The cup of the Lord is not water only, or wine only, but the two are mixed; so the Lord’s Body cannot be either flour only, or water only, but the two are combined.
[ed. note: To signify, as S. Cyprian proceeds to say, the union between Christ and His faithful people; “For if one offer wine only, the blood of Christ begins to be without us; if water only, the people begin to be without Christ.” This passage of Cyprian is quoted in Gratian. de Cons ii. 7.]
