The field research on which this book is based owes its existence to a series of small grants. From the University of Pittsburgh we received two grants from the Center of Latin American Studies, and one from each of the following funding sources: University Center for International Studies, Central Research Development Fund, Faculty of Arts and Sciences, and Center for Social and Urban Research. In addition we received grants-in-aid from the American Philosophical Society, the Wenner-Gren Foundation for Anthropological Research, and the Jacobs Fund of Bellingham, Washington. We are grateful to these institutions for their financial support.

It is practically impossible to single out every individual and institution that, in one form or another, helped us to write this book and to carry out the fieldwork on which it is based. Nonetheless we would like to express our appreciation to those who made the most significant contributions. To the congregations of Amistad y Vida and La Luz del Mundo in the cities of Fortín de las Flores, Córdoba, Orizaba, and Zongolica, and of several rural communities in the Córdoba-Orizaba region, and in the cities of Tlaxcala, Puebla, Apizaco, and several rural communities in the Tlaxcala-Pueblan Valley, we are grateful for allowing us to interview a wide range of congregants. We are intellectually and professionally indebted to Paula Kane, Elio Masferrer, Doren Slade, Lisa Moskowitz, Barry Isaac, Keith Brown, Leonard Plotnicov, David Robichaux, and Timothy Murphy, who read parts of the text, made constructive criticisms, suggested changes in style, presentation, and organization, or discussed theoretical or methodological matters. We are especially indebted to Barry Isaac for his invaluable assistance with final manuscript revisions.

We are grateful to Father Xicohtencatl Xochitotzin Ortega from the city of Tlaxcala and Father Manuel Ortiz Caballero of Orizaba for their information and assessments of Amistad y Vida and La Luz del Mundo and the relationship of the Church with evangelists in general. And last but never least, we are deeply indebted to the interviewers and field assistants mentioned earlier. Their dedication and accuracy in collecting data contributed greatly to this book.
