Alister McGrath’s Theology: The Basics is an introduction to and an explanation of the “basic themes, problems, and personalities” of Christian theology, “aimed specifically at those who are approaching it for the first time.” In assuming that the reader knows nothing about the subject, McGrath’s goal is to provide an accessible starting point for the reader who is interested in theology, but unsure about where to begin in a study with such a lengthy, complex, and diverse tradition.
The book is divided into ten chapters, organized loosely along the lines of the Apostle’s Creed, each one dealing with a major theme in Christianity: Faith, God, Creation, Jesus, Salvation, Spirit, Trinity, Church, Sacraments, and Heaven. McGrath delves briefly into the major historical figures who contributed to the understanding of each of these themes. Quoting such august voices as Augustine, Iranaeus, Ignatius, Calvin, Luther, Wesley, Brunner, Barth, and Tillich, McGrath traces the major arguments, agreements, and disagreements throughout the centuries of church history.
Beginning with an historical exploration of the concept of Faith, McGrath illuminates Aquinas’ Five Ways, showing how his “argument from motion” was further developed by William Paley’s clockmaker argument in the late 18th century, before its “plausibility was eroded by the theory of evolution” in the 19th century. He then outlines Blaise Pascal’s understanding of the existence of God as something that we must know, “not only through our reason, but also through our heart.” Next, he consolidates these approaches with a brief exploration of Anselm’s notion of “faith seek[ing] understanding,” before turning to a second aspect of Faith: more than just believing in God’s existence, “faith is about trusting a God who makes promises, and whose promises may be relied upon.” To elucidate this, McGrath guides the reader through Luther’s emphasis that “faith is only as strong as the one in whom we believe and trust; …even a weak faith in someone who is totally reliable is vastly to be preferred to a strong faith in a scoundrel or trickster.”
The section on Creation is particularly interesting, because McGrath explains the ancient Hebrew conception of God’s creation as being a victory over chaos, putting the account of God’s struggle with Leviathan in the book of Job into a rich perspective that would have been understood by the Hebrew people, but is largely lost on the modern Christian reader.
McGrath is an Irish theologian, historian, scientist and an Anglican priest; his own theological position is not highlighted within the text. He is careful to present different sides of theological arguments fairly: while he clearly calls out heretical doctrines of the past such as Arianism, when it comes to the many theological differences that can reasonably be held by bible-believing Christians in friendly opposition to each other, McGrath’s interest is not in making a case for his own perspective, but in providing an overview of the various claims for his student to assess.
One of the valuable features of this book is the manner in which McGrath invites his reader to participate in an active study of the text. He assists the reader in taking on a role not just as a passive recipient of information, but as a student grappling with each of the concepts in order to come to a fuller understanding of their many nuances. Throughout the text, McGrath develops his reader’s ability to “interact with a theological text… in a manageable way.” To this end, at the end of each chapter, he presents an “extract from a leading theologian or theological document… drawn from a variety of Christian traditions, offering… experience of a number of different approaches.” McGrath guides the reader through the process of engagement with these extracts, which are short at first, but grow longer through the book, as the reader learns to examine them carefully and thoroughly, engaging with each concept represented.
This is not a comprehensive book of theology, but it does not purport to be. McGrath keeps in mind his intended reader, the interested beginner, and does a fine job of creating a student of that reader as he guides him through key doctrines of the Church, elucidating some of the variations within the historical theological tradition, and building a solid foundation from which to broaden the study of theology in the future.
