Essential Texts for Understanding Early Eschatology

Start with these specific passages to understand the key positions

For Understanding Early Chiliasm

  • Justin Martyr, Dialogue with Trypho, chapters 80-81: "I and others who are right-minded Christians know there will be a resurrection of the flesh for a thousand years in Jerusalem"
  • Irenaeus, Against Heresies 5.32-36: The most theological defense of the literal millennium
  • Epistle of Barnabas, chapter 15: The 6000+1000 year calculation

For Understanding the "Spiritual Israel" Innovation

  • Justin Martyr, Dialogue with Trypho 11.5: "We are the true spiritual Israel" (first occurrence of this phrase)
  • Compare with Paul's Romans 9-11: Note that Paul never uses this terminology

For Understanding the Shift to Amillennialism

  • Origen, De Principiis 2.11.2-3: Philosophical arguments against literal interpretation
  • Augustine, City of God 20.7-9: The millennium as the church age
  • Eusebius, Ecclesiastical History 3.39: Dismissal of Papias and early chiliasm

For Understanding Tribulation Views

  • Irenaeus, Against Heresies 5.29.1-2: The resurrection occurs "when Antichrist shall have devastated all things"
  • Hippolytus, Treatise on Christ and Antichrist 60-65: Saints persecuted by Antichrist until Christ destroys him
  • The Shepherd of Hermas, Vision 4: Complex view of past and future tribulation
  • Pseudo-Ephraem, Sermon on End Times: The controversial pre-trib text (if authentic)
