A Grand Council of the Allied Masonic Degrees was established in the late 1870s, with headquarters at Mark Masons Hall.
Following an understanding reached in 1931, the Grand Council has been responsible for five Masonic Degrees, namely:
St Lawrence the Martyr. This teaches a lesson of fortitude arising from the sufferings of St Lawrence and is the first degree to be taken by all candidates. The remaining four may be taken in any sequence.
- Knights of Constantinople. Refers to the legendary Constantine and preaches the virtues of humility and equality.
- Red Cross of Babylon. Associated with the Royal Arch, it deals with Zerubbabel under the reigns of Cyrus and Darius.
- Grand Tilers of Solomon. Warns of the great danger of carelessness and of hasty judgment and teaches the importance of careful tiling.
- Grand High Priest. Deals with the Blessing of Abraham and the consecration of Aaron.
Candidates for the Order must be both Mark Master Masons and Royal Arch Companions. When he has passed through all five degrees, the candidate qualifies for the pentagonal Breast Jewel of the Order.
