I don’t worry about it. People speculate on the end of the world, but no pope or bishop has ever had people out on their rooftops waiting for it.
Still, I can’t hate these poor folk. They’re poorly educated on any level, have somehow scraped up the money to do this (and I have lived in a place where I knew somebody whose husband had a “church” in his garage where he collected big bucks from about 10 little old Protestant ladies), and probably do believe what they’re saying.
That’s why they need to come back to the Church. When people go off on their own, the Devil is watching and waiting.
For amusement, some pretty stout folks have been taken in:
Saint Clement I 100
Saint Martin of Tours 400
(Antipope) Hippolytus predicted 500
Germans went completely off the rails late 900s
1000-MAY: The body of Charlemagne was disinterred on Pentecost. A legend had arisen that an emperor would rise from his sleep to fight the Antichrist.
1033 -— lots of folks
1284 (Pope Innocent III computed this date by adding 666 years onto the date the Islam was founded — not a bad guess, IMHO)
1689: Benjamin Keach, a 17th century Baptist
1792: This was the date of the end of the world calculated by some believers in the Shaker movement.
1794: Charles Wesley, one of the founders of Methodism
