Eucharistic elements

The sensible matter of the Sacrament of the Holy Eucharist, over which are pronounced the words of consecration. These are bread and wine mixed with a little water. The bread must be purely of wheaten flour and recently made. The wine must be the natural juice of the grape vine and uncorrupted. In the Latin rite, the bread is unleavened, i.e., without yeast; in the Eastern rites it is leavened.
