The Catholic Church witnessed the emergence of numerous charisms during the 20th century, many of which bear an "original defect": allegations of abuse during their foundational period. While such origins do not necessarily invalidate these charisms, they require rigorous discernment regarding their problematic dimensions, as well as an art of care toward those affected and their religious experience. This recurring vulnerability also raises the question of whether such fragility is inherent to the conflictive and unstable nature of the founding stages of religious communities. This paper presents an interdisciplinary case study of a Pallottine priest involved in the foundation of the Schoenstatt Movement in Chile. The first part analyzes archival documents from 1956 to 1961—reports and correspondence uncovered through recent research—which reveal a progressive process of manipulation, alongside practices sanctioned at the time. Through a historical approach, the study reconstructs an evolutionary profile of the priest and examines how the Society of the Catholic Apostolate managed the case, situating it within the structural fragility typical of foundational periods. The second part explores contemporary interpretations of this "primal wound." Using ethnographic methods, particularly participant observation, it analyzes how current members of the community interpret and categorize these past events today. The research is guided by Ars Vulnerum—the art of tending to wounds—a methodological and ethical approach that seeks to engage responsibly with traumatic histories. Its aim is to work alongside the community, offering historical findings with accuracy, respect, and care, so that they may contribute not to the erosion of faith, but to its critical enrichment and repair.
