Whether this is the proper form for the consecration of the bread: "This is My body"?

❌ Objection 1 : It seems that this is not the proper form of this sacrament: "This is My body." For the effect of a sacrament ought to be expressed in its form. But the effect of the consecration of the bread is the change of the substance of the bread into the body of Christ, and this is better expressed by the word "becomes" than by "is." Therefore, in the form of the consecration we ought to say: "This becomes My body."

❌ Objection 2 : Further, Ambrose says (De Sacram. iv), "Christ's words consecrate this sacrament. What word of Christ? This word, whereby all things are made. The Lord commanded, and the heavens and earth were made. " Therefore, it would be a more proper form of this sacrament if the imperative mood were employed, so as to say: "Be this My body."

❌ Objection 3 : Further, that which is changed is implied in the subject of this phrase, just as the term of the change is implied in the predicate. But just as that into which the change is made is something determinate, for the change is into nothing else but the body of Christ, so also that which is converted is determinate, since only bread is converted into the body of Christ. Therefore, as a noun is inserted on the part of the predicate, so also should a noun be inserted in the subject, so that it be said: "This bread is My body."

❌ Objection 4 : Further, just as the term of the change is determinate in nature, because it is a body, so also is it determinate in person. Consequently, in order to determine the person, it ought to be said: "This is the body of Christ."

❌ Objection 5 : Further, nothing ought to be inserted in the form except what is substantial to it. Consequently, the conjunction "for" is improperly added in some books, since it does not belong to the substance of the form.
