The third question and answer is quite blunt:
To make the Mass attractive and joyful to the youth of this culture of the image, there have been initiatives such as the "Disco Mass", and dances of erotic origin were seen in Africa. Is [the 1962 Missal] a solution [original text: "remedio"] to stop these abuses?
It is an element, not "the solution". The new liturgy has not been "the solution". Were our churches fuller or emptier before? They have been emptied! It is true that not only due to this, but the Mass becomes one among several other rites of the world, and to strike what is sacred is a grave matter. The meaning of "Sacrifice" was forgotten. The Eucharist carries [us] to the Resurrection, but through Passion and Death. It is a feast of the spirit, for our redemption. The most important for Jesus was not eating with Him, but eating Him.
