Book excerpt: Called to Believe is an abridgment and condensation of the more comprehensive text, Called to Believe, Teach, and Confess. It offers an accessible, introductory overview of the major doctrines of Christianity. Written from a Lutheran Christian perspective, this book is a helpful resource for those within that tradition and to others who seek a deeper and broader understanding of Christian teaching. Firmly rooted in Scripture, this book directs the reader back to the Bible. It emphasizes the interrelatedness of all Christian teachings, with its central teaching being the doctrine of justification by grace through faith in Jesus Christ. It also includes the text of the three ecumenical creeds accompanied by a brief introduction to their historical background. This book is ideal as an introductory text for university or advanced high school students and for other Christian adults who seek to expand their knowledge of God's revelation and its application in human lives. It introduces and uses classic theological vocabulary and terminology, while offering clear definitions and application. Key terms, study questions, and a glossary help make this a valuable resource. Suggested readings from Scripture, and secondary sources guide the reader into deeper study.
