This book is a slight revision of my doctoral dissertation, which was completed at Emory University in 2004. During its writing I have benefited immensely from the generosity of others. Special gratitude is here expressed for the financial support provided by the Graduate Division of Religion at Emory University and the Christian Scholarship Foundation. Even more valuable was the knowledge and wisdom of the faculty at Emory, particularly Peter Bing, Luke T. Johnson, and Walter T. Wilson. My advisor, Carl R. Holladay, has given gifts from his mind and time that demand my most profound gratitude and admiration.
