In an interview to Italian religious news website Petrus, the Archbishop of Lima, Peru, Cardinal Cipriani Thorne, had a very interesting answer to one of the questions:
We turn then to the manner of administering Communion...
[Cipriani Thorne] "Even in this case, the 'laxity' of many priests has ridiculed the value of the Eucharist in the eyes of Catholics. I personally believe that the best way to administer Communion is on the tongue, so much so that in my Diocese I have forbidden [vietato] particles in the hands. In the Masses with an enormous attendance [of faithful], we have found in the past lost particles on the floor of the church."
