What are the higher degrees in Freemasonry and their meanings?

Under the English Constitution, official Masonry is defined as consisting strictly of the three Craft degrees and the Holy Royal Arch 2. Wilmshurst argues that supplementary higher degrees are merely side-points or alternative symbolic expressions that offer no additional arcane secrets beyond the core system 2. In his view, the Holy Royal Arch serves as the climax and completion of the Master Mason degree, symbolizing total human spiritual regeneration, expressed through the interpretation "My people having obtained mercy," where the candidate's faculties are integrated into a higher order of life 2.

In the Ancient and Accepted Scottish Rite, higher degrees form an extended sequence reaching up to the 33rd degree, Sovereign Grand Inspector-General 1. These grades encompass numerical ranks such as the Grand Pontiff (19th), Knight Kadosh (30th), and Sublime Prince of the Royal Secret (32nd) 1. Degree groupings and titles vary between jurisdictions; in the United States, the Northern Masonic Jurisdiction places the 19th through 32nd grades within the Consistory, whereas the Southern Jurisdiction uses alternate naming conventions, such as omitting certain words or employing "Elu" 1. The Scottish Rite also bestows the rank of Honorary Thirty-Third upon select brethren as a reward for service, allowing attendance and limited participation without the executive powers of an active Inspector-General 1.

Additionally, certain higher or side degrees function as honorary distinctions tied to specific leadership roles rather than numerical advancement 1. In the regular lodge and chapter system, the Past Master degree is awarded to an elected Master of a Symbolic Lodge, while the Degree of High Priesthood is conferred upon an elected High Priest of a Royal Arch Chapter 1.
