You keep stuff like this in reserve to drop when these threads show up, don’t you. Congrats. You win!
there’s no “winning” or “losing” - there are facts that the pre-tribulation rapture emerged only in the early 1800s - the same time and place as Mormonism, Seventh Day Adventism Jehovah’s witnesses and Christian scientists.

You’ve noticed too; eh?
