Hebrews 7:12

The priesthood was such a major part of the whole Mosaic Covenant that this predicted change in the priesthood signaled a change in the whole Covenant. This verse is one of the clearest single statements in the New Testament indicating that God has terminated the Mosaic Law (Covenant; cf. Romans 10:4). Paul went on to say that Christians, therefore, are not under it (Romans 6:14-15; Galatians 3:24-25; Galatians 5:1; Galatians 6:2; 2 Corinthians 3:7-11). That is, it is not what God has given to regulate the lives of Christians.

"If Christ is our high priest today, then there has to be a change in the law, since He could not qualify as a priest under the Levitical arrangement (being of the tribe of Judah). If the law has not been done away today, then neither has the Levitical priesthood; but if Christ is our high priest, we cannot be under the law. Every prayer offered in the name of Christ is an affirmation of the end of the law." [Note: Charles C. Ryrie, "The End of the Law," Bibliotheca Sacra 124:495 (July-September 1967):244. Cf. Morris, p. 67; and Hal Harless, "The Cessation of the Mosaic Covenant," Bibliotheca Sacra 160:639 (July-September 2003):349-66.]

"So by his own independent line of argument our author reaches the same conclusion as Paul: the law was a temporary provision, ’our tutor to bring us unto Christ . . . but now that faith has come, we are no longer under a tutor’ (Galatians 3:24 f.)." [Note: Bruce, p. 145.]
