I started looking at Hebrews 10 in order to reply to a comment from Chris Wooldridge, who cited the chapter as an example of how Jesus’ death is treated not only as a historical event but also as a theological or metaphysical event.
But you quickly discover that Hebrews 10 is part of a long, dense, tightly woven, intertextual (i.e. it draws extensively on the Old Testament) argument about the significance of Jesus’ death and resurrection for the community of Jewish believers (presumably) to whom the letter is written.
You can’t prise a few statements about Jesus’ death as a one-off sacrifice from it and expect them to stand up on their own as general theological propositions. They don’t. They fall over.
