Shut Up, He Explained

Huh? From the New Liturgical Movement:

Translation of the Italian:
 

The fourth Sunday of Lent, John XXIII was once again among the crowd, at Ostia. (about 15 miles to the south-west of Rome.) Thousands of people were waiting for him along the street, in the piazza, in the church. They wanted to see him, to applaud him. They did not know that afterwards, he would rebuke them, in a good-natured way, in his simple , spontaneous, familiar way of speaking.
“I am very glad to have come here. But if I must express a wish, it is that in church you not shout out, that you not clap your hands, and that you not greet even the Pope, because ‘templum Dei, templum Dei.’ (‘The temple of God is the temple of God.’)
Now, if you are pleased to be in this beautiful church, you must know that the Pope is also pleased to see his children. But as soon as he sees his good children, he certainly does not clap his hands in their faces. And the one who stands before you is the Successor of St. Peter.”
