The aim of this paper is to reveal how the narration of the forms of ‘personal’ sacrilege and its consequences in Estormi, Les Quatre prestres, the three versions of Le Sacristain, Le Chapelain and Le Prestre comporté makes it possible to ‘think without concepts’ (Florence Goyet) about the way in which the Church incarnates itself in order to become involved in the organisation of earthly society. Indeed, these texts not only reflect, in a specular movement (always debatable...) but also reflect on, through an intellectual - albeit playful - operation, the possible drifts of this incarnation. What's more, through the attacks committed by the corpus temporale on the corpus spirituale that they portray, these stories go so far as to destabilise the ways in which the corporeal and the spiritual are articulated. They definitively inscribe in the register of the caro what and those who, in the all-encompassing framework of the medieval system of representations, nevertheless belong to the spiritus.
