 The portion which remains in the chalice afterwards must be consumed.The ablutions will normally be performed by the deacon, but if no deacon is serving the priest will do them.After the Litany of Thanksgiving that follows Communion, the deacon will come into the sanctuary and kneel, placing his forehead on the Holy Table (Altar) and the priest will bless him to consume the Gifts, which is done at the Prothesis (Table of Oblation).
