chalice
The cup-shaped vessel or goblet used at Mass to contain the Precious
Blood of Christ. For centuries it was made of precious material; if it
was not of gold, the interior of the cup was gold-plated. Since the
Second Vatican Council, chalices may be of other materials. A chalice is
consecrated with holy chrism by a bishop. Regilding the inside does not
destroy the consecration. sometimes the word chalice designates its
contents. (Etym. Latin calix, cup, goblet, drinking vessel, chalice.)
