1. First Conclusion and its Proof

357. And let the first conclusion be that Christ in the Eucharist cannot use any bodily active power, whether it be merely bodily (namely what follows the nature of this sort of mixed body) or bodily in the sense of following first or immediately the animate whole.

358. The proof is briefly that all bodily active powers require that the passive object, on which they act, be close to them in location. These powers, as they are here [sc. in Christ’s body in the Eucharist] are not anywhere by location; therefore they cannot, as they are here, have a passive subject close to them in the way required for the action of such powers. The major proposition is plain from Physics 7.1.242b24-26, where it is proved that a bodily agent must be close to the passive subject, whether mediately or immediately.
