What is the purpose of allied degrees in Freemasonry?

The purpose of allied degrees in Freemasonry is to provide additional opportunities for Masonic education and fellowship beyond the initial three degrees of Craft Masonry. These degrees, such as St. Lawrence the Martyr, Knight of Constantinople, and Red Cross of Babylon, serve to deepen the understanding of Masonic principles and history, while also fostering mutual support among members. As noted by Robert Lomas, the allied degrees are designed to extend the Craft system and offer practical benefits, emphasizing mutual help and support among Masons. They also allow members to explore further the rich symbolism and teachings of Freemasonry, enhancing their spiritual and moral development.
