Old believers are a group of people who believed in a certain form of religion that was practiced a long time ago. These people believe that the way they practice their religion is the correct way and they don't want to change it.
A long time ago, there was a leader in the church who wanted to change the way people practiced their religion. Some people didn't like these changes and wanted to keep practicing their religion the way it had always been done. So, they formed a separate group and continued to practice the old ways.
These old believers believe that the way they practice their religion is the right way and they don't want to change it. They believe that changing the way they practice their religion is a bad thing and that it goes against what their religion is all about.
Even though the old believers have been around for a long time, there are still some people who practice this way of religion today. They are very dedicated to their beliefs and they take them very seriously.
