What is the role of the Worshipful Master in relation to the three columns?

The Worshipful Master represents the Ionic column of Wisdom, positioned in the East to govern, guide, and instruct the lodge, as the United Grand Lodge of England states. Within this symbolic triad of principal officers, the Master's column of Wisdom is joined by the Senior Warden representing Strength through the Doric column, and the Junior Warden representing Beauty through the Corinthian column, as an article on the Grand Lodge of British Columbia and Yukon website explains.

Together, these three columns symbolize the pillars supporting the lodge. While the Senior and Junior Wardens employ replicas of their respective columns—raised or prostrate—to mark whether the Craft is at labor or refreshment 1, the Worshipful Master’s association with Wisdom centralizes his role to rule the lodge, direct its labor, and maintain order among the brethren 1.
