Gottesdienst Online has a reference to http://puritycommunion.org/landing/. The topic is "Purity Communion." Bread & Wine wafers and sanitary dispensers prevent the spread of germs among the communicants.
The theologian J. S. Bach had this to say about Holy Communion (Was Gott tut daß ist wohl getan) "No poison can be in the cup that my Physician sends me."
Need I say more?
