New CovenantThe New Covenant (Hebrew beˈʁit χaˈdaʃah; Koine Greek διαθήκη καινή diathḗkē kainḗ ðiaˈθici ceˈni) is a biblical interpretation which was originally derived from a phrase which is contained in the Book of Jeremiah (Jeremiah 31:31–34), in the Hebrew Bible (or the Old Testament of the Christian Bible). Generally, Christians believe that the promised New Covenant was instituted at the Last Supper as part of the Eucharist, which, in the Gospel of John, includes the New Commandment.
Third TempleThe "Third Temple" (, Bēṯ hamMīqdāš hašŠlīšī, ) refers to a hypothetical rebuilt Temple in Jerusalem. It would succeed Solomon's Temple and the Second Temple, the former having been destroyed during the Babylonian siege of Jerusalem in 587 BCE and the latter having been destroyed during the Roman siege of Jerusalem in 70 CE. Although it remains unbuilt, the notion of and desire for the Third Temple is sacred in Judaism, and particularly in Orthodox Judaism; it is anticipated as the most sacred place of worship for Jews.
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.
SupersessionismSupersessionism, also called replacement theology or fulfillment theology, is a Christian theology which describes the theological conviction that the Christian Church has superseded the nation of Israel assuming their role as God's covenanted people, thus asserting that the New Covenant through Jesus Christ has superseded or replaced the Mosaic covenant exclusive to Jews. Supersessionist theology also holds that the universal Christian Church has succeeded ancient Israel as God's true Israel and that Christians have succeeded the ancient Israelites as the people of God.
PostmillennialismIn Christian eschatology (end-times theology), postmillennialism, or postmillenarianism, is an interpretation of chapter 20 of the Book of Revelation which sees Christ's second coming as occurring after (Latin post-) the "Millennium", a Golden Age in which Christian ethics prosper. The term subsumes several similar views of the end times, and it stands in contrast to premillennialism and, to a lesser extent, amillennialism (see Summary of Christian eschatological differences).
Abrahamic religionsThe Abrahamic religions are a group of religions centered around the worship of the God of Abraham. Abraham, a Hebrew patriarch, is extensively mentioned throughout the Abrahamic religious scriptures of the Quran, and the Hebrew and Christian Bibles. Jewish tradition claims that the Twelve Tribes of Israel are descended from Abraham through his son Isaac and grandson Jacob, whose sons formed the nation of the Israelites in Canaan (or the Land of Israel); Islamic tradition claims that twelve Arab tribes known as the Ishmaelites are descended from Abraham through his son Ishmael in the Arabian Peninsula.
PremillennialismPremillennialism, in Christian eschatology, is the belief that Jesus will physically return to the Earth (the Second Coming) before the Millennium, heralding a literal thousand-year golden age of peace. Premillennialism is based upon a literal interpretation of in the New Testament, which describes Jesus's reign in a period of a thousand years.
Great ApostasyThe Great Apostasy is a concept within Christianity to describe a perception that mainstream Christian Churches have fallen away from the original faith founded by Jesus and promulgated through his twelve Apostles. A belief in a Great Apostasy has been characteristic of the Restorationist tradition of Christianity, which includes unrelated Restorationist groups emerging after the Second Great Awakening, such as the Christadelphians, Latter Day Saints, Jehovah's Witnesses, and Iglesia ni Cristo.
