These days many evangelicals are exploring the more sacramental, liturgical, and historically-conscious church traditions, including Roman Catholicism and Eastern Orthodoxy. This hunger for historical rootedness is a welcome phenomenon – but unfortunately, many assume that this need can only be met outside of Protestant contexts. In this book, Gavin Ortlund draws from both his scholarly work in church history and his personal experience in ecumenical engagement to offer a powerful defense of the Protestant tradition. Retrieving classical Protestant texts and arguments, he exposes how many of the contemporary objections leveled against Protestants are rooted in caricature. Ultimately, he shows that historic Protestantism offers the best pathway to catholicity and historical rootedness for Christians today.
