Hebrews 7:11-19

If the priesthood of Levi and Aaron, which provided the framework for the giving of the law, could really make people perfect, there wouldn’t have been need for a new priesthood like that of Melchizedek. But since it didn’t get the job done, there was a change of priesthood, which brought with it a radical new kind of law. There is no way of understanding this in terms of the old Levitical priesthood, which is why there is nothing in Jesus’ family tree connecting him with that priestly line. But the Melchizedek story provides a perfect analogy: Jesus, a priest like Melchizedek, not by genealogical descent but by the sheer force of resurrection life—he lives!—“priest forever in the royal order of Melchizedek.” The former way of doing things, a system of commandments that never worked out the way it was supposed to, was set aside; the law brought nothing to maturity. Another way—Jesus!—a way that does work, that brings us right into the presence of God, is put in its place.
