   19 April 2005–
   *In March 752 an elderly presbyter, Stephen, was elected pope, but died before he was ordained bishop. His successor, confusingly, was also called Stephen. Under modem canon law, however, a man is pope from the moment of election. Some modern Roman Catholic lists therefore count the first of these two Stephens as Pope Stephen II, with a consequent disturbance of the numbering of all subsequent Stephens. He is omitted from our list, but the variant numberings are noted.
   *Because John XII was deposed by the Emperor Otto I, the validity of Leo VIII’s election has been contested, and he is included as an antipope in many lists. The Roman Catholic Church’s official list of popes, as printed in the Annuario Pontificio, recognises him as a true pope.
   *Because of a mistake in the medieval numbering, no pope has ever borne the title John XX
   APPENDIX B
   GLOSSARY
   AD LIMINA: Latin for ‘to the threshold’, meaning a visit to the house of the Apostle Peter, i.e. Rome or St Peter’s Basilica. The phrase applied originally to all pilgrimage to the shrine of the Apostle. In modern usage it applies especially to the five-yearly visits bishops are required to make to Rome to give an account of their dioceses to the Pope. Currently seen as an expression of the COLLEGIAL responsibility of the bishops with the Pope, historically it has been a way of enforcing and underlining papal authority.
   ANTIPOPE: rival claimant to the papacy, elected or appointed in opposition to the incumbent subsequently recognised officially as the ‘true’ Pope. A complete list will be found in Appendix A.
   APOCRISIARY: papal ambassador to the Byzantine Emperor.
   ARCHBISHOP: the senior bishop of a region. Since the early Middle Ages the authority of the Archbishop over the subordinate or ‘suffragan’ bishops has been symbolised by the gift of the PALLIUM from the Pope.
   ARIANISM: Christian heresy preached originally by the Alexandrian presbyter Arius (died 336), denying the full divinity of Jesus Christ, and teaching that as ‘Son of God’ Christ was subordinate to God the Father, by whom he had been created before the beginning of the world. The teaching seems to have sprung from a concern to protect the sovereignty and unchanging nature of God from the limitations implied in the doctrine of the INCARNATION.
   BEATIFICATION: the solemn papal authorisation of religious cult in honour of a dead Christian; a step on the way to full CANONISATION or declaration that the canonised person is a saint.
   BISHOP: from Greek episcopos (‘overseer’); the senior pastor (‘shepherd’) and focus of unity within a Christian church: probably originally indistinguishable from the ‘elders’ (Greek ‘presbyter’, from which the word ‘priest’ is derived). Within the first hundred years of Christianity the bishops emerged as the chief ministers, to whom the government of the churches, and the right to ordain other ministers, was confined. The territory over which bishops rule is called a DIOCESE, though early bishops probably presided over the church in a single town. The Pope is Bishop of Rome.
   BRIEF: an official papal letter, less solemn than a papal bull.
   BULL: solemn papal document or mandate announcing a binding decision, and carrying a formal seal.
   BYZANTIUM, BYZANTINE: Byzantium was the Greek town on the Bosphorous where Constantine established the new capital of the Roman empire in 330, when it became Constantinople. It gave its name to the empire as a whole, to the state Church and to the distinctive liturgy of the Church. In contrast to the Latin Church, where the Pope’s authority came to be seen as supreme, the Byzantine Church paid special reverence to the Christian authority of the Emperor. After the Turkish conquest of 1453 Byzantium was renamed Istanbul.
   CANON: CANON LAW: (i) Formal item of Church law. (ii) A decree of a council or synod.
   CANONISATION: solemn declaration that a deceased Christian is a saint, to whom prayers and other religious honours may be paid. Originally canonisation was a matter for the local church, and was usually signalled and formalised by the ‘translation’ (transfer) by the bishop of the relics of the saint to a visible shrine, and the insertion of their feast day into the calendar of the local church. The first known papal canonisation was of Ulrich of Augsburg in 993; since the late twelfth century the power of canonisation has been reserved to the Pope alone.
   CARDINAL: from the Latin word cardo, a hinge. At first, any priest attached to a major church, later restricted to the parish clergy of Rome, the bishops of the SUBARBICARIAN DIOCESES, and the district DEACONS of Rome. The special advisers and helpers of the Pope and, since 1179, the exclusive electors of a new pope. Since 1970 they have been excluded from voting in a CONCLAVE after the age of eighty. Since the pontificate of Paul VI all cardinals have had to be ordained bishop, but historically they needed only to be in ‘minor orders’, and many of the most famous cardinals of history were never priests.
   COLLEGIALITY: the co-responsibility of all bishops, in communion with the Pope and with each other, for the whole Church. Emphasised in the teaching of early theologians like Cyprian of Carthage, it was obscured by the growth of the papal monarchy, but re-emphasised at the Second Vatican Council.
>
   CONCILIARISM, CONCILIAR THEORY: the doctrine that supreme authority in the Church lies with a GENERAL COUNCIL, rather than with the Pope: Conciliar theory had widespread support during the period of the Great Schism, and was only finally rejected by the definition of papal INFALLIBILITY in 1870.
   CONCLAVE: from the Latin con clave, ‘with a key’. Since 1271, the closed place into which the assembly of cardinals is locked to elect a new pope and, by extension, the assembly of cardinals themselves. Regulations until recently emphasised the need to make conditions in the Conclave as uncomfortable as possible, to speed the process of election.
   CONCORDAT: an agreement between the Church and a civil government to regulate religious affairs.
   CONSISTORY: the assembly of cardinals, convoked by the Pope and presided over by him, to advise the Pope or witness solemn papal acts.
   COUNCIL, ECUMENICAL COUNCIL, GENERAL COUNCIL: a solemn assembly of bishops to determine matters of doctrine or discipline for the Church. Councils called for the whole empire, the Oecumene, were called ‘ecumenical’ or general councils, and their solemn teaching was believed to be INFALLIBLE. The first of these general councils was Nicaea, called by the Emperor Constantine in 325 to settle the Arian controversy. In Catholic theology, no general council can meet without papal agreement.
