I recently noticed that CBD has reduced the price of Paul McGlasson’s Invitation to Dogmatic Theology: A Canonical Approach (Baker 2006). It is now two bucks! You have no excuse not to purchase. As the title indicates, this is an introductory survey of dogmatic theology, with special emphasis on the canon of Scripture’s authority in theology. You will see a lot of influence by Karl Barth and Brevard Childs, who writes the foreword.
While you’re shopping, CBD has Sara Grove’s Nomad documentary for $2.99. You can watch the trailer here. Also, Audio Adrenaline’s Until My Heart Caves In is only $1.99. It includes one of their best singles, “King.”
