The purpose of this book is to provide college classes, missionaries and the general reader with a connected survey of the faith and practice of the Church of Jesus Christ of Latter-day Saints. The treatment of the subject is necessarily brief. It would be desirable therefore to make available the suggested reference library to all classes using this book as a text. Nearly all the supplementary readings given at the end of each chapter are drawn from this collection of well-known expositions of "Mormonism." The questions and problems, prepared by J. Wyley Sessions, M. A., and Merrill D. Clayson, M. S., may be used effectively to develop chapter subjects, whether in the class room or as outside assignments. Teachers may well devise other questions and problems suitable to class needs. There is ample material in the book, when the supplementary questions and problems are used, for a three or five hour course throughout the school year. Without the use of the supplementary material, and making such omissions as seem desirable, the chapter subjects lend themselves to a one-hour course throughout the school year. When the book is used in a one-hour semester course, divisions three and five may be omitted except for one class period devoted to each of these divisions, and some other chapter subjects may be dealt with briefly. The title of the book is borrowed from the catalogue name of the course, "Religion 60-B1," offered by the University of Southern California. The lectures given in that course in 1935-36 form the basis of this book.
