Do Catholics and Mainstream Protestants believe this as well? Do Muslims think something similar -- only everyone who isn‘t Muslim will be killed by their version of Messiah? Does anyone see a problem with these ideas of Messiah?
Why were problems with the Healing Messiah 'found' by some? If One Does Well won't it Be Accepted in proclaiming the acceptable year of The Lord? The House of Cyrus did wars as kings do for their concerns. The Maccabeans had 'no' resistances, instead, in times of trouble is written. Moses and Elisha had Healings.? Elisha Healed Naaman the Assyrian Noble keeping Benjamain and the Captain of the Aram was Healed through Obedience. Tyre and Cy don as Cyrus. the new Empire in the North Territory Countries; they 'would have' repented.
No - this is not what the Bible teaches. ***** Response to additional details ****** The Bible teaches that our Messiah has already completed His mission of salvation. Various 'end times' prophecies teach that our Messiah will once more return to collect His faithful followers, most likely before the time of Great tribulation engulfs the earth. Subsequent to this period will be the final judgment of God for every human sole. Then Messiah will reign eternally as benevolent king over the righteous. I left out allot of pertinent details because it would be logistically implausible in this forum to cover every aspect of end times prophecy. But there is, to my knowledge, no prophecy stating that the Supreme Messiah will destroy anyone's life based on their unbelief. His explicit mission is to save the unrighteous. There are prophecies regarding God destroying the entire earth (including those people who have rejected His salvation). So at the final judgment, there will be an ultimate separation of the righteous from those who have refused Him. But not in the manner that your question suggests.
The Rapture theology popular among US fundamentalists is not universal. Catholics and mainstream Protestants generally don't accept the story, which was invented in the 19th century. When I was a kid in a mainstream church we were taught that Jesus would one day return to rule over a perfect world. The stuff about blood running in the streets and a vengeful Jesus killing all who opposed him was regarded as fantasies of a fringe cult which interpreted the Bible according to its own wishes.
