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
LOL! Well, maybe his calculations were off...but Islam, a syncretist fraud that is the anti-Christianity and anti-Judaism, will most likely have something to do with it.
Still, we know not the hour...
