Many people contributed to the publication of this book. Jared W. Ludlow, director of the BYU Religious Studies Center, took an interest in the manuscript from the very start and offered astute comments regarding flow and content. Becky Call, lead editor, did the same, along with Allie Stevens and Emma Taylor, student interns. They were a delight to work with, not simply because they saw ways to improve syntax and phrasing but also because they aligned the references to a uniform style. Brent Nordgren, business and production supervisor, answered critical questions, Leigh Ann Copas steered the manuscript through the publication process, and Alex Socarras creatively masterminded the design and layout of the book. I thank them all for their hard work and amiability. I also thank my earth angel, Janet Knouse Grandy, for her unfailing support and devotion. For over fifty years she has been the wind beneath my wings.
