An antipope is a person who claims to be Bishop of Rome and leader of the Roman Catholic Church in opposition to the legitimately elected pope. Between the 3rd and mid-15th centuries, antipopes were supported by factions within the Church itself and secular rulers.
Robert Bellarmine was an Italian Jesuit and a cardinal of the Catholic Church. He was canonized a saint in 1930 and named Doctor of the Church, one of only 37. He was one of the most important figures in the Counter-Reformation.
The pope is the bishop of Rome and the visible head of the worldwide Catholic Church. He is also known as the supreme pontiff, Roman pontiff, or sovereign pontiff. From the eighth century until 1870, the pope was the sovereign or head of state of the Papal States, and since 1929 of the much smaller Vatican City state. From a Catholic viewpoint, the primacy of the bishop of Rome is largely derived from his role as the apostolic successor to Saint Peter, to whom primacy was conferred by Jesus, who gave Peter the Keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the Church would be built. The reigning pope is Francis, who was elected on 13 March 2013.
Pope Damasus I, also known as Damasus of Rome, was the bishop of Rome from October 366 to his death in 384. It is claimed that he presided over the Council of Rome of 382 that determined the canon or official list of sacred scripture.
Pope Honorius I was the bishop of Rome from 27 October 625 to his death. He was active in spreading Christianity among Anglo-Saxons and attempted to convince the Celts to calculate Easter in the Roman fashion. He is chiefly remembered for his correspondence with Patriarch Sergius I of Constantinople over the latter's monothelite teachings. Honorius was posthumously anathematized, initially for subscribing to monothelitism, and later only for failing to end it. The anathema against Honorius I became one of the central arguments against the doctrine of papal infallibility.
Pope Boniface I was the bishop of Rome from 28 December 418 to his death on 4 September 422. His election was disputed by the supporters of Eulalius until the dispute was settled by Emperor Honorius. Boniface was active in maintaining church discipline, and he restored certain privileges to the metropolitical sees of Narbonne and Vienne, exempting them from any subjection to the primacy of Arles. He was a contemporary of Augustine of Hippo, who dedicated to him some of his works.
Pope Boniface IV, OSB was the bishop of Rome from 608 to his death. Boniface had served as a deacon under Pope Gregory I, and like his mentor, he ran the Lateran Palace as a monastery. As pope, he encouraged monasticism. With imperial permission, he converted the Pantheon into a church. In 610, he conferred with Bishop Mellitus of London regarding the needs of the English Church. He is venerated as a saint in the Catholic Church with a universal feast day on 8 May.
Pope Urban II, otherwise known as Odo of Châtillon or Otho de Lagery, was the head of the Catholic Church and ruler of the Papal States from 12 March 1088 to his death. He is best known for convening the Council of Clermont which ignited the series of Christian military expeditions known as the Crusades.
Pope Victor III, was the head of the Catholic Church and ruler of the Papal States from 24 May 1086 to his death. He was the successor of Pope Gregory VII, yet his pontificate is far less notable than his time as Desiderius, the great abbot of Monte Cassino.
Pope Leo I, also known as Leo the Great, was Bishop of Rome from 29 September 440 until his death. He is the first of the three Popes listed in the Annuario Pontificio with the title "the Great", alongside Popes Gregory I and Nicholas I.
Pope Paschal II, born Ranierius, was head of the Catholic Church and ruler of the Papal States from 13 August 1099 to his death in 1118. A monk of the Abbey of Cluny, he was created the cardinal-priest of San Clemente by Pope Gregory VII (1073–85) in 1073. He was consecrated as pope in succession to Pope Urban II (1088–99) on 19 August 1099. His reign of almost twenty years was exceptionally long for a medieval pope.
Pope Leo IX, born Bruno von Egisheim-Dagsburg, was the head of the Catholic Church and ruler of the Papal States from 12 February 1049 to his death in 1054. Leo IX is considered to be one of the most historically significant popes of the Middle Ages; he was instrumental in the precipitation of the Great Schism of 1054, considered the turning point in which the Catholic and Eastern Orthodox Churches formally separated.
The College of Cardinals, more formally called the Sacred College of Cardinals, is the body of all cardinals of the Catholic Church. As of 31 December 2024, there are 252 cardinals, of whom 139 are eligible to vote in a conclave to elect a new pope. Cardinals are appointed by the pope for life but eligibility to vote ceases at the age of 80.
The Western Schism, also known as the Papal Schism, the Great Occidental Schism, the Schism of 1378, or the Great Schism, was a split within the Catholic Church lasting from 20 September 1378 to 11 November 1417, in which bishops residing in Rome and Avignon simultaneously claimed to be the true pope, and were eventually joined by a third line of Pisan claimants in 1409. The event was driven by international rivalries, personalities and political allegiances, with the Avignon Papacy in particular being closely tied to the French monarchy.
Quartodecimanism is the name given to the practice of celebrating the death of Christ on the day of Passover, the 14th of Nisan according to biblical dating, on whatever day of the week it occurs. The Quartodeciman controversy in the Church was the question of whether to celebrate Easter on Sunday, or Passover.
The purpose of this timeline is to give a detailed account of Christianity from the beginning of the current era (AD) to the present. Question marks ('?') on dates indicate approximate dates.
Papal supremacy is the doctrine of the Catholic Church that the Pope, by reason of his office as Vicar of Christ, the visible source and foundation of the unity both of the bishops and of the whole company of the faithful, and as pastor of the entire Catholic Church, has full, supreme, and universal power over the whole church, a power which he can always exercise unhindered: that, in brief, "the Pope enjoys, by divine institution, supreme, full, immediate, and universal power in the care of souls."
Christianity in late antiquity traces Christianity during the Christian Roman Empire — the period from the rise of Christianity under Emperor Constantine, until the fall of the Western Roman Empire. The end-date of this period varies because the transition to the sub-Roman period occurred gradually and at different times in different areas. One may generally date late ancient Christianity as lasting to the late 6th century and the re-conquests under Justinian of the Byzantine Empire, though a more traditional end-date is 476, the year in which Odoacer deposed Romulus Augustus, traditionally considered the last western emperor.
In the Catholic Church, the Synod of Bishops, considered as an advisory body for the pope, is one of the ways in which the bishops render cooperative assistance to him in exercising his office. It is described in the 1983 Code of Canon Law as "a group of bishops who have been chosen from different regions of the world and meet at fixed times to foster closer unity between the Roman Pontiff and bishops, to assist the Roman Pontiff with their counsel in the preservation and growth of faith and morals and in the observance and strengthening of ecclesiastical discipline, and to consider questions pertaining to the activity of the Church in the world."
The COVID-19 pandemic that started in 2020 has significantly impacted liturgical celebrations of the Catholic Church worldwide. The Pontifical Foundation Aid to the Church in Need (ACN) stated that the pandemic has become not "just a medical, social and economic problem, but also a pastoral problem", which led ACN to start encouraging a special program for the actions of priests and religious against the virus spread.
