The paper examines how Orthodox communities of forcibly displaced Ukrainians in Germany organise worship and ecclesial life in the absence of permanent church buildings. These communities often depend on temporary and shared spatial arrangements, including the use of Catholic and Protestant churches, as well as non-sacral settings such as refugee shelters or a theatre. Approaching worship as a spatial practice, the paper treats the church not as a fixed place but as an event. It introduces the notion of a "church in a suitcase" to describe a mode of ecclesial presence in which minimal liturgical means are sufficient to transform borrowed spaces into places of worship and encounter. The paper also looks at how displacement shapes authority and community formation. While the formal establishment of a parish presupposes a collective request from an existing community, in practice priests often initiate and sustain these communities themselves by gathering parishioners, and maintaining relations with host confessions. As a result, responsibility for community life tends to rest with the clergy rather than with a stable congregation. By focusing on temporary spatial arrangements and everyday organisational practices, the paper offers an empirical perspective on emerging forms of Christian presence in contemporary urban contexts.
