Whether the Eucharist is one sacrament or several?
Objections
❌ Objection 1 : It seems that the Eucharist is not one sacrament but several, because it is said in the Collect [*Postcommunion "pro vivis et defunctis"]: "May the sacraments which we have received purify us, O Lord": and this is said on account of our receiving the Eucharist. Consequently the Eucharist is not one sacrament but several.
❌ Objection 2 : Further, it is impossible for genera to be multiplied without the species being multiplied: thus it is impossible for one man to be many animals. But, as stated above (Question [60], Article [1]), sign is the genus of sacrament. Since, then, there are more signs than one, to wit, bread and wine, it seems to follow that here must be more sacraments than one.
❌ Objection 3 : Further, this sacrament is perfected in the consecration of the matter, as stated above (Article [1], ad 3). But in this sacrament there is a double consecration of the matter. Therefore, it is a twofold sacrament.
