TransubstantiationTransubstantiation (Latin: transubstantiatio; Greek: μετουσίωσις metousiosis) is, according to the teaching of the Catholic Church, "the change of the whole substance of bread into the substance of the Body of Christ and of the whole substance of wine into the substance of the Blood of Christ". This change is brought about in the eucharistic prayer through the efficacy of the word of Christ and by the action of the Holy Spirit. However, "the outward characteristics of bread and wine, that is the 'eucharistic species', remain unaltered".
Avignon PapacyThe Avignon Papacy (French: Papauté d'Avignon) was the period from 1309 to 1376 during which seven successive popes resided in Avignon (at the time within the Kingdom of Arles, part of the Holy Roman Empire; now part of France) rather than in Rome. The situation arose from the conflict between the papacy and the French crown, culminating in the death of Pope Boniface VIII after his arrest and maltreatment by Philip IV of France. Following the subsequent death of Pope Benedict XI, Philip forced a deadlocked conclave to elect the French Clement V as pope in 1305.
HussitesThe Hussites (Husité or Kališníci; "Chalice People") were a Czech proto-Protestant Christian movement that followed the teachings of reformer Jan Hus, who became the best known representative of the Bohemian Reformation. The Hussite movement began in the Kingdom of Bohemia and quickly spread throughout the remaining Lands of the Bohemian Crown, including Moravia and Silesia. It also made inroads into the northern parts of the Kingdom of Hungary (now Slovakia), but was rejected and gained infamy for the plundering behaviour of the Hussite soldiers.
WaldensiansThe Waldensians, also known as Waldenses (wɔːlˈdɛnsiːz,_wɒl-), Vallenses, Valdesi, or Vaudois, are adherents of a church tradition that began as an ascetic movement within Western Christianity before the Reformation. Originally known as the "Poor Men of Lyon" in the late twelfth century, the movement spread to the Cottian Alps in what are today France and Italy. The founding of the Waldensians is attributed to Peter Waldo, a wealthy merchant who gave away his property around 1173, preaching apostolic poverty as the way to perfection.
AntichristIn Christian eschatology, the Antichrist refers to people prophesied by the Bible to oppose Jesus Christ and substitute themselves in Christ's place before the Second Coming. The term Antichrist (including one plural form) is found four times in the New Testament, solely in the First and Second Epistle of John. The Antichrist is announced as the one "who denies the Father and the Son." The similar term pseudokhristos or "false Christ" is also found in the Gospels.
William of OckhamWilliam of Ockham, OFM (ˈɒkəm; also Occam, from Gulielmus Occamus; 1287 – 10 April 1347) was an English Franciscan friar, scholastic philosopher, apologist, and Catholic theologian, who is believed to have been born in Ockham, a small village in Surrey. He is considered to be one of the major figures of medieval thought and was at the centre of the major intellectual and political controversies of the 14th century. He is commonly known for Occam's razor, the methodological principle that bears his name, and also produced significant works on logic, physics and theology.
VernacularA vernacular or vernacular language is in contrast with a "standard language". It refers to the language or dialect that is spoken by people who are inhabiting a particular country or region. The vernacular is typically the native language, normally spoken informally rather than written, and seen as of lower status than more codified forms. It may vary from more prestigious speech varieties in different ways, in that the vernacular can be a distinct stylistic register, a regional dialect, a sociolect, or an independent language.
Sola fideJustificatio sola fide (or simply sola fide), meaning justification by faith alone, is a soteriological doctrine in Christian theology commonly held to distinguish the Lutheran and Reformed traditions of Protestantism, among others, from the Catholic, Eastern Orthodox, Oriental Orthodox and Assyrian churches. The doctrine asserts that it is on the basis of faith that believers are made right of their transgressions of divine law rather than on the basis of what Paul the Apostle calls "works of the law", sometimes called good works.
Council of ConstanceThe Council of Constance (Concilium Constantiense; Konzil von Konstanz) was an ecumenical council of the Catholic Church that was held from 1414 to 1418 in the Bishopric of Constance (Konstanz) in present-day Germany. The council ended the Western Schism by deposing or accepting the resignation of the remaining papal claimants and by electing Pope Martin V. It was the last papal election to take place outside of Italy.
Protestant ReformersProtestant Reformers were theologians whose careers, works and actions brought about the Protestant Reformation of the 16th century. In the context of the Reformation, Martin Luther was the first reformer, sharing his views publicly in 1517, followed by Andreas Karlstadt and Philip Melanchthon at Wittenberg, who promptly joined the new movement. In 1519, Huldrych Zwingli became the first reformer to express a form of the Reformed tradition. Listed are the most influential reformers only.
