This research aimed to generate more complex knowledge regarding youth religiosity in Santiago de Chile. Following Van der Ven’s proposal, an empirical-theological study was developed, guided by three main questions: How is youth religiosity in Santiago today configured? What personal and social factors influence it? And what contributions does this knowledge bring to theological and pastoral reflection? Using a Mixed Method (qual-QUAN) five dimensions were explored: beliefs, events of contact, practices, consequences in daily life, and groups of reference. The results were a valuable contribution to the available knowledge and theological reflection in dialogue with "lived religion".
