Reply to Objection 3. As Pope Innocent says in the aforesaid Decretal, “if after the consecration other wine be put in the chalice, it is not changed into the blood, nor is it mingled with the blood, but, mixed with the accidents of the previous wine, it is diffused throughout the body which underlies them, yet without wetting what surrounds it.” Now this is to be understood when there is not sufficient mixing of extraneous liquid to cause the blood of Christ to cease to be under the whole; because a thing is said to be “diffused throughout,” not because it touches the body of Christ according to its proper dimensions, but according to the sacramental dimensions, under which it is contained. Now it is not the same with holy water, because the blessing works no change in the substance of the water, as the consecration of the wine does.
