Scott Clark's new book, Recovering the Reformed Confession (from P & R), will be released in November 2008.
Having read several draft chapters, all I can say is this volume will provoke much discussion about what it means to be Reformed in our doctrine, as well as in our practice (preaching, sacraments, catechism, worship, and piety).
Not everyone will agree with Dr. Clark about every point he raises. But this book will certainly provoke a discussion Reformed Christians need to have. The book will force us to deal with this basic question--"are we going to be Reformed in both our theology and practice, or are we going to be Reformed in our theology, but remain evangelicals in our practice?"
