Eschatology

Eschatology /ˌɛskəˈtɒlədʒi/ is a part of theology concerned with the final events of history, or the ultimate destiny of humanity. This concept is commonly referred to as the "end of the world" or "end time".

The word arises from the Greek ἔσχατος eschatos meaning "last" and -logy meaning "the study of", first used in English around 1550. The Oxford English Dictionary defines eschatology as "The department of theological science concerned with ‘the four last things: death, judgment, heaven and hell’."
