Mulder, professor of sociology at Calvin College; Ramos, assistant professor of sociology at George Fox University; and Marti, professor of sociology at Davidson College, have teamed up as part of the Latino Protestant Congregation Project, a joint endeavor of Davidson College and Calvin College, to create this cooperative study. By 2030, they write, it is estimated that half of all Latinos in the United States--who currently make up 17% of the population--will be Protestant. The 'Latino Reformation,' as Time named it, has remained largely invisible to the general public, fellow Protestants, and social scientists, in part because few dedicated researchers speak Spanish. But now the Latino Protestant Congregation Project has released its initial substantive and complex findings, examining styles of worship, values, congregation demographics, leadership structures, and sociopolitical perspectives. The fine mix of fresh quantitative data and engaging qualitative case studies gives a rich feel for the diversity of Latino Protestant communities, from a Dutch-Latino Reformed church in Iowa to the non-denominational church in Los Angeles that encourages members to 'transcend' ethnicity. Additionally, the chapter on Latino Protestants' political and social engagement is required reading for anyone interested in likely Latino voting patterns in 2018 and beyond.
