The Eucharist is the Christian sacrament of bread and wine. The Chalice of the Eucharist is the cup out of which the wine is drunk.

Traditionally, Jesus drunk out of the chalice at The Last Supper. Joseph of Arimathea then collected Jesus' blood when he was crucified. This belief comes from the 3 synoptic gospels; Matthew, Mark and Luke. These 3 gospels as well as Paul's first letter to the Corinthians also contained the "Words of Institution", supposedly spoken by Jesus at the Last Supper: "Take, eat, this is my body.... Take, drink, this is my blood.... Do this in remembrance of me." As a result, Christians drink wine out of a chalice (representing Christ's blood) as part of the Eucharist.

The term is used within Lutheran, Roman Catholic, Anglican and Eastern Orthodox traditions. The practice is also known as Communion. It originates from the Greek eucharisto meaning to give thanks or to rejoice. The Chalice of the Eucharist is often linked with legends of The Holy Grail and Joseph of Arimathea
