Abstract
This paper deals with Bonaventure’s stand on the separability of accidents discussed within the framework of the theology of the Eucharist, in his Commentarium in Sententias, IV, d. 12, p. 1, a. 1, q. 1. Since an accident was traditionally defined as ens in alio, the existence of accidents apart from any subject in the Eucharist was considered philosophically challenging. The Franciscan theologian has been credited with having distinguished, for the first time (Bakker PJJM.

The status of Eucharistic accidents “sine subiecto”: An historical survey up to Thomas Aquinas and selected reactions. München: Akademie Verlag, 2013), between the relation of accident to subject secundum aptitudinem, and the relation of accident to subject secundum actum, while sustaining that only the relation to subject secundum aptitudinem constitutes the accident’s proper definition, a view that Aquinas would subscribe to and develop further, relying on Avicenna’s idea of the real distinction between essence and existence. The chapter will discuss Bonaventure’s rather different reasons for refusing to accept actual being in alio as the accident’s essence. Bonaventure does not appeal to a distinction between being and essence but draws on the common essence of accidents in individualized substances vs. accidents as universals, or accidents secundum species sive differentias speciales.
