Until that time each congregation of Bible Students in the world made its own decisions, although they all studied Russell's books and followed his teachings. But Rutherford decided they should all have exactly the same set of beliefs and run their congregations the same way. He told them they had to obey what the Watch Tower Society's New York headquarters told them. A director was put into each congregation, and a year later all members were told to write out a report each week of what public preaching they had done. At an international meeting held at Cedar Point, Ohio, in September 1922, Rutherford began teaching that the Bible Students' most important job was to teach people about the Bible by visiting them at their homes. Watch Tower Society books began using the name "Jehovah" much more often when writing about God, and in 1931 Rutherford decided the religion would be called Jehovah's witnesses.
