Second ComingThe Second Coming (sometimes called the Second Advent or the Parousia) is a Christian and Islamic belief that Jesus will return after his ascension to heaven (which occurred about two thousand years ago). The idea is based on messianic prophecies and is part of most Christian eschatologies. Other faiths have various interpretations of it. Theophany and Christophany Several different terms are used to refer to the Second Coming of Christ: In the New Testament, the Greek word ἐπιφάνεια (epiphaneia, appearing) is used five times to refer to the return of Christ.
Book of RevelationThe Book of Revelation, also erroneously called the Book of Revelations, is the final book of the New Testament (and therefore the final book of the Christian Bible). Written in Koine Greek, its title is derived from the first word of the text: apokalypsis, meaning 'unveiling' or 'revelation'. The Book of Revelation is the only apocalyptic book in the New Testament canon. It occupies a central place in Christian eschatology. The author names himself as simply "John" in the text, but his precise identity remains a point of academic debate.
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.
