Christian eschatology

Christian eschatology is the theological study of the "last things," a term rooted in the Greek words for "last" and "study." It examines the end of an individual life, the close of an age, the conclusion of the world, and the nature of God's Kingdom, with a particular focus on the Second Coming of Christ, known as the Parousia. This field primarily concerns the ultimate fate of individual souls and the whole created order, drawing its core material from biblical texts in both the Old and New Testaments. Topics covered include death, the afterlife, Heaven, Hell, the resurrection of the dead, the rapture, the tribulation, millennialism, the Last Judgment, and the eventual New Heaven and New Earth. Eschatological passages appear throughout the Bible, and additional prophecies and ecclesiastical traditions exist outside of scripture.

The origins of Christian eschatology lie in the public ministry and teachings of Jesus. Passages such as Matthew 24:27, 24:37–39, 26:64, and Mark 14:62 are often interpreted as references to his Second Coming. This branch of theology is ancient, informed by the Olivet Discourse (found in Matthew 24–25, Mark 13, and Luke 21), the parable of the Sheep and the Goats, and other end-times teachings of Jesus. The apostle Paul discusses the Second Coming in his epistles, both those considered authentic and disputed. Further eschatological doctrines appear in the Epistle of James, First Peter, and First John. Some scholars point to Second Peter (3:3–9) as explaining God’s patience in delaying the Parousia to allow more people to repent and be saved, urging Christians to wait patiently and study scripture. Others argue that the New Testament epistles encourage early believers to expect Jesus’ imminent return, as he predicted in the gospels. Around 95 AD, Pope Clement I’s First Epistle criticized those whose faith wavered because the Second Coming had not yet occurred.

Ignatius of Antioch (c. 35–107 AD) also addressed eschatology in his letters, and the topic was further developed by Justin Martyr (c. 100–165). In the West, Tertullian (c. 160–225) continued this work, with Origen (c. 185–254) providing deeper reflection. The term "eschatology" itself was first used by Lutheran theologian Abraham Calovius (1612–1686) but only became common in the 19th century. Modern interest in the subject grew within Anglophone Christianity. Eighteenth- and nineteenth-century Puritans focused on a postmillennial hope tied to Christian conversion, contrasting with the premillennialism promoted by dispensationalists like J. N. Darby. Both strands influenced Christian missions and the development of eschatology in West Africa and Asia. In the 20th century, German scholars such as Jürgen Moltmann and Wolfhart Pannenberg also contributed to the field. During the 1800s, theologians including Ellen G. White, William Miller, and Joseph Bates studied eschatological themes in the Book of Daniel and Revelation, leading to the founding of the Seventh-day Adventist church.

Several approaches have emerged from studying the Book of Revelation, Christianity’s central eschatological text, though they can apply to all biblical prophecy. These methods are not mutually exclusive and are often combined. The Jesuit-originated methods of Futurism and Preterism were developed to counter the Historicist interpretation, which Reformers had used to identify the Papacy as the Antichrist.

Preterism interprets some (partial preterism) or all (full preterism) biblical prophecies as already fulfilled. It sees the Book of Daniel as referring to events from the 7th century BC to the 1st century AD, and Revelation as describing events of the 1st century AD. This view holds that Ancient Israel continued or was fulfilled in the Christian church at the destruction of Jerusalem in 70 AD. The first systematic preterist exposition is generally credited to Jesuit Luis de Alcasar (1554–1613), whose *Vestigatio arcani sensus in Apocalypsi* was published in 1614 during the Counter-Reformation.

Historicism is a method that associates biblical symbols with historical persons, nations, or events, leading to a view of progressive and continuous fulfillment of prophecy across the centuries.
