World religion in the context of "Ninian Smart"

Eschatology (/ˌɛskəˈtɒlədʒi/ ; from Ancient Greek ἔσχατος (éskhatos) 'last' and -logy) concerns expectations of the end of 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 Dharmic), 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. In the context of mysticism, the term refers metaphorically to the end of ordinary reality and to reunion with the divine. Many religions treat eschatology as a future event prophesied in sacred texts or in folklore, while other religions may have concepts of renewal or transformation after significant events.

The Abrahamic religions maintain a linear cosmology, with end-time scenarios containing themes of transformation and redemption. In Judaism, the term "end of days" makes reference to the Messianic Age and includes an in-gathering of the exiled Jewish diaspora, the coming of the Messiah, the resurrection of the righteous, and the world to come. Christianity depicts the end time as a period of tribulation that precedes the second coming of Christ, who will face the rise of the Antichrist along with his power structure and false prophets, and usher in the Kingdom of God. The explicit description of a new earth is primarily found in Christian teachings (this description can be found in Chapter 21 of the Book of Revelation). In later traditions of Islam, separate hadiths detail the Day of Judgment as preceded by the appearance of the Masīḥ ad-Dajjāl, and followed by the descending of ʿĪsā (Jesus), which shall triumph over the false Messiah or Antichrist; his defeat will lead to a sequence of events that will end with the sun rising from the west and the beginning of the Qiyāmah (Judgment Day).

World Christianity or global Christianity has been defined both as a term that attempts to convey the global nature of the Christian religion and an academic field of study that encompasses analysis of the histories, practices, and discourses of Christianity as a world religion and its various forms as they are found on the six continents. However, the term often focuses on "non-Western Christianity" which "comprises (usually the exotic) instances of Christian faith in 'the global South', in Asia, Africa, and Latin America." It also includes Indigenous or diasporic forms of Christianity in the Caribbean, South America, Western Europe, and North America.

Oomoto (大本, Ōmoto; lit. "Great Source" or "Great Origin"), also known as Oomoto-kyo (大本教, Ōmoto-kyō), is a religion founded in the 1890s by Deguchi Nao (1836–1918) and Deguchi Onisaburō (1871–1948). Oomoto is typically categorized as a Shinto-based Japanese new religion. The spiritual leaders of the movement have always been women within the Deguchi family, along with Onisaburō as its founding seishi (spiritual teacher). Since 2001, the movement has been guided by its fifth leader, Kurenai Deguchi.

Oomoto's administrative headquarters is in Kameoka, Kyoto (Onisaburo Deguchi's hometown), and its spiritual headquarters is in Ayabe, Kyoto (Nao Deguchi's hometown). Uniquely among Japanese religions, Oomoto makes extensive use of the constructed language Esperanto to promote itself as a world religion. Oomoto has historically engaged in extensive interfaith dialogue with religions such as the Baháʼí Faith, Christianity, and Islam, since a key tenet of Oomoto is that all religions come from the same source (in Japanese: bankyō dōkon (万教同根)).
