John H. Honour, William S. Rockwell, Claude P. Samory, and Albert Pike. Of these five committee members, Pike did all the work of the committee. In 1857 Pike completed his first revision of the 4°-32° ritual, and printed 100 copies. This revision, which Mackey dubbed the "Magnum Opus", was never adopted by the Supreme Council. According to Arturo de Hoyos, 33°, the Scottish Rite's Grand Historian, the Magnum Opus became the basis for future ritual revisions. In March 1858, Pike was elected a member of the Supreme Council for the Southern Jurisdiction of the United States, and in January 1859 he became its Grand Commander. The American Civil War interrupted his work on the Scottish Rite rituals. About 1870 he, and the Supreme Council, moved to Washington, DC. In 1884 his revision of the rituals was complete. Scottish Rite Grand Archivist and Grand Historian de Hoyos created the following chart of Pike's ritual revisions: Pike also wrote lectures about all the degrees, which were published in 1871 under the title Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry. Revisions after Pike In 2000 the Southern Jurisdiction revised its ritual. The current ritual is based upon Pike's, but with some differences. Degree structure The thirty-three degrees of the Scottish Rite are conferred by several controlling bodies. The first of these is the Craft Lodge, which confers the Entered Apprentice, Fellowcraft, and Master Mason degrees. Craft lodges operate under the authority of national (or in the US, state) Grand Lodges, not the Scottish Rite. Attainment of the third Masonic degree, that of a Master Mason, represents the attainment of the highest rank in all of Masonry. Additional degrees such as those of the AASR are sometimes referred to as appendant degrees, even where the degree numbering might imply a hierarchy. They represent a lateral movement in Masonic education rather than an upward movement, and are degrees of instruction rather than rank. In 2000, the Southern Jurisdiction in the United States completed a revision of its ritual scripts. In 2004, the Northern Jurisdiction in the United States rewrote and reorganized its degrees. Further changes have occurred in 2006. The current titles of the degrees and their arrangement in the Southern Jurisdiction remains substantially unchanged from the beginning. The list of degrees for the Supreme Councils of Australia, England and Wales, and most other jurisdictions largely agrees with that of
