The issue at hand is whether the Old Testament law has been abolished. There are many who teach that the Old Testament law has been completely abolished by the New Testament, and that New Testament believers are now under a "law of love," or a "law of grace," that has replaced the Old Testament Law.
This teaching states that only the parts of the Ten Commandments that are restated in the New Testament are binding upon Christians today, and that it is not biblical to divide the Old Testament law into three parts: moral, ceremonial, and civil/judicial, of which the moral part is eternal and universal and the other two parts were temporary.
For a defense of the threefold division of the Old Testament law, check out these articles:
Some argue that Romans 10:4
For Christ is the end of the law for righteousness to everyone who believes.
It is quite clear that Paul here is not at all teaching that the Old Testament law has been abolished. Paul does not say that Christ is the end of the "law," period, but rather, that Christ is the end of the "law for righteousness," or, in other words, the end of trying to earn a right standing before God.
Jesus is the only means through which righteousness can be attained. It is not through the law that any person can become righteous.
Although there are places where Paul speaks harshly about the law, we must gain a balanced view of what Paul thought about the law by considering all of his writings. Paul also said these positive things about the law.
Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.
So the law is holy, and the commandment is holy and righteous and good.
14 For we know that the law is spiritual, but I am of the flesh, sold under sin.
For I delight in the law of God, in my inner being,
