Perhaps our fascination with the eschaton – the end of the world – is because it is the only corner of our religious life where the mysterium tremendum – the “wholly other” – still lives. Worship, banal and jingly, and preaching, thin and familiar, has left the religious mind cold, dark, explainable, predictable, candid. The only place where the fire of mystery still burns brightly is in the uncanny images of Revelation. John’s Apocalypse recounts the terrifying future when that which is outside all categories descends on a world of categories. The only rapturous experience left in religion is the Rapture.
