“Third, the Mosaic Covenant is no longer a functional covenant. The New Testament affirms the fact that the Mosaic Covenant has ceased to function as a valid covenant. Hebrews 8–9 makes it clear that Jesus came as the Mediator of a covenant that replaced the old one. “By calling this covenant ‘new,’ he has made the first one obsolete” (Heb. 8:13). Thus the Mosaic Covenant is no longer functional or valid as a covenant. This has important implications for one’s understanding of the Law. The Old Testament Law specified the terms by which Israel could receive blessings in the land under the Old (Mosaic) Covenant. If the Old Covenant is no longer valid, how can the laws that make up that covenant still be valid? If the Old Covenant is obsolete, should not also the laws in that Old Covenant be seen as obsolete?
Paul stated repeatedly that Christians are not under the Old Testament Law. For example in Galatians 2:15–16 he wrote, “A man is not justified by observing the law, but by faith in Jesus Christ.” In Romans 7:4 Paul stated, “You also died to the law through the body of Christ.” In Galatians 3:25 he declared, “Now that faith has come, we are no longer under the supervision of the law.” Paul argued vigorously against Christians returning to the Old Testament Law. If there was a distinction between civil, ceremonial, and moral laws, it was unusual that Paul ignored it. Furthermore, if the moral laws were to be understood as universally applicable, one would expect Paul at least to use them as the basis for Christian moral behavior. However, as Goldingay points out,
[p.29]
Paul “does not generally base his moral teaching on this foundation but on the nature of the gospel, the guidance of the Spirit, and the practice of the churches.“11
How, then, should Jesus’ words in Matthew 5:17 be understood? He said, “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.” Did Jesus and Paul contradict each other? Not at all. First, the phrase “the Law and the Prophets” refers to the entire Old Testament. So in this verse Jesus was not speaking of only the Mosaic Law. Also the antithesis is not between “abolish” and “observe,” but between “abolish” and “fulfill.” Jesus did not claim that He came to observe the Law or to keep the Law; rather He came to fulfill it. The word (“to fulfill”) occurs numerous times in Matthew, and it normally means, “to bring to its intended meaning.” Jesus was not stating that the Law is eternally binding on New Testament believers. If that were the case, Christians today would be required to keep the sacrificial and ceremonial laws as well as the moral ones, and that would clearly violate other portions of the New Testament.
Jesus was saying that He did not come to sweep away the righteous demands of the Law, but that He came to fulfill its righteous demands. As the climax of this aspect of salvation history, Jesus fulfilled all the righteous demands and all the prophetic foreshadowing of the Law and of the Prophets. In addition Jesus was the final Interpreter of and Authority over the Law and its meaning, as other passages in Mathew indicate. Jesus restated some of the Old Testament laws (19:18–19), but some He modified (5:31–32). Some He intensified (5:21–22, 27–28 ), and others He changed significantly (5:33–37, 38–42, 43–47). Some laws He abrogated entirely (Mark 7:15–19). Jesus was not advocating the continuation of the traditional Jewish approach of adherence to the Law. Nor was He advocating that the Law be dismissed altogether. He was proclaiming that the meaning of the Law must be interpreted in light of His coming and in light of the profound changes introduced by the New Covenant.”
same link as above. Good study…thanks for making me look that up, I learned something! I think that questioning one’s Faith is the only way to strengthen it.
