Evangelicalism is not commonly known for mining the rich theological heritage handed down from previous generations. Instead, it tends to follow what, in the worst cases, can look like a "me and my Bible" approach to theology. But lately there has been a restlessness among evangelicals—an aching for theological rootedness that has led some to abandon Protestantism altogether. This book aims to set forth a vision for how engaging historical theology can enrich and strengthen the church today—and highlight how it can be done without abandoning a Protestant identity. By addressing two key doctrines—the doctrines of God and the atonement—and drawing from neglected theologians—Boethius, Gregory the Great, and John of Damascus—this book charts a course for evangelicals eager to draw from the past to meet the challenges of the present.
