Definition

Eschatology (from Greek eschatos, “last”) is the doctrine of the last things — the consummation of God’s redemptive purpose in death, the intermediate state, the second coming of Christ, the resurrection of the dead, the final judgment, and the eternal state of the new heavens and new earth. It treats both individual eschatology (what becomes of each person at death) and cosmic eschatology (the renewal of all creation at Christ’s return). Reformed eschatology is covenantal and Christ-centered: it confesses that the last days were inaugurated in Christ’s first coming and will be consummated at his second, holding the tension of the kingdom “already” present and “not yet” perfected. On the millennium, the Reformed tradition has chiefly embraced amillennialism, while including respected postmillennial and historic premillennial voices.

Why It Matters

Eschatology is no idle speculation about charts and timelines; it is the doctrine of Christian hope. It answers the deepest questions of the soul: What happens when I die? Will death be undone? Will Christ return? Will justice be done and the world made right? Without a sure eschatology, the believer is left to fear death and to despair of the world’s evil. With it, the believer faces death “in full assurance” (WCF 32), longs for the appearing of his Lord, and labors in the present age knowing his labor is not in vain (1 Cor. 15:58). Eschatology also disciplines the church against both the escapism that neglects this world and the utopianism that expects heaven by human effort.

Map of the Locus

This locus unfolds in three principal studies, surveyed here.

Death and the Intermediate State

At death the body returns to dust and the soul, being immortal, returns to God who gave it. The souls of the righteous, made perfect in holiness, are received into the presence of Christ in glory; the souls of the wicked are cast into torment, both awaiting the resurrection. The Reformed deny “soul sleep” and any purgatory, confessing that the believer departs to be “with Christ” (Phil. 1:23), conscious and blessed, in the intermediate state between death and resurrection.

The Second Coming and the Millennium

Christ will return personally, visibly, bodily, and gloriously to judge the living and the dead and to consummate his kingdom. His coming is single and climactic, not divided into secret and public phases. The “thousand years” of Revelation 20 is interpreted by amillennialism as the present reign of Christ and the souls of the departed saints during the whole gospel age, to be followed by his return, the general resurrection, and the final judgment — over against premillennial, postmillennial, and dispensational schemes.

Resurrection, Judgment, and the Eternal State

At Christ’s return the dead will be raised bodily — the just to life, the unjust to condemnation — and the living transformed. All will stand before the judgment seat of Christ, who will render to each according to his works as the evidence of his state. The wicked will go into everlasting punishment, the righteous into everlasting life. The final state is not a disembodied heaven but the new heavens and new earth, wherein the redeemed, raised and glorified, dwell forever with God and the Lamb.

Historical Development

The early church confessed in the creeds “the resurrection of the body and the life everlasting” and the return of Christ “to judge the living and the dead.” Augustine, in The City of God, set the dominant amillennial interpretation of Revelation 20 that prevailed through the medieval and Reformation church, identifying the millennium with the present church age. The medieval church added the errors of purgatory and a treasury of merit. The Reformers purged these, recovering the believer’s immediate entrance into glory at death and the centrality of the resurrection hope. Postmillennialism flourished among the Puritans and in later evangelicalism; historic premillennialism has had Reformed adherents; dispensational premillennialism arose in the nineteenth century outside the Reformed tradition. The Westminster Standards (WCF 32–33) gave classic confessional shape to the doctrine of the last things.

The Reformed & Confessional Position

The Confession addresses the state of men after death and the resurrection, and the last judgment.

The bodies of men, after death, return to dust, and see corruption: but their souls, which neither die nor sleep, having an immortal subsistence, immediately return to God who gave them. The souls of the righteous, being then made perfect in holiness, are received into the highest heavens… and the souls of the wicked are cast into hell. Besides these two places, for souls separated from their bodies, the Scripture acknowledgeth none. (WCF 32.1)

God hath appointed a day, wherein he will judge the world, in righteousness, by Jesus Christ… The end of God’s appointing this day is for the manifestation of the glory of his mercy, in the eternal salvation of the elect; and of his justice, in the damnation of the reprobate. (WCF 33.1–2)

The Shorter Catechism teaches that believers at death are made perfect in holiness and pass immediately into glory, their bodies resting in their graves till the resurrection (WSC Q. 37), and that at the resurrection believers, raised up in glory, shall be openly acknowledged and acquitted in the day of judgment and made perfectly blessed in the full enjoying of God forever (WSC Q. 38).

Contrasting Views

The chief intramural debate among Christians concerns the millennium. Amillennialism (the majority Reformed view) holds that the millennium is the present gospel age, with Christ reigning and the departed saints living with him, ended by his single return. Postmillennialism expects the gospel to triumph and Christianize the nations before Christ returns. Historic premillennialism holds that Christ returns before a literal earthly millennium. Dispensational premillennialism adds a pretribulational rapture, a sharp Israel/church distinction, and a future earthly Jewish kingdom. On the eternal state, annihilationism (or conditional immortality) denies the conscious, eternal punishment of the wicked, holding that they are finally destroyed; universalism holds that all are at last saved. The Reformed, from Scripture, affirm everlasting conscious punishment and everlasting life. These positions are weighed in the studies that follow.

Connections to Other Loci

Eschatology gathers up the whole of theology. It consummates soteriology, for glorification is the last link in the golden chain (Rom. 8:30). It rests on Christology, for the risen Christ is the firstfruits and the returning Judge. It fulfills covenant theology, bringing the covenant of grace to its goal in the new creation. It vindicates the justice and mercy of God in the final judgment, and it completes ecclesiology, perfecting the church militant as the church triumphant.

Christ & the Gospel at the Center

The last things are Christ’s things. He is the resurrection and the life (John 11:25); his rising is the firstfruits guaranteeing ours (1 Cor. 15:20–23); his return is the church’s blessed hope (Titus 2:13); he is the Judge before whose throne all will stand; and he is the light of the new Jerusalem, where his servants will see his face (Rev. 22:4). The believer’s eschatological hope is therefore not an abstraction but a person: to be with Christ, to be like Christ, and to behold Christ forever. The gospel that justifies the sinner now will glorify him then; the same grace that saved will be crowned in glory.

Pastoral & Practical Significance

Eschatology arms the believer to face death without terror, knowing he departs to be with Christ. It comforts the bereaved, for the dead in Christ are not lost but glorified and will be raised. It sustains the persecuted and suffering, who look for the day when Christ will set all things right. It motivates holiness, for “everyone who thus hopes in him purifies himself” (1 John 3:3). And it fuels mission and perseverance, for the King is coming and his kingdom cannot fail. The church lives between the times, watching, working, and waiting for the appearing of her Lord.
