Karaite
4) Some Russian Christians -including some of the western groups of the Karaite people- took many ideas from Karaite Judaism but they did not completely give up on Jesus. They became Russian Sabbatarians. They are also called Russian Karaites and Karaite Sabbatarians but there is a big argument about why they are called Karaite. Is it because of their religion? Or is it because some of them descended from the Karaite people or Qaraite people? It seems impossible to know.
