Unleavened bread

Host and communion wafers made of azymes for celebrating the Eucharist in the Latin Church of the Catholic Church and other Western Christians (Eastern Christians such as the Eastern Orthodox use leavened bread).

Unleavened breads have symbolic importance in Judaism and Christianity. Jews and Christians consume unleavened breads such as matzo during Passover and Eucharist, respectively, as commanded in Exodus 12:18. Per the Torah Old Testament, the newly emancipated Israelites had to leave Egypt in such a hurry that they could not spare time for their breads to rise; as a reminder of that, unleavened bread is used in ceremonies.

Canon Law of the Latin Church within the Catholic Church mandates the use of unleavened bread for the Host, and unleavened wafers for the communion of the faithful. Some Protestant churches tend to follow the Latin Catholic practice, whereas others use either unleavened bread or wafers or ordinary (leavened) bread, depending on the traditions of their particular denomination or local usage.

On the other hand, most Eastern Churches explicitly forbid the use of unleavened bread (Greek: azymos artos) for the Eucharist. Eastern Christians associate unleavened bread with the Old Testament and allow only for bread with yeast, as a symbol of the New Covenant in Christ's blood. Indeed, this usage figures as one of the three points of contention that traditionally accounted as causes (along with the issues of Petrine supremacy and the filioque in the Niceno-Constantinopolitan Creed) of the Great Schism of 1054 between Eastern and Western churches.[1]
