Heresy is any belief or theory that is strongly at variance with established beliefs or customs, particularly the accepted beliefs or religious law of a religious organization. A heretic is a proponent of heresy.
Heresy in Judaism, Christianity, and Islam has at times been met with censure ranging from excommunication to the death penalty.
The expression "one true church" refers to an ecclesiological position asserting that Jesus gave his authority in the Great Commission solely to a particular visible Christian institutional church—what is commonly called a denomination. This view is maintained by the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox communion, the Assyrian Church of the East, the Ancient Church of the East, and the Lutheran churches, as well as certain Baptists. Each of them maintains that their own specific institutional church (denomination) exclusively represents the one and only original church. The claim to the title of the "one true church" relates to the first of the Four Marks of the Church mentioned in the Nicene Creed: "one, holy, catholic, and apostolic church". As such, it also relates to claims of both catholicity and apostolic succession: asserting inheritance of the spiritual, ecclesiastical and sacramental authority and responsibility that Jesus Christ gave to the apostles.
The concept of schism somewhat moderates the competing claims between some churches—one can potentially repair schism, since they are striving for the same goal. For example, the Catholic and Eastern Orthodox churches each regard the other as schismatic and at very least heterodox, if not heretical, yet both have held dialogues and even partaken in Councils in attempts to resolve the division that exists between them.
The Banate of Bosnia (Serbo-Croatian: Banovina Bosna / Бановина Босна), or Bosnian Banate (Bosanska banovina / Босанска бановина), was a medieval state located in what is today Bosnia and Herzegovina. Although Hungarian kings viewed Bosnia as part of Hungarian Crown Lands, the Banate of Bosnia was a de facto independent state for most of its existence. It was founded in the mid-12th century and existed until 1377 with interruptions under the Šubić family between 1299 and 1324. In 1377, it was elevated to a kingdom. The greater part of its history was marked by a religiopolitical controversy revolving around the native Christian Bosnian Church condemned as heretical by the dominant Chalcedonian Christian churches, namely the Catholic and Eastern Orthodox churches, with the Catholic Church being particularly antagonistic and persecuting its members through the Hungarians.
Etymologiae (Latin for 'Etymologies'), also known as the Origines ('Origins'), usually abbreviated Orig., is an etymological encyclopedia compiled by the influential Christian bishop Isidore of Seville (c. 560–636) towards the end of his life. Isidore was encouraged to write the book by his friend Braulio, Bishop of Saragossa. Etymologiae summarized and organized a wealth of knowledge from hundreds of classical sources; three of its books are derived largely from Pliny the Elder's Natural History. Isidore acknowledges Pliny, but not his other principal sources, namely Cassiodorus, Servius, and Gaius Julius Solinus.
Etymologiae covers an encyclopedic range of topics. Etymology, the origins of words, is prominent, but the work also covers, among other things, grammar, rhetoric, mathematics, geometry, music, astronomy, medicine, law, the church and heretical sects, pagan philosophers, languages, cities, humans, animals, the physical world, geography, public buildings, roads, metals, rocks, agriculture, war, ships, clothes, food, and tools.
The Index Librorum Prohibitorum (English: Index of Forbidden Books) was a changing list of publications deemed heretical or contrary to morality by the Sacred Congregation of the Index (a former dicastery of the Roman Curia); Catholics were forbidden to print or read them, subject to the local bishop. Catholic states could enact laws to adapt or adopt the list and enforce it.
The Index was active from 1560 to 1966. It banned thousands of book titles and blacklisted publications, including the works of Europe's intellectual elites.
Heinrich Cornelius Agrippa von Nettesheim (/əˈɡrɪpə/; German: [aˈgʀɪpa]; 14 September 1486 – 18 February 1535) was a German Renaissance polymath, physician, legal scholar, soldier, knight, theologian, and occult writer.
Agrippa's Three Books of Occult Philosophy published in 1533 drew heavily upon Kabbalah, Hermeticism, and Neoplatonism. His book was widely influential among esotericists of the early modern period, and was condemned as heretical by the inquisitor of Cologne.
Emeric, also known as Henry or Imre (Hungarian: Imre, Croatian: Emerik, Slovak: Imrich; 1174 – 30 November 1204), was King of Hungary and Croatia between 1196 and 1204. In 1184, his father, Béla III of Hungary, ordered that he be crowned king, and appointed him as ruler of Croatia and Dalmatia around 1195. Emeric ascended the throne after the death of his father. During the first four years of his reign, he fought his rebellious brother, Andrew, who forced Emeric to make him ruler of Croatia and Dalmatia as appanage.
Emeric cooperated with the Holy See against the Bosnian Church, which the Catholic Church considered to be heretical. Taking advantage of a civil war, Emeric expanded his suzerainty over Serbia. He failed to prevent the Republic of Venice, which was assisted by crusaders of the Fourth Crusade, from seizing Zadar in 1202. He also could not impede the rise of Bulgaria along the southern frontiers of his kingdom. Emeric was the first Hungarian monarch to use the "Árpád stripes" as his personal coat of arms and to adopt the title of King of Serbia. Before his death, Emeric had his four-year-old son, Ladislaus III, crowned king.
