Marriage is an institution known for both its virtues and challenges. This study examines marriage not merely as a sociological or theological construct but as a lens to explore the profound philosophical problems of intersubjectivity and interpersonality. By examining both the relational and sacramental dimensions of marriage, we gain insights into how two distinct individuals can form a deep, enduring bond that transcends individual isolation, thus offering a model for understanding both intersubjectivity and interpersonality. The unique perspective offered by Christian (...) theology, which regards marriage as a sacrament, entails a fundamental and irreversible transformation in the individuals involved. This provides a unique venue to address intersubjectivity and interpersonality using unconventional sources and analysis. The objective is not to advocate for Catholic doctrine or any specific religious perspective but to deploy the sacramental understanding of matrimony and its conceptual framework to address these intertwined philosophical issues.
