“God has spoken,” says the opening sentence of Hebrews. And as that astonishing sentence unfolds, it exhibits a balance and symmetry that cries out to be diagrammed. Or cartooned, even if only with the restricted means of Microsoft Word.
Here is the chart I habitually draw during class discussions of Hebrews 1. This is just the skeleton, but the rest of the details of the passage can be hung from it. In fact, a fairly adequate biblical theology of the whole canon can be hung from it: You have room to explore the continuity (the one God speaks in these two epochs) along with the discontinuity (he spoke in those ways then, but in this way now).
