Why is the Royal Arch Chapter said to be attached to a lodge?

Under the English Constitution, every Royal Arch Chapter must be attached to a Craft Lodge and take the same number as that Lodge, and often its name, as part of the structure connecting the Royal Arch to Craft Masonry (suffolkfreemasons.org.uk).

This arrangement reflects the historical and constitutional regulations governing the Order. The regulations following the 1813 Union provided that every Chapter must be attached to a Craft Lodge, taking its number and seniority on the register (grandlodge.org.nz). This was reaffirmed by the laws and regulations approved by the Grand Chapter in May 1817, which confirmed that every Chapter had to be attached to a Craft Lodge and that no Lodge could form a Chapter without obtaining a Charter to attach to its Craft Warrant (aim25.com).

The concept of a Chapter being closely bound to a Lodge also existed prior to these formal English codifications. In early Canadian practice, for instance, an early member was charged in 1806 with un-Masonic conduct for attempting to separate a Chapter from the body of its attached Craft Lodge's number 2. Historically, prerequisites such as the Past Master's qualification were conferred within the Master's lodge to which the Chapter was attached 2.

This structural attachment emphasizes that the Royal Arch is not a separate entity, but forms an integral completing part of the Masonic legend 1.

The relationship between Craft Freemasonry and the Royal Arch in England is rooted in the 1813 Act of Union between the two competing Grand Lodges (the "Ancients" and the "Moderns") 21. Article II of the Articles of Union declared that "pure Antient Masonry" consists of three degrees—Entered Apprentice, Fellow Craft, and Master Mason—including the Supreme Order of the Holy Royal Arch 21. This declaration establishing the link between Craft Freemasonry and the Royal Arch stands at the front of the Book of Constitutions according to the United Grand Lodge of England.

Historically, the Royal Arch was considered by scholars such as Dr. W. J. Chetwode Crawley to be not a separate entity, but the completing part of a Masonic legend and a constituent element of the Third Degree, without which the Masonic symbolic structure would be left incomplete 1. In earlier English practice, eligibility for the Royal Arch was restricted to Past Masters of a Craft Lodge, which led to the creation of ceremonial mechanisms such as "Passing the Chair" for those who had not actually served as Master 1. Under modern English governance, any Master Mason of at least four weeks' standing in a Lodge under the United Grand Lodge of England (UGLE), or a Grand Lodge recognized by it, is eligible for admission into an English Royal Arch Chapter according to UGLE regulations.

Administratively, the Craft degrees are governed by UGLE, while the Royal Arch is governed by the Supreme Grand Chapter of England. Although the Supreme Grand Chapter operates as a separate organization with its own administrative structure and finances, its operation is closely linked to UGLE, and its administration has been entrusted to UGLE. Joint governance is maintained at the highest level: the Grand Master of UGLE automatically serves as the First Grand Principal of the Supreme Grand Chapter; the Pro Grand Master in the Craft serves as the Pro First Grand Principal in the Royal Arch; and the Grand Secretary of UGLE automatically holds the office of Grand Scribe Ezra (Grand Secretary) in the Supreme Grand Chapter.

Eligibility for a Master Mason seeking to become a Companion originally rested on having served as a Master of a Lodge 1. In England, this restriction was formerly circumvented by the practice of "Passing the Chair" to confer a form of Past Master status on brethren who had not served in that office, until the qualification was altered so that any Master Mason of four weeks' standing became eligible for Exaltation 1.

At present, the prime qualification for admission into the Order is to be a Master Mason of at least four weeks standing in a Lodge under the United Grand Lodge of England, or a Lodge under a Grand Lodge recognised by it, as stated by the Supreme Grand Chapter of England. Members meet in Chapters under the Supreme Grand Chapter of England, as noted by the United Grand Lodge of England. A Master Mason officially becomes a Companion through the Ceremony of Exaltation.
