a cup used in the celebration of the Christian Eucharist. Both the statement of St. Paul about "the cup of blessing which we bless" (1 Corinthians 10:16) and the accounts of the institution of the Eucharist in the first three Gospels indicate that special rites of consecration attended the use of the chalice from the beginning. It was not until the recognition of Christianity by the Roman Empire in the 4th century that silver and gold became the usual materials for the chalice. In the Middle Ages the legend of the Holy Grail surrounded the origins of the eucharistic chalice with a magical aura.
