Whether the form of the consecration of the bread accomplishes its effect before the form of the consecration of the wine be completed?

❌ Objection 1 : It seems that the form of the consecration of the bread does not accomplish its effect until the form for the consecration of the wine be completed. For, as Christ's body begins to be in this sacrament by the consecration of the bread, so does His blood come to be there by the consecration of the wine. If, then, the words for consecrating the bread were to produce their effect before the consecration of the wine, it would follow that Christ's body would be present in this sacrament without the blood, which is improper.

❌ Objection 2 : Further, one sacrament has one completion: hence although there be three immersions in Baptism, yet the first immersion does not produce its effect until the third be completed. But all this sacrament is one, as stated above (Question [73], Article [2]). Therefore the words whereby the bread is consecrated do not bring about their effect without the sacramental words whereby the wine is consecrated.

❌ Objection 3 : Further, there are several words in the form for consecrating the bread, the first of which do not secure their effect until the last be uttered, as stated above (Article [4], ad 3). Therefore, for the same reason, neither do the words for the consecration of Christ's body produce their effect, until the words for consecrating Christ's blood are spoken.
