This thesis discovers the figure of refugees as 'naked life' within specific cases of refugee, and discusses the possibility of cohabitation with refugees by confirming the 'Hospitality-polyhedron'. The study utilizes Agamben's concept of Homo sacer. This explores the possibility of cohabiting with 'refugees' who live in a exception of state as naked life, and deals with the issue of 'refugee camps' as a device of bio-politics. This thesis uses Agamben’s concept of Homo sacer as a critical methodology. While Agamben see the figure of refugees treated as naked life within Homo Sacer, this thesis critically applies this concept to the case of ‘Jeju Yemeni refugees’ as a contemporary example of refugees under the mechanism of bio-politics, and then re-examines it within the Magisterial teaching on refugees. After organizing the situations of 'civil war', 'exploitation', and 'detention centers' included in the case of ‘Jeju Yemeni refugee’ camp, this study apply it to the Church's teaching, such as the 'Pontifical Council for the Pastoral Care of Migrants and Itinerant People's Guidelines' and Fratelli Tutti. By discovering the characteristics of Agamben's basic concepts on refugees ('Common path', 'Neighbors without borders', and 'Hospitality-polyhedron') within Pope Francis's first social encyclical Fratelli Tutti, this study further clarifies the church's stance on the practice of the virtue of hospitality.
