Lord's Supper, because this usage has the commandment of the
Lord in Matt. 26, 27: Drink ye all of it, where Christ has
manifestly commanded concerning the cup that all should drink.

And lest any man should craftily say that this refers only to
priests, Paul in 1 Cor. 11,27 recites an example from which it
appears that the whole congregation did use both kinds. And
this usage has long remained in the Church, nor is it known
when, or by whose authority, it was changed; although Cardinal
Cusanus mentions the time when it was approved. Cyprian in
some places testifies that the blood was given to the people.
The same is testified by Jerome, who says: The priests
administer the Eucharist, and distribute the blood of Christ
to the people. Indeed, Pope Gelasius commands that the
Sacrament be not divided (dist. II., De Consecratione, cap.
Comperimus). Only custom, not so ancient, has it otherwise.
But it is evident that any custom introduced against the
commandments of God is not to be allowed, as the Canons
witness (dist. III., cap. Veritate, and the following
chapters). But this custom has been received, not only against
the Scripture, but also against the old Canons and the example
of the Church. Therefore, if any preferred to use both kinds
of the Sacrament, they ought not to have been compelled with
offense to their consciences to do otherwise. And because the
division of the Sacrament does not agree with the ordinance of
Christ, we are accustomed to omit the procession, which
hitherto has been in use.
