Take a look at Timothy George's post from three days ago: Reading the Psalms with the Reformers. An excerpt: "The Reformation of the sixteenth century can be understood in various ways, but it was in essence a biblical revolution, at the heart of which were the Psalms." The subject of George's post is the first volume of Reformation Commentary on Scripture, compiled and edited by Dutch scholar Herman J. Selderhuis. This is a compendium of commentary on the Psalms by well-known Reformation-era Christians. The second volume is forthcoming.
George is the general editor of InterVarsity Press's multi-volume series Reformation Commentary on Scripture of which this volume is part.
