3. I deem it well, however, that the Church in a general council should again decree[3] that all persons, as well as the priests, be given both kinds. Not that one kind were insufficient, since indeed the simple desire of faith suffices, as St. Augustine says: "Why preparest thou stomach and teeth? Only believe and thou hast already partaken of the sacrament";[4] but because it would be meet and right that the form, or sign, of the sacrament be given not in part only, but in its entirety, just as I have said of baptism[5] that it were more fitting to immerse than to pour the water, for the sake of the completeness and perfection of the sign. For this sacrament signifies the complete union and the undivided fellowship of the saints, as we shall see, and this is poorly and unfittingly indicated by only one part of the sacrament. Nor is there as great a danger in the use of the cup as is supposed, since the people seldom go to this sacrament, and Christ was well aware of all future dangers[6], and yet saw it to institute both kinds or the use of all His Christians. [Sidenote: The Second Part of the Sacrament: the Significance] 4. The significance or purpose of this sacrament is the fellowship of all saints, whence it derives its common name _synaxis_ or _communio_, that is, fellowship; and _communicare_ means to take part in this fellowship, or as we say, to go to the sacrament, because Christ and all saints are one spiritual body, just as the inhabitants of a city are one community and body, each citizen being a member of the other and a member of the entire city. All the saints, therefore, are members of Christ and of the Church, which is a spiritual and eternal city of God, and whoever is taken into this city is said to be received into the community of saints, and to be incorporated into Christ's spiritual body and made a member of Him. On the other hand, _excommunicare_ means to put out of the community and to sever a member from this body, and that is called in our language "putting one under the ban"; yet there is a difference, as I shall show in the following treatise, concerning the ban[4]. To receive the bread and wine of this sacrament, then, is nothing else than to receive a sure sign of this fellowship and incorporation with Christ and all saints. As though a citizen were given a sign, a document, or some other token as a proof that he is a citizen of the city, a member of the community. Even so St. Paul says: "We are all one bread and one body, for we are all partakers of one bread and of one cup." [1 Cor. 10:17]
