The EF Mass, as in all things, has very strict rubrics about the ablutions. No so the OF Mass, not so.
Because of the proliferation of chalices due to the common chalice offered to numerous communicants and from the same chalice, there are more chalices to be cleansed after Holy Communion from two to 12, if not more, depending on the parish community.
Every parish I have served has had the common chalice. Because there are so many chalices to be cleansed the practice has been for the extraordinary ministers to consume what remains of the Precious Blood and place the chalice on the credence table with the purificator on top of it.
After Mass an instituted acolyte or deacon (or in their absence) an extraordinary minister does the ablutions in the sacristy. After the first ablution, the chalices are then washed with soap and hot water due to the number of communicants drinking from the same chalice.
This has been the practice at my current parish too. For daily Mass, though, we have two additional chalices for the laity. My biggest phobia with the common chalice isn't so much drinking after someone who precedes me, but doing the ablutions on all the chalices and drinking the dregs as well as the water place into the chalice. I personally find it disgusting and I offer up my sacrifice of doing so for the poor souls in purgatory.
What I do to cut down on germs to me is to place a great deal of water in the first chalice and then transfer it to the other chalice and finally to my chalice and then drink it from it.
I am convinced that I have chronic colds and sinus issues due to the infinite number of germs and bacteria I consume in my daily sacrifice.
With the laity drinking the ablutions and cleansing the chalices after Mass in the sacristy, one never knows if what exists of the Precious Blood is profaned or irreverence is shown in the sacristy while cleansing the chalices, through useless chatter and laughing.
Because of the public health crisis concerning the epidemic of the flu spreading in Georgia and elsewhere, St. Anne's has discontinued the use of the common chalice for public health reasons.
Not only has it made the distribution of Holy Communion in line with Vatican II's desire for noble simplicity, now I do the ablutions for my chalice at the altar after Holy Communion and redress the chalice as in day of old.
And I am not worried by the constant exposure to viruses and bacterial infections I experience in drinking the ablutions at daily Mass.
What I worry about are all the waiting poor souls in purgatory that will not benefit any longer from my sacrifice of ablutions at daily Mass.
