Please take your distasteful, egregious accusations elsewhere. Thank you.
I was too quick to respond. My earlier comments were egregious. I have left them without edit to serve as a bad example.
I typed your query, "what is the role of jewish law in the new testament" into google and this is the first article it returned. It will take a couple minutes to read. But answers your question in a very complete fashion with references.

Here is an excerpt:
"THE END OF THE MOSAIC LAW AS A RULE OF LIFE
THE FACT ESTABLISHED
Several passages of Scripture clearly establish that the coming of Christ has brought an end to the Mosaic Law. Paul specifically states that “Christ is the end of the law for righteousness to everyone who believes” (Rom. 10:4). This instituted a new law or principle of life, i.e., the law of the Spirit, the one of liberty and grace (Rom. 8:2, 13). This fact was also clearly settled by the Jerusalem Council in Acts 15. A council was convened in the church at Jerusalem to look into the issue of the Law and its place in the life of believers because some were saying “Unless you are circumcised according to the custom of Moses, you cannot be saved,” and because even certain of the Pharisees who had believed were also saying “It is necessary to circumcise the Gentiles and to order them to observe the law of Moses.” The conclusion of the council, consisting of apostles and elders, was to reject the concept of placing New Testament believers under the yoke of the Law (15:6-11). The only thing the Jerusalem Council asked was that Gentile believers control their liberty in matters that might be offensive to Jewish believers, but they did not seek to place the believers under the yoke of the Law for they realized the Law had come to an end.
Finally, the book of Hebrews demonstrates that the old covenant of the Mosaic Law was only
temporary and has been
replaced by the coming of Christ whose ministry is based on (1) a better priesthood, one after the order of Melchizedek which is superior to Aaron’s, and (2) a better covenant with better promises (see Heb. 7-10). The old covenant was only a shadow of heavenly things, and if it had been able to make men perfect before God there would have been no occasion for a second or new covenant (see Heb. 7:11-12; 8:1-13). This change in the priesthood also necessitates a change in the Law. Such a change shows the Law has been terminated or done away."
Galatians Chapter 3 compares the Law with grace. It is a common text that demonstrates from one of the earliest Christian text, that the Law was viewed as fulfilled by Christ's substitutionary death on the cross. Further that following that law after it had been fulfilled was "foolish," "ignorant," and "bewitched."
