Liturgical arcanum et obscura: Cardinal Protodeacons, etc.

I was not aware of these distinctions. That's why I'm glad we have The New Liturgical Movement:

At this morning's Ordinary Public Consistory ... the Holy Father also elevated some Cardinals from the Order of Deacons to the Order of Priests...

Liturgically, this means we will not see these cardinals function as Cardinal Deacons in papal Masses, with dalmatics and mitres, anymore.

Since Cardinal Castrillón Hoyos was, until now, Cardinal Protodeacon (i.e. the first in the Order of Deacons), whose office it is to announce the name of the newly elected Supreme Pontiff (can. 355 § 2), this office had to be reassigned. The new Cardinal Protodeacon is His Eminence Agostino Cacciavillan, former Apostolic Pro-Nuncio to the United States and former President of the Administration of the Patrimony of the Apostolic See.
