Religious Fragmentation, Social Disintegration? Social Networks and Evangelical Protestantism in Rural Andean Bolivia Marygold Walsh-Dilley 1 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Latin America remains, much more than any other region in the world, dominated by a single religion: Catholicism. But in the second half of the twentieth century, a so-called BProtestant wave^ spread across the region increasing religious diversity. This wave was spurred on by Pentecostal and other evangelical Protestant churches, denominations that challenge the religious syncretism, state-church relationships, and many of the institutions and relationships that structure social and cultural life in Latin America. These changes can bring tensions, conflicts, or abuses that can have a socially disintegrating effect. This paper uses Breligious fragmentation^ as a lens to examine this process in rural highland Bolivia. Drawing upon qualitative fieldwork in two communities, this paper first examines the motivations for and contestations surrounding increasing Protestant affiliation and second asks how religious fragmentation interacts with existing social networks and relationships. Paying special atten- tion to reciprocity networks, which are culturally and economically significant in these indigenous communities, this paper argues that non-religious social relationships and activities can act as intervening variables that overcome the social fragmentations of religious change.

Evangelicalism Introduction Latin America remains, much more than any other region in the world, dominated by a single religion: Catholicism (Latinobarómetro 2016). While the Catholic Church has had profound influence in Latin America from conquest through today, and continues to structure much of social and spiritual life, there has also been considerable diversity in popular Catholic Qualitative Sociology https://doi.org/10.1007/s11133-019-09425-z * Marygold Walsh-Dilley marygoldwd@unm.edu 1 Honors College, University of New Mexico, Albuquerque, NM 87131-0001, USA
