The word cardinal derives from the Latin term cardo, meaning hinge or pivot, a linguistic root that reveals the office's original function as the essential support upon which the Church turned. In the early sixth century, the first individuals to bear this title were not the powerful political figures of later centuries, but the deacons of the seven regions of Rome, tasked with administering the city's charitable works and liturgical duties. By the eighth century, these Roman clergy had evolved into a privileged class, taking part in the administration of the Church and the papal liturgy, eventually securing the right to elect the Bishop of Rome through a synod of 769. The term spread beyond Rome to designate senior priests in other cities, yet it was Pope Pius V who, in 1567, reserved the title exclusively for the cardinals of Rome, transforming a general honorific into a specific rank of the highest order. This historical evolution from local administrators to the principal advisors of the Pope established the College of Cardinals as the central engine of the Catholic Church, a body that would eventually wield power far exceeding its ecclesiastical origins.
The Red Hat And The Blood
The visual identity of a cardinal is defined by the scarlet red of their garments, a color chosen to symbolize their willingness to shed blood for the faith, a tradition that dates back to the granting of the red hat, or galero, by Pope Innocent IV in 1244. This distinctive wide-brimmed hat, once a standard part of a cardinal's attire, was discontinued as a physical garment in 1969, yet it remains a permanent fixture in ecclesiastical heraldry, displayed on the coat of arms with fifteen tassels on each side to denote the cardinal's rank. The red color extends to the biretta, the square cap worn by cardinals, which lacks the tassel found on the hats of other prelates, and to the mozzetta, a short cape worn over the cassock. While the physical hat is gone, the symbolism of the red color persists in the daily life of the Church, where cardinals wear scarlet cassocks with scarlet piping and sashes, creating a visual uniform that distinguishes them from all other clergy. The tradition of the red hat also gave rise to the common name for the bird, the cardinal, a connection that underscores the deep cultural imprint of the office on the wider world.
The Electors And The Eighty
The most solemn responsibility of the College of Cardinals is to gather in a conclave to elect a new pope, a process that has evolved from a chaotic struggle among Roman nobles to a tightly regulated election governed by strict age limits. In 1059, Pope Nicholas II granted cardinals the right to elect the Bishop of Rome, a power that was initially restricted to cardinal bishops before being restored to the entire body of cardinals by the Third Lateran Council in 1179. The modern rules of the conclave were significantly shaped by Pope Paul VI, who in 1970 established that only cardinals under the age of 80 could participate in the election of a successor. This rule, which took effect on the 1st of January 1971, immediately deprived 25 cardinals of their voting rights, ensuring that the College remained a body of active, working-age leaders. The number of electors has been capped at 120, though Popes have frequently exceeded this limit, with Pope Francis reaching as high as 140 in his consistory of December 2024, leading to a conclave with 133 participating cardinals. The age limit serves as a mechanism to ensure that the election is conducted by those who are likely to serve the Church for a significant period, preventing the College from becoming a relic of the past.
Throughout history, the office of cardinal has been inextricably linked to secular power, with some cardinals wielding influence that rivaled or even surpassed that of monarchs. Cardinal Richelieu, the chief minister of France in the early 17th century, effectively ruled the country, and his successor, Cardinal Mazarin, continued this tradition of political dominance. In England, Cardinal Wolsey served as the chief minister to King Henry VIII, while in Portugal, Cardinal Henry of Portugal was crowned king, the only example of a cardinal-king in history. These figures, known as crown cardinals, were often nominated by monarchs to represent their interests within the Church, a practice that led to the development of traditions entitling certain kings, such as those of Austria, Spain, and France, to nominate a trusted clerical subject. The political power of cardinals was so great that they could influence the outcome of wars and the succession of thrones, turning the Church into a major player in the geopolitical landscape of Europe. The history of the cardinalate is thus not merely a religious narrative but a chronicle of the intersection between spiritual authority and temporal power, where the red hat often served as a crown in all but name.
The Three Orders And The Hierarchy
The College of Cardinals is divided into three distinct orders, each with its own history, responsibilities, and place in the hierarchy of the Church. The senior order, cardinal bishops, originally consisted of seven bishops presiding over the suburbicarian sees around Rome, but today includes only six Latin Church cardinal bishops of the suburbicarian sees and patriarchs of the Eastern Catholic Churches. The largest order, cardinal priests, comprises the majority of cardinals, who are typically bishops of important dioceses around the world or officials of the Roman Curia, and who are assigned a titular church in Rome. The lowest order, cardinal deacons, consists mainly of officials of the Roman Curia and priests elevated after their 80th birthday, chosen primarily for the honor of the appointment since they cannot vote in a conclave. The transition between these orders is governed by specific rules, with cardinal deacons able to opt for the order of cardinal priests after ten years, and cardinal priests able to rise to the order of cardinal bishops, though the latter is now the sole prerogative of the pope. The Dean of the College, currently Giovanni Battista Re, is elected by the Latin Church cardinal bishops, while the Vice-Dean, Leonardo Sandri, is similarly chosen, ensuring a structured leadership within the College.
The Secret And The Living
Beyond the public cardinals who are named in consistory, the pope has the power to create secret cardinals, known as cardinals in pectore, whose identities are known only to the pontiff and who may never be revealed. This practice, which began with Pope Martin V, was used to protect cardinals from political persecution or other dangers, allowing the pope to ensure that a specific individual could be elevated to the College without exposing them to harm. The last pope known to have named a cardinal in pectore was Pope John Paul II, who named four such cardinals, one of whom remains unidentified to this day. If a pope dies before revealing the identity of a secret cardinal, the appointment expires, and the individual does not become a cardinal. This mechanism highlights the tension between the need for secrecy in dangerous political climates and the requirement for transparency in the Church's governance. The existence of secret cardinals adds a layer of mystery to the College, reminding the faithful that the Church's leadership is not always fully visible, and that the pope may hold the power to elevate individuals to the highest ranks of the Church without public announcement.
The Ring And The Privilege
The personal life of a cardinal is marked by specific symbols and privileges that distinguish them from other clergy, most notably the gold ring given by the pope, which is traditionally kissed by Catholics as a sign of respect. This ring, which once featured a gemstone such as a sapphire with the pope's stemma engraved on the inside, now bears a modern depiction of the crucifixion of Jesus, with Mary and John to each side, and includes the pope's coat of arms on the inside. Cardinals also enjoy the privilege of forum, an exemption from being judged by ecclesiastical tribunals of ordinary rank, meaning that only the pope is competent to judge them in matters subject to ecclesiastical jurisdiction. This privilege ensures that cardinals are accountable only to the highest authority in the Church, reinforcing their status as the pope's closest advisors. Additionally, cardinals have the faculty to hear confessions validly and licitly everywhere, a power that is shared with bishops but can be restricted in particular areas by the local bishop. These privileges and symbols serve to reinforce the unique position of the cardinal within the Church, creating a sense of identity and responsibility that is both spiritual and administrative.
