I was once told a joke about an English engineer, who shows a French engineer the plans of a machine he intends to build. The English engineer asks the French engineer: “Do you think this will work?” The French engineer responds: “Of course it will work in practice, but will it work in theory?” This is exactly the question I would like to ask. Of course, the way we read the city space where spiritualities interact seems to work in practice, but does it work in theory? I believe that the transformation and liberation of mission is crucial in the face of the rise of this new city space, given that this is where most of the world's population already lives (Sheldrake, 2010: 159) . liberating mission, I suggest looking at the way we read the space of the city where spiritualities interact. Recently, the interdisciplinary journal Culture and Religion (2012) published a special edition on the theme: Believing in the city: urban cultures, religion and (im)materiality. Each of the urban spiritualities described in the journal believed to transform or liberate the city in one way or another. At the basis of the urban spiritualities described in this edition of Culture and Religion was the metaphor of a battle for city space. By publicly living their spirituality, each group believed they were reclaiming secular space as spiritual space or reclaiming spiritual space from an opposing spirituality. The city has thus become the site of a zero-sum space game in which spiritualities can clash. A zero-sum game is a game in which there is only one winner and one loser (Von Neumann & Morgenstern, 2007: 46-47). .A zero-sum reading of the space of urban spiritualities reduces this space to ...... middle of paper ...... a manifesto.
