What are the key teachings of the Holy Royal Arch?

Wilmshurst interprets the Holy Royal Arch as the sacramental representation of the final stage of spiritual regeneration, portraying the soul's passage from captivity in the temporal world to spiritual liberty 1. In his reading, the Order marks the necessary completion of the Craft work, providing the spiritual culmination toward which the discipline and purification of the preliminary degrees lead 1. Rather than memorializing outward historical structures, the degree symbolizes the re-erection of the disordered temple of the human soul 1.

Within this mystical framework, the ritual personages represent distinct internal spiritual and psychological principles:

The Three Principals personify the spiritual pole in man in its threefold aspects of holiness, royal supremacy, and functional power 1. Zerubbabel acts as the central coordinating majesty, while Haggai signifies the passive, self-contemplative nature of the spirit, and Joshua represents the active executive power functioning to redeem the lower nature 1.

The Sojourners represent the human Ego or personality acting on the physical plane, distributed into the directive principal will, the passive intuitional subconsciousness, and the active practical intelligence 1.

The Scribes, Ezra and Nehemiah, personify progressive stages of inner self-reconstruction 1. Nehemiah symbolizes the initial labor of rebuilding the soul's defenses while resisting worldly distractions, whereas Ezra signifies an advanced stage of spiritual progress toward full illumination 1. Together with the Janitor, the Scribes represent the mediating medium connecting the spiritual and bodily poles of man 1.
