Some Christians call the bread used for Communion, especially when wafers are used, the host.
An interesting convergence of words, host means two different things for us in the Eucharist, with different roots. Originally, the word host came from the Middle English (14th century) word hoste, (oste or hoiste), which was the translation of the Latin word for sacrifice or victim. (This is the root of the English word, hostile.) Calling the bread, the “host,” reminds us that Christ suffered and died for us to receive the meal.
But we also remember that Christ is the host of the meal we share. He serves us, and we receive from him. This meaning of the word host comes from the Middle English (14th century) word hoste, which is related to the root word in Latin, hospit-, hospes, (as in hotel, hostel, or hospital).
