eschatological \es-kuh-tl-OJ-i-kuhl\, adjective:
1. Regarding last, or final, matters, often of a theological nature.
2. Regarding any system of doctrines concerning theological endings, such as death, the Judgment, the future state, etc.
Eschatological is built from the Greek roots eschatos, “last, furthest, remote,” and logia, “a speaking” (in a certain manner). In theology, the study of the four last things: death, judgment, heaven, hell.
Sometimes I wonder: if Fyodor Dostoevsky was to have an eschatological-themed party, who would he invite?
