Presbyterianism is a kind of Protestant Christianity. It was started in Scotland by John Knox during the 16th century. It became powerful in England during the Civil War. Today there are Presbyterian churches across the world.
Presbyterians (followers of Presbyterianism) believe that the Bible is the most important thing in their church because it was given to humans by God and has no errors in it. They believe that God has control over everything and has chosen to make some people follow Jesus Christ but not others, and that only followers of Jesus may get into heaven. (See Calvinism)
