Christianity in the 5th centuryIn the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God.
HeresyHeresy 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 Christianity, Judaism, and Islam has at times been met with censure ranging from excommunication to the death penalty. Heresy is distinct from apostasy, which is the explicit renunciation of one's religion, principles or cause; and from blasphemy, which is an impious utterance or action concerning God or sacred things.
EbionitesEbionites (Ebiōnaîoi, derived from Hebrew אֶבְיוֹנִים (or אֶבְיוֹנִם), ʾEḇyōnīm, meaning 'the poor' or 'poor ones') as a term refers to a Jewish Christian sect, which viewed poverty as a blessing, that existed during the early centuries of the Common Era. The Ebionites embraced an adoptionist Christology, thus understanding Jesus of Nazareth as a mere man who, by virtue of his righteousness in following the Law of Moses, was chosen by God to be the messianic "prophet like Moses".
MarcionismMarcionism was an early Christian dualistic belief system that originated with the teachings of Marcion of Sinope in Rome around the year 144. Marcion was an early Christian theologian, evangelist, and an important figure in early Christianity. He was the son of a bishop of Sinope in Pontus. About the middle of the 2nd century (140–155) he traveled to Rome, where he joined the Syrian Gnostic Cerdo.
Early ChristianityEarly Christianity, or Paleochristianity, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians. Early Christianity contains the Apostolic age and is followed by, and substantially overlaps with, the Patristic era.
Epistle of BarnabasThe Epistle of Barnabas (Βαρνάβα Ἐπιστολή) is a Greek epistle written between AD 70 and 132. The complete text is preserved in the 4th-century Codex Sinaiticus, where it appears immediately after the New Testament and before the Shepherd of Hermas. For several centuries it was one of the "antilegomena" ("disputed") writings that some Christians looked on as sacred scripture, while others excluded them. Eusebius of Caesarea classified it as such.
Christ myth theoryThe Christ myth theory, also known as the Jesus myth theory, Jesus mythicism, or the Jesus ahistoricity theory, is the view that the story of Jesus is a work of mythology with no historical substantiality. Alternatively, in terms given by Bart Ehrman paraphrasing Earl Doherty, "the historical Jesus did not exist. Or if he did, he had virtually nothing to do with the founding of Christianity." In contrast, the mainstream scholarly consensus holds that there was a historical Jesus who lived in 1st-century-CE Roman Judea, and that he was probably both baptized and crucified.
Chalcedonian ChristianityChalcedonian Christianity is a term referring to the branches of Christianity that accept and uphold theological resolutions of the Council of Chalcedon, the fourth ecumenical council, held in 451. Chalcedonian Christianity accepts the Christological Definition of Chalcedon, a Christian doctrine concerning the union of two natures (divine and human) in one hypostasis of Jesus Christ, who is thus acknowledged as a single person (prosopon).
Marcion of SinopeMarcion of Sinope (ˈmɑrkiən,_-siən; Μαρκίων Σινώπης; 85-160) was an early Christian theologian in early Christianity. Marcion preached that God had sent Jesus Christ, who was an entirely new, alien god, distinct from the "vengeful" God (Demiurge) who had created the world. He considered himself a follower of Paul the Apostle, whom he believed to have been the only true apostle of Jesus Christ; his doctrine is called Marcionism. Marcion published the earliest record of a canon of New Testament books.
Historical JesusThe term "historical Jesus" refers to the life and teachings of Jesus as interpreted through critical historical methods, in contrast to what are traditionally religious interpretations. It also considers the historical and cultural contexts in which Jesus lived. Virtually all scholars of antiquity accept that Jesus was a historical figure, and attempts to deny his historicity have been consistently rejected by the scholarly consensus as a fringe theory.
