When I first read your suggestion, Gorgias, I thought it was a good idea.
Well, I’m not sure it’s a
good idea; more like a thought experiment…
Surely the first rinsing with water has to be drunk. to avoid any Precious Blood going down the sink?
No, on two accounts. First of all, it would never go “down the sink” (although the sacrarium would be OK, but in this case I’m thinking a large enough quantity of water that you wouldn’t want to pour it down the sacrarium).
Second, picture the few drops left in the bottom of a glass. (OK… many glasses.) Then picture the glasses in a large container (a pot, or whatever), and the pot filled with water. There would be no discernible accidents of wine in that pot,
and therefore, the Eucharist would no longer be present. So, in a very literal way, there’s no “Precious Blood” going anywhere. Out of respect to the sacrament that
had been present, though, I’d think that you’d want to pour the water directly to ground.
Again, this isn’t a discussion of
purification, per se.
