The Holy Royal Arch Knight Templar Priests is an honorary and invitational organization with membership limitations and cannot be applied for. Members are selected and extended invitations on the basis of outstanding performance as a Commander of a Commandery of Knights Templar. The order has historic roots in England that trace back to 1786, with references back to 1686, the traditional year of revival. The "Priestly Order" was referred to within the ceremonies of "The High Knights Templar" in Ireland in 1755. There are records of the conferral of this Order in the United States during the 1800's but the authority is unknown. The Grand College of America, Holy Royal Arch Knight Templar Priests was formed in the United States in 1931. The limit of Regular Members in a Tabernacle is 33. The number of Tabernacles in a state is dependent on the number of active Commanderies in each state.

To become a member of this organization, you must first become a member of the Blue Lodge.  In this case, that would be Oshkosh Lodge #27.
