Freemasonry is the oldest and largest fraternity in existence. It is dedicated to the Brotherhood of Man. Although of a religious nature, Freemasonry is not a religion. Rather, it is a place where men of all creeds can meet and work on the great truths of peaceful human interaction that are common to all religions.

The organization of Freemasonry is based on a system of Grand Lodges, each sovereign within its own state or territory. There is no central authority governing all Grand Lodges. However, to be acknowledged by others, acceptable traditions, standards and practices must be maintained. Since the year 2000, Mt Juneau-Gastineaux Lodge No. 21 has been a member of the Grand Lodge of Alaska.
