This tradition lives on in other Eastern churches. Recently, in my Maronite Catholic parish, this type of bread was placed on a table in the sanctuary during the celebration of the mass to honor a long time parishioner who had recently passed away. It is the tradition of our church to celebrate a "40 day liturgy" on the 40th day following their burial. A large spread of food is prepared for the congregation and visitors, including this special bread.
For those of you who feel a tug toward learning more about the Coptic Church, I would strongly encourage you to read:
It is an amazing journey into the depth of faith held by our Coptic brethren, described by a Roman Catholic priest and monk, Fr. Mark Gruber, OSB.
