The first time I ever entered the Vatican Basilica was on March 19, 1998 for the episcopal consecration of Mons. Piero Marini. Sad was I to see how common the liturgy was.
The first time I ever shared an afternoon with Cardinal Ratzinger was on March 20, 2004. He gave a lecture at the Pontfical Oriental Institute where he shared with us that he was first in the Vatican Basilica for Easter of 1962 back in the day with the splendor of the old papal liturgies.
Why did Piero Marini so get it wrong? The story in Rome is that his whole liturgical modus operandi was always just leges nullae (liturgical lawlessness). Even in Leviticus X the Lord Himself speaks to Aron the priest and says: "You are to distinguish between the holy and the common."
