The eschaton is the final, climactic event toward which all of history moves β the return of Christ, the resurrection of the dead, the last judgment, the renewal of all things, and the consummation of the Kingdom of God. It is not an escape from history but the transformation and fulfillment of it. The Bible presents history as teleological β purposeful, linear, heading toward a God-ordained end. The eschaton is not mere termination but telos (goal). The NT teaches a "now and not yet" eschatology: the kingdom has already broken in through Christ's first coming (inaugurated eschatology), but the fullness awaits his return (consummated eschatology). Every Lord's Supper is an eschatological meal β "until he comes" (1 Cor 11:26).
Webster 1828 predates the technical theological use of "eschaton" as a standalone noun; the concept was treated under "last things" and "judgment."
LAST, a. [Sax. latst or laetst.] Coming after all others; final; hindmost in place; latest in time; beyond which there is no more.
END, n. The extreme point of a line, or of anything that has more length than breadth; the conclusion; termination; ultimate state; final purpose or design; the object aimed at.

β’ 1 Corinthians 15:24β28 β The eschatological sequence: Christ's return, defeat of death, handing the kingdom to the Father; "that God may be all in all."
β’ Acts 3:21 β "Heaven must receive [Christ] until the time for restoring all the things about which God spoke by the mouth of his holy prophets."
β’ 2 Peter 3:10β13 β The day of the Lord; the present order dissolved; "we are waiting for new heavens and a new earth in which righteousness dwells."
β’ John 5:28β29 β "An hour is coming when all who are in the tombs will hear his voice and come out."
Two modern distortions dominate. First, escapist eschatology β treating the Second Coming primarily as an evacuation plan (Left Behind theology), emptying Christians of earthly responsibility by suggesting the world will be destroyed rather than renewed. This produces passive disengagement from culture, creation care, and justice β none of which Scripture supports. Second, realized eschatology in liberal theology collapses the eschaton entirely into the present: the Kingdom is simply social progress, justice work, or human flourishing β with no future return of Christ, no resurrection, no judgment. Both errors are catastrophic. The biblical vision is a real, future, bodily return of Christ β not an escape from creation but the redemption of it. The eschaton is not Plan B; it is the goal God set before the foundation of the world.
