The officers of a Grand Lodge, Grand Chapter, or other Supreme Body in Freemasonry, are divided into Grand and Subordinate; the former, who are the Grand and Deputy Grand Master, the Grand Wardens and Grand Treasurer, Secretary, and Chaplain, are also sometimes called the Dignitaries. The officers of a Lodge or Chapter are divided into the Elected and the Appointed, the former in the United States of America being the Master, Wardens, Treasurer, and Secretary, while in England only the Master and Treasurer are elected.
