Why is the Royal Arch called a supreme degree?

Designation of the Royal Arch as a supreme degree stems from both its constitutional status in historical Masonic regulations and its spiritual role as the completion of the Masonic system.

In the historical drafting of the 1813 Act of Union between the Ancients and Moderns, an initial proposed draft described pure Antient Masonry as four degrees, featuring the "Supreme Degree of the Holy Royal Arch," prior to the final text adopting the phrase "Supreme Order" of the Holy Royal Arch (the United Grand Lodge of England states). This terminology reflected earlier General Grand Chapter records, which asserted that regular Masters of the Royal Arch alone possessed the supreme degree of the Craft (Quatuor Coronati Lodge records). The finalized 1813 Articles of Union formally declared that pure Antient Masonry consists of three degrees, including the Supreme Order of the Holy Royal Arch 2.

Philosophically, the Royal Arch is described as a supreme degree because it represents the climax and completion of the Masonic process 1. Rather than offering elementary instruction, it moves upon a high level of thought dealing with the higher reaches of human consciousness and understanding 1. The preliminary Craft work is regarded as unfinished without the culmination offered in the Royal Arch 1, which outlines the full process of human regeneration and integration into a higher order of life 1.

Exaltation is the ceremony through which a Master Mason becomes a member of the Royal Arch, enabling candidates to complete their journey in Pure Antient Masonry as a Companion ( the United Grand Lodge of England states, the Supreme Grand Chapter states ). Historically in England, candidates were required to be Past Masters to be eligible for exaltation, though regulations later enabled any Master Mason of four weeks' standing to be exalted 3.

Symbolically, exaltation represents the climax and fulfilment of the Third Degree, extending the process of symbolic death and revival into apotheosis 1. Where the Master Mason degree dramatizes revival into newness of life, the ceremony of exaltation represents ascension into an expanded, illimitable level of consciousness 1. Mystically, it sacramentally portrays the soul's escape from the captivity of the material world, passing through the veils of form into spiritual liberty 1. It signifies an efflorescence of human intelligence brought into conscious union with the Universal Mind 1.

Differences in physical arrangement, governance, officer structure, and terminology distinguish a Royal Arch Chapter from a Craft lodge. In decor and furniture, the predominating colour of a lodge room is blue, whereas a Chapter room is decorated in red 3. While a lodge features a single pedestal on the eastern dais for the presiding Master, a Chapter room provides three pedestals on its eastern dais to accommodate the Grand Council, as well as a tabernacle structure or veils 3.

Leadership and administrative structures also contrast significantly between the two bodies. A Craft lodge is presided over by a Worshipful Master, whereas a Royal Arch Chapter is headed by a trio of Principals—the First, Second, and Third Principals—who exercise conjoint leadership ( the Grand Lodge of India states ). The officer structure of a Chapter comprises nine officers arranged in three triads around a central sacred symbol on the floor, contrasting with the traditional seven officers of a lodge 1. The administrative recording officer is titled the Secretary in a lodge, but is designated as Scribe E, or Scribe Ezra, in a Chapter ( the Grand Lodge of India states ).

Terminology and regalia further set the working apart. Members of a lodge are styled as brethren, while members in a Chapter are known as Companions ( the Grand Lodge of India states ). The ceremony of admission into a lodge is an initiation, whereas admission into a Chapter is termed an exaltation ( the United Grand Lodge of England states ). In addition, past presiding officers wear Past Master's jewels in a Craft lodge, whereas Past Z jewels are worn within a Chapter ( the Grand Lodge of India states ).
