This book is specifically designed to be used as a textbook for our course called Introduction to Christianity. The course, developed more than a decade ago, is designed to provide our students with a general introduction to the Christian religion, giving particular emphasis to the biblical, historical, and theological traditions within Christianity. In addition to its primary purpose as a textbook, we hope that the book might also prove useful to anyone who may be interested in Christianity, from non-Christian inquirers to lay persons in weekly Sunday-school classes.The book is divided into four major units. The first section explores the Old Testament. The second section provides an overview of the New Testament. The third section delves into Christian history beginning with the early centuries and moving through the Middle Ages, Reformation, and into the modern era. The final section asks questions such as What do Christians believe? and What do Christians do?Accessibly written, this best-selling text is now available in a new edition with more than 50 percent new material.
