The branch of theology concerned with the final things — the return of Christ, the resurrection of the dead, the last judgment, and the consummation of all things. Scripture frames eschatology not as speculation but as certain hope: history is moving toward a definitive end ordained by God, when all things will be summed up in Christ (Eph. 1:10). It encompasses both personal eschatology (death, individual judgment, heaven/hell) and cosmic eschatology (Christ's return, new creation). The Christian lives in the "already but not yet" — the Kingdom has broken in, but its fullness awaits.
Not yet coined in Webster's 1828 edition. The systematic study of last things emerged as a distinct theological discipline in the 19th century, though biblical reflection on the end times pervades both Testaments — from Daniel's visions to the Olivet Discourse to the Revelation of John.
Modern culture replaces divine eschatology with secular utopias — the progressive belief that history climaxes in human achievement rather than divine judgment. "Eschatology" is also trivially weaponized by sensationalists who turn the study of last things into date-setting spectacle, missing its pastoral purpose: that certainty of the end produces holiness, urgency in mission, and comfort in suffering.

"A robust eschatology does not produce passivity but urgency — knowing the King is returning, we labor all the more."
"The church's hope is eschatological: not the improvement of the present age but its transformation at Christ's coming."
"Eschatology shapes ethics: how we treat the poor, the stranger, and the unborn matters because each will stand before the Judge."
