There are billboards popping up all across the nation warning that Judgement Day is coming later this year. May 21 specifically. They are the idea of Harold Camping of Family Radio based in Oakland California. They're being met with a great deal of skepticism. Camping's been wrong before.
"[A]ll of the local churches and congregations contacted for this article agree, ‘... of that day and hour knoweth no man’ (Matthew 24:36). It did not matter if they were Episcopalian, Catholic, Presbyterian, Methodist, Baptist or a nondenominational Bible church.
‘As Christians, we believe that on Judgment Day at the end of the world, Christ will come in glory to achieve the definitive triumph of good over evil and to judge the living and the dead,’ Catholic Diocese of Wilmington spokesman Bob Krebs said. ‘The Bible tells us, ‘… Be watchful! Be alert! You do not know when the time will come’ (Mark 13:32-33).’
Camping expects to hear that from the churches, which he has characterized as spiritually dead since 1988 – the so-called end of the church age."
