Historical Theology presents the key pillars of the contemporary church and the development of those doctrines as they evolved from the history of Christian thought. Most historical theology texts follow Christian beliefs in a strict chronological manner with the classic theological loci scattered throughout various time periods, movements, and controversies-making for good history but confusing theology. This companion to the classic bestseller Systematic Theology is unique among historical theologies. Gregg Allison sets out the history of Christian doctrine according to a topical-chronological arrangement-one theological element at a time instead of committing to a discussion of theological thought according to its historical appearance alone. This method allows you to: Contemplate one tenet of Christianity at a time, along with its formulation in the early church-through the Middle Ages, Reformation, and post-Reformation era, and into the modern period. Become familiar with the primary source material of Christian history's most important contributors, such as Cyprian, Augustine, Aquinas, Luther, Calvin, Barth, and others. Understand the development of evangelical doctrine with a focus on the centrality of the gospel. Discern a sense of urgent need for greater doctrinal understanding in the whole church. Historical Theology is an easy-to-read textbook for any Christian who wants to know how the church has come to believe what it believes today. Gregg Allison's clear and concise structure make this resource an ideal introduction to Christian doctrine.

Is it time for your church to go multisite? It seems everybody is doing it these days, so how do you know if it is the right solution for your congregation? MultiChurch brings clarity to the multisite movement and assembles the lessons it has learned over the past fifteen years. It explores the opportunities presented by the various forms of multi-site church, identifies areas of concern, and concludes that multisite is not only a biblically sound ecclesiological model, but also a model that provides a compelling solution to contemporary reductionism in the church.

The Unfinished Reformation offers a thoughtful look at the key theological and sociological differences between Catholicism and Protestantism. In 1517 a Catholic monk nailed a list of grievances on the door of a church in Germany and launched a revolution in the history of Christianity. That monk was Martin Luther, and the revolution was the Protestant Reformation. What followed this upheaval was flexibility and innovation in the church but also religious instability and division, particularly among the Catholic and Protestant fault line. Five hundred years later, there continues to be unresolved issues between the Protestant and Catholic churches. So, Gregg Allison and Chris Castaldo ask... is the Reformation really finished? The Unfinished Reformation is a brief and clear guide to the key points of unity and divergence between the two largest branches of Christianity. Fundamental differences in doctrine and practice are addressed in detail: Scripture, Tradition, and Interpretation Image of God, Sin, and Mary Church and Sacraments Salvation Written in an accessible and informative style, The Unfinished Reformation provokes thought about Christian beliefs, equips you for healthy conversations with those on "the other side of the divide", and encourages fruitful discussion about the gospel of Jesus Christ.

Research indicates that on average, Americans change their religious affiliation at least once during their lives. Today, a number of evangelical Christians are converting to Catholicism, Eastern Orthodoxy and Anglicanism. Longtime Evangelicals often fail to understand the attraction of these non-Evangelical Christian traditions. Journeys of Faith examines the movement between these traditions from various angles. Four prominent converts to Eastern Orthodoxy, Catholicism, Evangelicalism and Anglicanism describe their new faith traditions and their spiritual journeys into them. Response chapters offer respectful critiques. Contributors include Wilbur Ellsworth (Eastern Orthodoxy), with a response by Craig Blaising; Francis J. Beckwith (Roman Catholicism), with Gregg Allison responding; Chris Castaldo (Evangelicalism) and Brad Gregory s Catholic response; and Lyle Dorsett (Anglicanism), with a response by Robert Peterson. This book will provide readers with first-hand accounts of thoughtful Christians changing religious affiliation or remaining true to the traditions they have always known. Pastors, counselors and students of theology will gain a wealth of insight into current faith migration within the church today."
