The latest issue of New Testament Studies has a couple of articles on Hebrews:
Jean-René Moret. "Le rôle du concept de purification dans l’Épître aux Hébreux : une réaction à quelques propositions de David M. Moffitt."
David M. Moffitt has recently put forward an interpretation of Hebrews whereby purification is understood as a victory of life over death, and atonement is effected by the resurrected life of Jesus entering the heavenly sanctuary. We discuss this reading and defend an alternative whereby the moral category of sin is the final target of purification and the notion of ransom, life given in death in place of another life, is key for understanding atonement in Hebrews.
