Serious theology is systematic theology. Or so the story goes. Practical theology--with its focus on the church, its life and its practices--has sometimes been understood as the second order application of the  real work of academic theology. However, in this abridged translation of his magisterial Praktische Theologie , Christian Grethlein realizes the rigorous methodology, critical commitments, and expansive sweep of practical theology ​as both an academic and an ecclesial discipline. Grethlein roots his practical theology in communication theory, but does so in a way ordered to a specific end: the communication of the Christian gospel in the present day. He distinguishes practical theology from simply a guide to specific ecclesial praxis, on the one hand, and some general theory of religion, on the other. Grethlein then blends empirical observation with biblical texts to reveal practical theology’s unique nature as a discipline oriented toward rigorous examination of both the gospel and the intentional ways in which it is shared. In so doing, Grethlein opens the possibility of a truly encyclopedic and embedded practical theology.  Part 1 provides a historical introduction to practical theology, positioning it on a global stage, and in relation to other academic disciplines--particularly the modern sciences--as well as within ecclesial and theological traditions. In part 2 Grethlein develops practical theology as communication of the gospel by examining the hermeneutical, empirical, and theological foundations necessary for a systematic practical theology. In part 3 Grethlein turns his attention to ways the gospel is communicated both in time and place, as well as the forms of that communicating (telling, talking, preaching, praying, and singing). In An Introduction to Practical Theology , Christian Grethlein offers students the foundations and frameworks for practical theology while guiding its scholars in the crafting of their academic discipline. A welcome volume on an important subject to church practitioners who take theology seriously -- Barry K. Morris ― Reading Religion A significant addition to the literature on practical theology. ― Choice Students, teachers, and practical theologians will find this work immeasurably helpful. Grethlein offers key insights into developing areas of practical theology that need to be considered. The survey of history, theology, and social sciences provides a foundational introduction to practical theology. -- Scott Donahue-Martens ― Homiletic …This three-part book offers something new to scholars, students and practitioners of Practical Theology, with several positive features. The first part introduces readers both to past and contemporary German scholarship in practical theology, supported by the literature sections throughout the book. Secondly, from his German perspective, Grethlein provides a comparative critical study of Practical Theology in Catholicism and the United States and thus provides a new and challenging method for practical theologians to engage in a global conversation. -- Prasad D. R. J. Phillips ― Expository Times Grethlein's An Introduction to Practical Theology is an important review and updating of the crucial topic of 'practical theology' for the theological world. His work expands the subject of practical theology by complexifying its longstanding attention to the contextual and practice-focused character of faith. Theological attention to the complexity of communication itself is a real gift, and while this practical theology is written from a German perspective, its insights are widely applicable. -- Mary McClintock Fulkerson, Professor of Theology, Duke Divinity School Christian Grethlein is Professor of Practical Theology at Westfalian Wilhelms-University.
