When I first started as an altar boy, I had to learn the Latin prayers. My 'captain' told me that until I learned the Latin, I could say "Sack of Potatoes, sack of peas" and it would sound OK. One Mass when the captain was not there and it was myself and another rookie at Mass. During the Confiteor, there we were, "Sack of Potatoes, sack of peas" when suddenly the priest stopped. The horror! He didn't have to say anything. We learned the prayers quickly.
Monsignor Pope Ping!
In my Orthodox parish, a helper (usually acolyte or adult man from the congregation) holds a napkin between the chalice and the communicant to catch any particles of the Body and Blood that might fall from the spoon. The napkins are specially cleaned later. I suppose that is like the chin paten.
I surely miss Pope Benedict!
I remember holding the paten when I was an alter boy and that after communion we placed the paten on the altar so the priest could carefully wipe any particles of the Eucharist into the chalice before we could return it to the side table. That reverence is long gone.
