, Moses, etc.), but, according to scripture, does supercede them.

Nowhere does it say that old testament commandments are null and void. Indeed, in the book of John, Jesus states that he is the fullfillment of those laws. There are several episodes in the New Testament, however, where Jesus directly challenges the law of Moses.

The clearest of these is in the book of John. When Jesus arrives at Mount Olive, he finds a group of people preparing to stone a woman to death for adultery, according to the law. Jesus prevents this from occuring and told the woman that he would not condemn her, regardless of the law of Moses.

In the NT Jesus is asked about the commandments many times. He reinstated many of them. You can find them throughout the New Testament. I used to have them all marked, but lost the Bible in a house fire and haven't had time to mark the new one yet. The most important thing is that He added one that was not there - love your neighbor as you love yourself and did not mention one in the NT at all - Remember the Sabbath Day to keep it holy. Want to make the Seventh Day Adventists rant and rave? Tell them that one! The Bible says that if the old covenant had been perfect, then Jesus wouldn't have had to come to the earth. But, it wasn't, and He came and made a perfect covenant. I hope that helped. Sorry I couldn't use specific verses. I'm getting older and have a hard time quoting any more.

Well, for Jews, the commandment are NOT null and void, obviously, as they are eternal. Non-Jews were never expected to follow the commandments anyway.

I don't understand why Christians say that the commandments should be null and void, since Jesus said:

"Do not think that I have come to abolish the Law and the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the law until everything is accomplished."?

(Matt. 5:17-18)

Nowhere.

Jesus orders Christians to follow the Old Testament's laws: "Do not think that I [Jesus] have come to abolish the Law (the Old Testament) or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke or a pen, will by any means disappear from the Law (the Old Testament) until everything is accomplished. (Matthew 5:17-18)" It is clear from these verses from the New Testament that Jesus peace be upon him did honor the Old Testament and did say that every single "letter" of it has to be honored, followed and fulfilled.

God knows best

Peace and Love

Matthew 19:

16 And behold, one came up to him, saying, "Teacher, what good deed must I do, to have eternal life?"

17 And he said to him, "Why do you ask me about what is good? One there is who is good. If you would enter life, KEEP THE COMMANDMENTS."

Revelation 12

[17 Then the dragon was angry with the woman, and went off to make war on the rest of her offspring, on those who KEEP THE COMMANDMENTS of God and bear testimony to Jesus. And he stood on the sand of the sea.

Some people confuse the law with the cammandments. they are not the same thing. We are not bound to the law,for if we were, then the Gospel message would only be for the Jews, and not the Gentiles (us).

The Ten Commandments are moral laws binding on all mankind, for regardless of what faith a person is. There are serious consequences for breaking them, either on a social or personal level.

I don't know what you mean by replacement theology. If you mean infused or imputed righteousness, it is a doctrine invented in the 16th century, and it is false. Some people, inluding Martin Luther, think you can disregard the commandments and still go to heaven. that is NOT what the Bible teaches, and not what was taught by the historic Church.

Psalm 51:1-2 - O God, blot out my transgressions, wash me thoroughly from my iniquity and cleanse me from my sin.

This cleansing requires an inner change of heart. Many Protestants believe that we are so depraved that God only covers our sins up by declaring us righteous (imputing Christ’s righteousness to us). The Catholic (and Scriptural view), however, is that God is powerful enough to blot out our sins and remove them. The view that God just declares us righteous by “covering us up,” denigrates the role of the Holy Spirit in our lives, who continues the work of Christ through His work of justification and sanctification (infusing His grace into souls and changing the inner person).

Jesus and his disciples and the Old Covenant is found in Matthew 5:17-20

Matthew 5:17 says, "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 5:18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. 5:19 Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. 5:20 For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven."

Jesus said he fulfilled the Law of Moses, not to do away with it. Many things changed but the 10 Commandments still stand.

I* am not Christian BUT I can reply easily The Ten Commandments are part of the laws that Jesus preached so ably on in ministry

Jesus didn't replace them. He only FULFILLED them

Rom 3:19-22

19 Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. 20 Therefore no one will be declared righteous in his sight by observing the law; rather, through the law we become conscious of sin.

21 But now a righteousness from God, apart from law, has been made known, to which the Law and the Prophets testify. 22 This righteousness from God comes through faith in Jesus Christ to all who believe.

(from New International Version)

Rom 3:31

31 Do we, then, nullify the law by this faith? Not at all! Rather, we uphold the law.

(from New International Version)

Rom 4:13-16

14 For if those who live by law are heirs, faith has no value and the promise is worthless, 15 because law brings wrath. And where there is no law there is no transgression.

16 Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham's offspring-not only to those who are of the law but also to those who are of the faith of Abraham.

(from New International Version)

Rom 8:1-4

8:1 Therefore, there is now no condemnation for those who are in Christ Jesus, 2 because through Christ Jesus the law of the Spirit of life set me free from the law of sin and death. 3 For what the law was powerless to do in that it was weakened by the sinful nature, God did by sending his own Son in the likeness of sinful man to be a sin offering. And so he condemned sin in sinful man, 4 in order that the righteous requirements of the law might be fully met in us, who do not live according to the sinful nature but according to the Spirit.
