What is order of scarlet cord?

Qualification for membership in the Ancient and Masonic Order of the Scarlet Cord requires being a subscribing Prince in the Order of the Secret Monitor. The Order descends from the Royal Order of Knights of the Scarlet Cord, which was developed in the British Isles in 1889 using rituals derived from eighteenth-century documents in the Amsterdam Masonic archives, as Mark Masons' Hall records. Historically, degrees of the Scarlet Cord were conferred under the auspices of the Grand Council of the Secret Monitor 1.

After the original body ceased working in 1929, the Order was revived and inaugurated as a separate sovereign body at Freemasons' Hall on 21 July 2010, as Mark Masons' Hall notes. Its ceremonial system consists of six grades: Ostiarius, Lector, Fellow, Councillor, Keeper of the Hidden Secret, and Prince of Jerusalem. The rituals of these grades draw upon Old Testament history, beginning with the period of Joshua, the fall of Jericho, and the story of Rahab, as Mark Masons' Hall states.
