Book excerpt: Penned by a Christian teacher who has led thousands of students through the unfamiliar terrain of systematic theology, A Primer for Christian Doctrine serves as a friendly guide to theology's topics, debates, and terminology. Telling you what you need to know as you begin your study of theology or doctrine, the book is an ideal companion to more comprehensive texts. After a brief introduction defending the continued need for doctrine, Jonathan Wilson clearly and concisely maps out each of the main topics of Christian belief in separate chapters. He also traces the differing emphases of theologians while suggesting reasons for their differences. Whether as a first taste of theology or as a readable summary of its present state, Wilson's Primer for Christian Doctrine will be an invaluable resource for students and small groups pursuing a deeper knowledge of what Christians believe.
