Pure or Noble Materials for Jewish Ritual Vessels: Passover Meal and the First Eucharistic Chalice (Holy Grail)

Very little is known about the chalice used by Jesus of Nazareth at the Last Supper. The first Christians used a cup of blessing for the Eucharistic celebration (1Cor 10:16), which insinuates that Jesus used a ritual cup. An exegetical study of the synoptic gospels reveals that this ritual dinner was celebrated in the home of a wealthy disciple of Jesus, who would have lent him the most valuable cup of blessing owned by the family. Hence, it is unlikely that this cup was made of common and cheap materials, such as ceramic or wood. The only mention of this cup in the early centuries is due to St. John Chrysostom, who states (ca. 395 AD) that it was not made of silver. However, its veracity is not reliable due to the lack of earlier comments. In recent decades, archaeological excavations in the Holy Land have revealed that, at the time of Jesus, the use of vessels carved in limestone was common in Jerusalem for ritual practices in the domestic sphere because they were considered unsusceptible to impurity. This fact suggests that the chalice of the Last Supper might have been a valued cup of carved stone, which is consistent with the use of such bowls in the Hellenistic-Roman period among the aristocratic classes.
