Religion has emerged as one of the main sectors within which people mobilize for immigrant rights in the contemporary United States, and this book is based on years of empirical research examining these efforts. The idea that religious activists constitute a central segment of immigrant rights advocacy may surprise those observers accustomed to thinking of religious activists as inherently conservative, as exclusively focused on abortion, marriage and gay rights. In fact, many religious activists in the United States are dedicated to what we might call progressive causes, and peace and justice issues, taking up causes similar to those of the Social Gospel movement of the 1920s. This book is based on fieldwork that Hondagneu-Sotelo conducted over the past five years, mostly in Los Angeles, Orange County, and San Diego, but also in Sacramento, San Francisco, Chicago, and Arizona. All of the case studies focus on faith-based organizations that are working to expand immigrant labor, civil or social rights. The most interesting part of the book is the investigation of how Muslim groups have navigated the tenuous ground they tread in the US--if they adopt a religious stance, they are accused of being ‘terrorists' so mostly they've advocated for civil liberties on secular groups. Christian groups adopt a different more religious stance often based on tenets of ‘liberation theology.' Jewish groups have used both religious and secular approaches to engagement in progressive work on behalf of immigrants.
