Cardinal (Catholic Church)

Roles and responsibilities

Cardinals carry several overlapping functions. They act as principal counselors to the pope and often lead major dioceses or head departments of the Roman Curia. When the papacy becomes vacant, cardinals under the age of eighty at the time of the vacancy gather in a conclave to elect a new pope. Outside of a conclave, the College meets periodically to discuss matters concerning the universal church.

Ranks, vesture and titles

Within the college there are traditional ranks commonly referred to as cardinal-bishops, cardinal-priests, and cardinal-deacons. These distinctions reflect historical origins and different liturgical or administrative roles. Cardinals are well known for their red attire: a red biretta, cassock, and sometimes a red hat. The color is a symbol of their willingness to defend the faith, even to the shedding of blood.

History and development

The office evolved from clergy attached to Rome’s principal churches and from senior officials who aided the pope. Over centuries the cardinalate became a central instrument for papal governance and episcopal promotion. The custom of assigning a red hat to cardinals was confirmed in the 13th century; historically, Pope Innocent IV granted the use of the red hat in 1245, a gesture that reinforced the symbolic meaning of the color. The institution has adapted its numbers, procedures and eligibility rules in successive reforms.

Selection, eligibility and modern practice

The pope alone names cardinals, usually by publishing a list in a consistory. While most cardinals are bishops, the pope may dispense from episcopal ordination in exceptional cases. A cardinal who is under eighty at the moment the papacy becomes vacant is eligible to vote in the conclave; this age limit and the total number of electors have been regulated by recent popes to maintain practical conclave size and representation.

Significance and notable facts
