CHALICE (through a central O. Fr. form of the Lat. calix, calicis, cup), a drinking-vessel of the cup or goblet form, now only used of the cup used in the celebration of the Eucharist (q.v.). For the various forms which the "chalice" so used has taken, see Drinking-Vessels and Plate. When, in the eucharistic service, water is mixed with the wine, the "chalice" is known as the "mixed chalice." This has been customary both in the Eastern and Western Churches from early times. The Armenian Church does not use the "mixed chalice." It was used in the English Church before the Reformation. According to the present law of the English Church, the mixing of the water with wine is lawful, if this is not done as part of or during the services, i.e. if it is not done ceremonially (Martin v. Mackonochie, 1868, L.R. 2 P.C. 365; Read v. Bp. of Lincoln, 1892, A C. 664).
