After taking Communion, at the end of the Divine Liturgy, and at Vespers with a “Litya” or “Blessing of Bread", it is traditional to eat a piece of holy bread or antidoron—the left-over bread from which Holy Communion was prepared and various commemorations made. While antidoron is not the Body and Blood of Christ, it is blessed bread, and as such, we should take precaution to eat it carefully so that crumbs don’t fall to be trampled underfoot. Monitor the children as they take the antidoron, teaching them to eat respectfully.
