Religious conviction has played a prominent role in many activist movements throughout the United States. In this article, I detail one social justice organization’s enactment of activism called la fe en acción (faith in action). This approach was nuanced from being simply “activism” but one that, according to participants, was more strategic and longer lasting. La fe en acción served as the central strategy utilized by this organization in order to garner public and political support for comprehensive immigration reform. A crucial component within this approach included the sharing of testimonios (testimonials) of participants. While this form of activism was intended to garner the participation of all people—including undocumented immigrants—for some, structural vulnerability hindered their ability to participate. Overall, I explore the positive and negative aspects of this approach as elaborated from data gathered during attempts to garner support for comprehensive immigration reform in 2013.
