CARDINALS AND CONSISTORIES
The pope alone decides who will be made a cardinal. Any priest can be named to the college, and all new members receive a formal document, called a biglietto (literally “ticket”) informing them of the honor. They are then enrolled formally into the Sacred College through an elaborate ceremony in Rome called a consistory.
The number of cardinals has varied considerably over the centuries. During the Middle Ages, it was not unusual for there to be a mere handful; at one point there were only four choosing a new pope. Pope Sixtus V (r. 1585-1590) decreed that there should be 70 members, a number that was unchanged until 1958, when Pope Blessed, John XXIII increased it by five. That number grew steadily, so that today there are around 180. By papal decree, no more than 120 are eligible to vote in a conclave to elect a new pope, although it has been set aside a few times, especially during the reign of Pope John Paul II. At the age of 80, cardinals lose the right to take part in any papal election, but their counsel is still prized by the pope.
SYMBOLS OF THE CARDINALS
Most people think that cardinals wear red. Cardinals actually wear scarlet, a custom that began in a formal sense in 1245 when Pope Innocent IV bestowed the famed red hat upon the cardinals. Scarlet reminds the cardinals that they must be willing to give of themselves for the Church, even to the point of shedding their blood.
New cardinals receive several symbols of their new title: a zucchetto, a biretta and a ring. A scarlet zucchetto (or skullcap) and scarlet biretta (a four-cornered silk hat) are both placed upon the cardinals’ heads by the hand of the pope. The ring is a symbol of a cardinal’s dignity, pastoral zeal and communion with the See of Peter.
THE CARDINALS’ OATH
Below is a translation of the oath of fidelity and obedience to the pope and his successors, pronounced by the cardinals at the time they receive the biretta, or cardinal’s hat:
I [name and surname], Cardinal of the Holy Roman Church, promise and swear to be faithful henceforth and forever, while I live, to Christ and His Gospel, being constantly obedient to the Holy Roman Apostolic Church, to Blessed Peter in the person of the Supreme Pontiff [current pope’s name], and of his canonically elected Successors; to maintain communion with the Catholic Church always, in word and deed; not to reveal to anyone what is confided to me in secret, nor to divulge what may bring harm or dishonor to Holy Church; to carry out with great diligence and faithfulness those tasks to which I am called by my service to the Church, in accord with the norms of the law.
So help me Almighty God.
