[quote=Brendan]Dr. C is right.
Both the GIRM and the US Norms on the Eucharist specify that any remaining Hosts not being reserved are to be consumed by the priest and deacon, if necessary with the assistance of EMHC’s.
Now certain circumstances is the Blessed Sacrament allowed to be buried.
Each church has a special sink, called a* sacrarium *that leads directly undergrount, NOT to the sewer system.
to clean calices, ciboria and purificators, they are first rinsed and the rinse water poured into the sacrarium. By definition, the rinse water would carry the Blessed Sacrament, and thus it is commited to holy ground.
While it is the norm for cleaning Precious vessels, it should NOT be the norm for the Blessed Sacrament as a whole.
Blessed items, such as broken rosaries, palm branches from Palm Sunday ect… are also to be either burned or commited to the ground, NEVER thrown in the garbage.
The first rinse water is always consummed. The ciborum is never used as a cup. Water is placed in it and circulated then poured into a chalice to be consummed. The second rinse water can be poured down the sacrarium.
This is why the GIRM requires that the priest or deacon be the one purifiying the vessels who can be ASSISTED by an EMHC if necessary. It also requires that the remaining Precious Blood be consummed in the open, at the altar, under the supervision of the priest or deacon. The vessels can then be placed if necessary on a table for further purification by the priest or deacon later.
