A Corporation Sole is a type of special organization, kind of like a club, that is only given to certain religious leaders so they can do their work in a special way. This means that instead of one person, like you or I, being in charge of it, there is only one special person who can control it. Think of it like a special hat that only certain people can wear to do their jobs. When that person who wears the hat is no longer around, someone else gets to wear the hat and take over the special job. This helps the religious leader to have more control over the organization, and to make sure their work is done the way they want it done.
