Fiend God
It is worse. After the first fiasco, there were a whole string of subsequent failures. So bad that these days they refuse any and all specific dates.
One might think that such a truck of fail would be a death knell for such a so called faith, but it isn't. Plenty of SDA still about, still doorstepping people.
Jesus said he'd be back before the then-current generation was out. That rather blatant bit of fail didn't deter Christians.
