A prosphoron (Greek: πρόσφορον, translation: offering) is a small loaf of bread used in Orthodox Christian liturgies. The plural form is prosphora (πρόσφορα). The term originally meant any offering made to a temple, but in Orthodox Christianity has come to mean specifically the bread offered at the Divine Liturgy.

A prosphoron is made up of two separate round pieces of dough which are placed one on top of another and baked together to form a single loaf. This double-loaf represents the two natures of Christ: human and divine. Before baking, each prosphoron is stamped with a seal usually bearing the image of a cross with the Greek letters IC XC NIKA ("Jesus Christ Conquers") around the arms of the cross. This impression is baked into the bread and serves as a guide for the priest who will be cutting it.

Please be reminded to sign up on the parish bullitin board if you wish to offer prosphora in the memory of a loved one, on the occasion of an anniversary, or a birthday, or in general thankfulness for the many blessings recieved. Prosphora should best be delivered to the Church following Great Vespers Saturday evening , and if freshly baked, wrapped in a cloth accompanied with with a list of the Orthodox living and departed to be commemorated during the Liturgy.
