While the vast majority of Latinos are Roman Catholic, great numbers are leaving the fold. Many "defect" to Protestantism, especially Pentecostalism. This is true both in the United States and in Latin America as a whole. There are a number of reasons for this, but it does point out important areas of concern for all of us. It is not movement from one tradition to another that is the biggest concern -- it is secularism and even more worrisome, indifference. I invite you to read and respond to Martin Marty's thoughts.
