As we reported recently, a new prophecy by Christian numerologists suggests that the world will come to an end on Sept. 23. But it’s the details of this totally bonkers end-times theory that will really amaze you, and it has to do with a mysterious planet and Jesus Christ’s second coming on Earth.

Christian numerologist David Meade believes that Luke 21:25-26 indicate that the recent solar eclipse and Hurricane Harvey are signs of something much more sinister on the horizon. Specifically, that a “Planet X” will zoom past Earth and cause volcanoes and earthquakes and destruction, ushering in the end times and the second coming of Christ.

The verses in question say the following “25: There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 26: Men’s hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.”

So what’s at the heart of this crazy theory? It’s called the Nibiru cataclysm, and it’s been around for a while. It’s the theory that there will be a disastrous encounter between a large planetary object and Earth at some point in the 21st century. This theory was first put forward in 1995 by a woman who claimed to have the ability to receive messages from extraterrestrials through a brain implant. Apparently, some Christian numerologists have taken this theory and given it a Christian spin.
