text: No Christian denomination has had any "prophets" since John the Baptist, that's precisely the point. Even Luther, Calvin, etc. are not considered prophets.
  
  The Mormons claim there was a prophet in the 19th century who revealed a whole new set of laws, revelations, etc., that updates and supplements the Bible in radical ways, the way Christians say J-C and the New Testament updated and supplemented the Jewish Bible in a radical way. That's different from just claiming you understand the original Bible better than some other denomination. Radical enough that that makes Christians Christians, not a sect of Judaism, although in some ways they are and some small sects consider themselves so...
  
  But if Christians are Christians and not a sect of Judaism in any meaningful sense, then Mormons are Mormons, not a sect of Christianity in any meaningful sense.
