NUMBER OF CARDINALS
183 (from 66 countries)

NUMBER OF CARDINAL ELECTORS
117 (from 52 countries)
(as of 2005.03.21)

According to the apostolic letter Ingravescentem Aetetem effective 1971.01.01, Cardinals who have completed their 80th year of age can no longer take part in a papal election. Pope John Paul II has used his authority to exceed the limit of 120. Cardinals are chosen by the pope to serve as his principal assistants and advisers in the central administration of church affairs. Collectively, they form the College of Cardinals or the Sacred College. Under the Code of Canon Law, Cardinals serve to govern the Church and elect the pope in a conclave during the Sede Vacante (when the Holy See becomes vacant). Cardinals are also the major administrators of church affairs, serving in one or more departments of the Roman Curia.

Their title, while symbolic of high honour, does not signify any extension of the powers of the holy orders. By the 1815 Congress of Vienna, all Cardinals have the rank and privileges equal to princes of royal birth; hence they are also known as the princes of the Church. Cardinals in pectore are those who have been selected by the pope but whose name have not been disclosed usually because of political reasons. They have no title, rights or duties until such disclosure is made. Two Cardinals named in pectore by Pope John Paul II were revealed on 2001.01.28. One prelate was named in pectore on 2003.09.28, and his name has not been revealed.
