Whether water should be mixed with the wine?

❌ Objection 1 : It seems that water ought not to be mixed with the wine, since Christ's sacrifice was foreshadowed by that of Melchisedech, who (Gn. 14:18) is related to have offered up bread and wine only. Consequently it seems that water should not be added in this sacrament.

❌ Objection 2 : Further, the various sacraments have their respective matters. But water is the matter of Baptism. Therefore it should not be employed as the matter of this sacrament.

❌ Objection 3 : Further, bread and wine are the matter of this sacrament. But nothing is added to the bread. Therefore neither should anything be added to the wine.
