Dave Black provided me with a link to his article, The Problem of the Literary Structure of Hebrews: An Evaluation and a Proposal, and I wanted to link that here and connect it to the previous post.
Without intending violence to the overall value of the article, I found one of the most helpful parts to be a summary of Vanhoye’s structure and outline. Anything that has the word “chiasm” in it gets at least a second, if not a third, look from me!
