Christianity is thus defined by its ability to capture narrative through normative order, while animating it with the perpetual movement of gloss, creating the conditions for a never-ending event. But what is its figura, that "sketch of fiction" that shapes, invents, represents and feigns society all at once? The hypothesis here is that it is the Eucharistic mystery that configures society as a whole, or is, to use Hans Blumenberg's terminology, its rector metaphor. But it is the Eucharist in the sense that the Gregorian reform transformed it, from the moment the Church took the turn towards the Eucharistic realism of transubstantiation. Here, we recall the major historical stages, the theoretical cost and the political significance of such a decision, which runs counter to the Augustinian theory of the sign. The coup de force of the real presence has consequences for the architecture of the ecclesiastical edifice and the ecclesiastical institution. But it is also difficult to believe: this is why the lecture ends with a discussion of the unbelievers of the real presence, who resist this orthodoxy of the unbelievable, as revealed by famous cases documented by judicial sources.
