Eric Schrag did a little studying about the Law we're given in the New Testament. He looked up many verses and put a lot of work into putting something together explaining the strictness and applicability of the Law laid out in the NT versus the Law given in the Hebrew Scriptures. What I want to do here is just to give a few verses that deal with the idea of the Law, rather than specific commands...
Acts 24:14-15 But this I confess to you, that according to the Way, which they call a sect, I worship the God of our fathers, believing everything laid down by the Law and written in the Prophets, (15) having a hope in God, which these men themselves accept, that there will be a resurrection of both the just and the unjust.
Acts 25:8 Paul argued in his defense, "Neither against the law of the Jews, nor against the temple, nor against Caesar have I committed any offense."
Acts 28:23-24 When they had appointed a day for him, they came to him at his lodging in greater numbers. From morning till evening he expounded to them, testifying to the kingdom of God and trying to convince them about Jesus both from the Law of Moses and from the Prophets. (24) And some were convinced by what he said, but others disbelieved.
Romans 2:12-16 For all who have sinned without the law will also perish without the law, and all who have sinned under the law will be judged by the law. (13) For it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified. (14) For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. (15) They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them (16) on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.
Romans 3:31 Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.
Romans 7:12 So the law is holy, and the commandment is holy and righteous and good.
Romans 7:22 For I delight in the law of God, in my inner being,
Romans 8:4 in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.
Romans 13:8 Owe no one anything, except to love each other, for the one who loves another has fulfilled the law.
1 Corinthians 9:8-10 Do I say these things on human authority? Does not the Law say the same? (9) For it is written in the Law of Moses, "You shall not muzzle an ox when it treads out the grain." Is it for oxen that God is concerned? (10) Does he not speak entirely for our sake? It was written for our sake, because the plowman should plow in hope and the thresher thresh in hope of sharing in the crop.
1 Corinthians 14:33-34 For God is not a God of confusion but of peace. As in all the churches of the saints, (34) the women should keep silent in the churches. For they are not permitted to speak, but should be in submission, as the Law also says.
1 Timothy 1:8 Now we know that the law is good, if one uses it lawfully,
James 2:8 If you really fulfill the royal law according to the Scripture, "You shall love your neighbor as yourself," you are doing well.
James 4:11-12 Do not speak evil against one another, brothers. The one who speaks against a brother or judges his brother, speaks evil against the law and judges the law. But if you judge the law, you are not a doer of the law but a judge. (12) There is only one lawgiver and judge, he who is able to save and to destroy. But who are you to judge your neighbor?
