The officers of a Grand Lodge may be divided into two classes, essential and accidental, or, as they are more usually called, Grand and Subordinate. The former of these classes are, as the name imports, essential to the composition of a Grand Lodge and are to be found in every jurisdiction, having existed from the earliest times. They are the Grand and Deputy Grand Masters, the Grand Wardens, Grand Treasurer and Grand Secretary. The Grand Chaplain is also enumerated among the Grand Officers, but the office is of comparatively modern date.
The subordinate officers of a Grand Lodge consist of the Deacons, Marshal, Pursuivant, or Sword-Bearer, Stewards and others, whose titles and duties vary in different jurisdictions. I shall devote a separate section to the consideration of the duties of each and prerogatives of these officers.
