Were you surprised to learn that the Greek term (αποκ?λυψη) apokalypsi had a different meaning than you had been taught? Apocalypse as a disclosure of knowledge or a revelation is foreign to our modern idea of apocalypse. In religious contexts it is usually a disclosure of something hidden, a vision of heavenly secrets that can make sense of earthly realities. Does this change your idea of a humanity ending disaster? How do you think humanity might come to a demise?
