In the Coptic Orthodox tradition, the Church Father who wrote most extensively and systematically about eschatology—the study of the end times, the Second Coming of Christ, and the life of the age to come—is St. Cyril of Alexandria.

While many Fathers touched upon these themes, St. Cyril provides a comprehensive Orthodox framework, particularly in his commentaries on the Prophets and his later festal letters.

St. Cyril of Alexandria and the "Last Day"

St. Cyril’s eschatology is deeply rooted in the Incarnation. He teaches that because the Word became flesh, our physical bodies are destined for a real, bodily resurrection. His key contributions include:

• The Resurrection of the Body: Against various heretics who suggested a purely "spiritual" resurrection, St. Cyril insisted on the restoration of the actual human body, transformed into a state of incorruption.
• The Second Coming: He describes the return of not in humility, as in the first advent, but in the full glory of His divinity to judge the living and the dead.
• The Rejection of Millenarianism: St. Cyril was instrumental in refuting "chiliasm" (the idea of a literal 1,000-year earthly reign). He taught that the Kingdom of God is spiritual and eternal, not a worldly, political kingdom.

Additional Key Figures

1. St. Athanasius the Apostolic: In his foundational work On the Incarnation, he explains that the ultimate goal of humanity is "deification" (theosis). He teaches that Christ overcame death to grant us victory over corruption, which is the ultimate eschatological hope.
2. St. Hippolytus of Rome: While an earlier Father, his work On Christ and Antichrist is one of the most detailed early treatises on the signs of the end times, the rise of the son of perdition, and the Final Judgment.
3. The Desert Fathers: Though they did not write academic books, their entire life was an "applied eschatology." They lived in constant preparation for the transition from this world to the next, viewing the monastic life as the "angelic life" practiced here on earth.

The Liturgical Perspective

In our Coptic Church, the most profound "writing" on eschatology is found in the Divine Liturgy. Every time we pray the Liturgy of St. Basil, we proclaim the eschatological reality:

"Amen. Amen. Amen. Your death, O Lord, we proclaim. Your holy resurrection and ascension into the heavens, we confess... As we also look for His second coming from the heavens, awesome and glorious."

This confirms that for the Coptic Orthodox, eschatology is not just a future event to be studied, but a present reality we experience through the Eucharist, as we wait for the "life of the age to come".
