The senior officer of a Masonic Lodge is the Master, normally addressed and referred to as the "Worshipful Master". The word "Worshipful" does not suggest that the Master is worshiped, but is used in its original meaning, "worthy of respect". The Worshipful Master conducts all of the business of his lodge, and presides over ritual and ceremonies.
The office of Worshipful Master is the highest honor to which a lodge may appoint any of its members. The office is filled annually by election.
