Pretty sure that folks who lived in the time of those writings thought it would happen in their times.
I have heard those same sentiments from contemporary disaster survivors, LL. When interviewed on camera, some in the midst of crisis have declared to reporters, "I thought the world was ending." I wonder what causes humans in personally unprecedented circumstances to interpret them as global dissolution.
erm Yeah. Your OP said: "apocalypse (n.)
late 14c., "revelation, disclosure," from Church Latin apocalypsis "revelation," from Greek apokalyptein "uncover, disclose, reveal," from apo- "from" (see apo-) + kalyptein "to cover, conceal" (see Calypso). The Christian end-of-the-world story is part of the revelation in John of Patmos' book "Apokalypsis" (a title rendered into English as "Apocalypse" c. 1230 and "Revelations" by Wyclif c. 1380). Online Etymology Dictionary"
"Who or what is being uncovered, disclosed or revealed in the biblical apocalypse?"
I replied. There is evidence supporting my reply. Any suggestion that someone will "reincarnate" and bring about an apocalypse resulting in a judgement about "believers" and "non-believers" is supposition and conjecture without evidentiary support.
I didn't realize you were quoting the Online Etymology Dictionary, AG. Thanks for the clarification.
