Heresy in ChristianityHeresy in Christianity denotes the formal denial or doubt of a core doctrine of the Christian faith as defined by one or more of the Christian churches. The study of heresy requires an understanding of the development of orthodoxy and the role of creeds in the definition of orthodox beliefs, since heresy is always defined in relation to orthodoxy. Orthodoxy has been in the process of self-definition for centuries, defining itself in terms of its faith by clarifying beliefs in opposition to people or doctrines that are perceived as incorrect.

History of Christian theologyThe doctrine of the Trinity, considered the core of Christian theology by Trinitarians, is the result of continuous exploration by the church of the biblical data, thrashed out in debate and treatises, eventually formulated at the First Council of Nicaea in AD 325 in a way they believe is consistent with the biblical witness, and further refined in later councils and writings. The most widely recognized Biblical foundations for the doctrine's formulation are in the Gospel of John, which possess ideas that originate in Platonism and Greek philosophy.
History of the Eastern Orthodox ChurchThe History of the Eastern Orthodox Church is the formation, events, and transformation of the Eastern Orthodox Church through time. According to the Eastern Orthodox tradition the history of the Eastern Orthodox Church is traced back to Jesus Christ and the Apostles. The Apostles appointed successors, known as bishops, and they in turn appointed other bishops in a process known as Apostolic succession. Over time, five Patriarchates were established to organize the Christian world, and four of these ancient Patriarchates remain Orthodox today.
Légat apostoliqueLe légat apostolique (du latin legatus, « envoyé »), ou plus communément légat du pape, ou légat pontifical, est un représentant extraordinaire du pape chargé d'une mission spécifique, généralement diplomatique. Il se distingue en cela du nonce apostolique qui est un ambassadeur permanent du Saint-Siège auprès des gouvernements étrangers. La pratique des légats n'est pas attestée avant le concile d'Arles, en 314, dont les souscriptions mentionnent quatre (missi) par l'évêque de Rome, Sylvestre.
