Whether the sacramental species are broken in this sacrament?

Objections

Objection 1 : It seems that the sacramental species are not broken in this sacrament, because the Philosopher says in Meteor. iv that bodies are breakable owing to a certain disposition of the pores; a thing which cannot be attributed to the sacramental species. Therefore the sacramental species cannot be broken.
Objection 2 : Further, breaking is followed by sound. But the sacramental species emit no sound: because the Philosopher says (De Anima ii), that what emits sound is a hard body, having a smooth surface. Therefore the sacramental species are not broken.
Objection 3 : Further, breaking and mastication are seemingly of the same object. But it is Christ's true body that is eaten, according to Jn. 6:57: "He that eateth My flesh, and drinketh My blood." Therefore it is Christ's body that is broken and masticated: and hence it is said in the confession of Berengarius: "I agree with the Holy Catholic Church, and with heart and lips I profess, that the bread and wine which are placed on the altar, are the true body and blood of Christ after consecration, and are truly handled and broken by the priest's hands, broken and crushed by the teeth of believers." Consequently, the breaking ought not to be ascribed to the sacramental species.
