Christian eschatologyChristian eschatology, a major branch of study within Christian theology, deals with the doctrine of the "last things", especially the Second Coming of Christ, or Parousia. Eschatology – the word derives from two Greek roots meaning "last" (ἔσχατος) and "study" (-λογία) – involves the study of "end things", whether of the end of an individual life, of the end of the age, of the end of the world, or of the nature of the Kingdom of God.
EschatologyEschatology (ˌɛskəˈtɒlədʒi; ) concerns expectations of the end of the present age, human history, or the world itself. The end of the world or end times is predicted by several world religions (both Abrahamic and non-Abrahamic), which teach that negative world events will reach a climax. Belief that the end of the world is imminent is known as apocalypticism, and over time has been held both by members of mainstream religions and by doomsday cults.
Saint PeterSaint Peter (died between AD 64 and 68), also known as Peter the Apostle, Simon Peter, Simeon, Simon, or Cephas ( () 'rock'), was one of the Twelve Apostles of Jesus Christ and one of the first leaders of the early Christian Church. He appears repeatedly and prominently in all four New Testament gospels as well as the Acts of the Apostles. According to Christian tradition, Peter was crucified in Rome under Emperor Nero.
ApocalypticismApocalypticism is the religious belief that the end of the world is imminent, even within one's own lifetime. This belief is usually accompanied by the idea that civilization will soon come to a tumultuous end due to some sort of catastrophic global event. Apocalypticism is one aspect of eschatology in certain religions—the part of theology concerned with the final events of world history, or the ultimate destiny of humanity (societal collapse, human extinction, etc.).
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.
Restoration MovementThe Restoration Movement (also known as the American Restoration Movement or the Stone–Campbell Movement, and pejoratively as Campbellism) is a Christian movement that began on the United States frontier during the Second Great Awakening (1790–1840) of the early 19th century. The pioneers of this movement were seeking to reform the church from within and sought "the unification of all Christians in a single body patterned after the church of the New Testament.
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.
