A sociology professor every year begins his course on "The Family" by reading to his class a letter, from a parent, written to a government official. In the letter the parent complains that his son, once obedient and well motivated, has become involved with some weird new religious cult. The father complains that the cult has taken over the boy's life, has forced him to forsake all of his old friends, and has turned him against his family.

After reading the letter, the professor asks the class to speculate what the father is talking about. Almost without exception, the class immediately assumes that the subject of the letter is a child mixed up with the "Moonies," or some other controversial group. After the class puts out all of the possible conclusions they can think of, the professor surprises them by revealing that the letter, was written by a third century father in Rome, the governor of his province, complaining about this weird religious group called "The Christians."
