That’s been tried before many times. In particular, there was a group called Heaven’s Gate, that expected the world to end back in 1997, lead by Marshall Applewhite.
They expected an Amagedeon type change to the world with the approach of a comet called Hale-Bopp.
The coordinated suicide of 39 group members was considered by them to be a “Graduation Ceremony”, as one departs their earth bound existence.
I recall the news storied vividly.
Art Bell covered both this group and the Hale-Bopp comet’s approach in detail.
I knew a fellow who got caught up in the UFO Religion Groups on the Internet...Nobody could believe he fell for that stuff but he did and it totally screwed up his mind ..... he did not come away from it unscathed.
It’s true the enemy of mens souls goes about like a roaring lion seeking who he may devour. That stuff darn near came close to destroying the guy....lost his wife, kid and family following those idiots!
I remember that. Big comet was in the north sky for a few nights. Weirdos drank poisoned grape “koolaid” and cut their nuts off I think.
I came into full Communion with the Catholic Church Easter of 1997. As an astronomy buff, it was awesome as we processed into the church behind the Paschal Candle lit with the newly blessed Easter Fire to turn and see Hale-Bopp hanging in the sky.
That HaleBopp Cult
Was 20 miles north
of where I sit now.
I never got invited.
