[¶0] OF THE MATTER OF THIS SACRAMENT (EIGHT ARTICLES)

[¶1] We have now to consider the matter of this sacrament: and first of all as to its species; secondly, the change of the bread and wine into the body of Christ; thirdly, the manner in which Christ's body exists in this sacrament; fourthly, the accidents of bread and wine which continue in this sacrament.

[¶2] Under the first heading there are eight points for inquiry:

[¶3] (1) Whether bread and wine are the matter of this sacrament?

[¶4] (2) Whether a determinate quantity of the same is required for the matter of this sacrament?

[¶5] (3) Whether the matter of this sacrament is wheaten bread?

[¶6] (4) Whether it is unleavened or fermented bread?

[¶7] (5) Whether the matter of this sacrament is wine from the grape?

[¶8] (6) Whether water should be mixed with it?

[¶9] (7) Whether water is of necessity for this sacrament?

[¶10] (8) Of the quantity of the water added.
