Chile has undergone an accelerated process of religious transformation, marked by a decline in Catholic affiliation alongside the persistent vitality of popular religious practices, the consolidation and stability of evangelical pluralism, and a growing proportion of individuals who do not declare a religious affiliation, particularly among younger cohorts. Drawing on empirical observation of intergenerational religious transmission within families in Chile, this presentation proposes to interpret these changes through the paradigm of pluralism (Berger, 2016). Pluralism generates two effects: on the one hand, it undermines the plausibility of religion; on the other, it may underpin a certain form of religious vitality by expanding the range of socially available religious alternatives. Based on qualitative fieldwork with multiple generations of families whose members display high levels of religious involvement, as well as with participants in popular religious festivals, I argue that intergenerational religious transmission entails the maintenance and production of a plausibility structure. This structure underpins mechanisms that can be interpreted through two ideal types. The first, which I term countercultural-elective, characterizes religious groups in tension with the surrounding social world, such as certain evangelical denominations and Catholic congregations, where threatened plausibility is actively produced within sub-societies capable of sustaining the objectivity of religion. This is combined with an emphasis on autonomy and the formation of an internal "market" of religious alternatives within a coherent religious world. The second type, which I call inherited cultural, presupposes a degree of contextual religious unanimity and therefore enters into crisis under contemporary conditions, primarily affecting traditional Catholicism.
