Twenty Centuries of Unity and Diversity
September 30, 2002
In this ambitious book, Olson delineates from an evangelical perspective what is and is not authentic Christian belief. Chapters feature such topics as the Bible, God, Jesus and the Church, beginning with an overview of orthodox belief about the topic, citing Scripture, the Church Fathers and noted Christian writers throughout history. Olson then devotes a section to heretical beliefs, and follows this with an examination of diverse non-heretical beliefs among orthodox Christians (including Roman Catholics, Eastern Orthodox believers, and most Protestants). He ends each chapter envisioning greater unity among Christians, despite honest disagreements. While marred by some redundancy and excess verbiage, Olson's writing renders many complex theological concepts surprisingly accessible. And in his attempts to separate heresy from right belief, he acknowledges that those who adhere to beliefs he labels erroneous are usually sincere Christians (he cites wrong belief among fundamentalists, charismatics, liberal Christians and various sects). Attempting to mediate among the myriad dogmas, doctrines and opinions of orthodox Christians is no easy task, and Olson's descriptions of certain right beliefs and heresies (such as the psychological analogy for the Trinity and modalism) are sometimes barely distinguishable. Despite these and other small logical problems, Olson's book contributes greatly to contemporary evangelicalism not only in its impressive survey of many theologies, but also in its use of "The Great Tradition" of Christian belief as an essential guide to orthodoxy.
