This is one of the most important offices in the Grand Lodge and should always be occupied by a Brother of intelligence and education, whose abilities may reflect honor on the institution of which he is the accredited public organ. The office was established in the year 1723, during the Grand Mastership of the Duke of Wharton, previous to which time the duties appear to have been discharged by the Grand Wardens.
The Grand Secretary not only records the proceedings of the Grand Lodge, but conducts its correspondence and is the medium through whom all applications on Masonic subjects are to be made to the Grand Master, or the Grand Lodge.
According to the regulations of the Grand Lodges of England, New York and South Carolina, the Grand Secretary may appoint an assistant, who is not, however, by virtue of such appointment, a member of the Grand Lodge. The same privilege is also extended in South Carolina to the Grand Treasurer.
