Check out the Eerdmans Fall 2016 catalog on page 25. They are reprinting a Mohr Siebeck volume this fall that is one of best books written on Paul that I’ve read. You may be thinking that it is the long awaited Christosis: Engaging Paul’s Soteriology with His Patristic Interpreters, which is, I think, the best book on Paul and theosis out there. In case you haven’t read it or didn’t want to mortgage the house to buy the other version, I argue that Paul’s soteriology overlaps directly with later patristic ideas about theosis; however, with his distinctive emphasis on dying and rising with Christ (through the Spirit), christosis might be a better term to describe his theotic soteriology.
You’d, however, be wrong that it is the hottest reprint of 2016. That prize goes to a phenomenal collection of essays by John Barclay, Pauline Churches and Diaspora Jews. I helped do some minor editing to pull the various essays together, and it was one of the best parts of my PhD days in Durham. While the essays have a general social-historical bent, they address a wide range of issues that will pay long term dividends. When John was picking out the essays, he made a salient point: he thought all the essays he wrote were worthy of being published once, but these are the ones he thought were worthy of being published twice. You will no doubt agree when you read it.
