Hebrews 7: A priesthood that does not end at a grave

The Book of Hebrews takes a tiny Genesis appearance and makes it bear a large priestly argument. Melchisedec arrives without the genealogy and death notice expected around a priestly line, receives Abraham's tithe, and blesses the patriarch who already holds the promises. That encounter lets the letter imagine a priesthood outside Levi before Levi exists. Psalm 110 then supplies the decisive later word: another priest will arise "after the order of Melchisedec." If the Levitical arrangement had brought the final perfection, that promise would be difficult to explain. Jesus comes from Judah, so his priesthood cannot be ordinary succession within Aaron's line. Its basis is instead "the power of an endless life," strengthened by God's oath. Mortality made the former priests many; Jesus' continuing life removes the succession problem entirely. The chapter ends where its logic has been heading: the priest is also the offering. He does not repeatedly sacrifice himself. His one self-offering and his unending intercession belong together without confusion.
