Hebrews 7:12
“For the priesthood being changed, there is of necessity a change made also in the law.”
What does Hebrews 7:12 mean?
When the author of Hebrews writes about a change in priesthood, he's referring to Jesus replacing the entire Old Testament priestly system. This wasn't a minor adjustment but a fundamental shift in how people relate to God, so naturally the rules governing that relationship had to change too. Think of it like moving from one country's legal system to another. You can't keep the old laws intact when the entire structure of authority has been transformed. Jesus became our "high priest" in a completely different way than the line of priests descended from Aaron, which meant the old regulations about sacrifices, temple offerings, and priestly duties no longer applied in the same way. The author is reassuring his readers (likely Jewish Christians wrestling with what to do with their traditions) that these changes aren't random or contradictory. They're the natural, necessary outcome of Jesus being who he claimed to be. The old system wasn't bad, but it was always meant to point forward to something better.
