What are the duties of a Master after being elected?

Upon assuming office, a Worshipful Master immediately exercises his authority by appointing and investing his officers, beginning with the Senior and Junior Wardens 1. He is responsible for directing their duties, charging the Senior Warden with assisting in governing the lodge and the Junior Warden with overseeing the examination of visitors and the introduction of candidates 1.

The Master holds sole authority over the appointment of all lodge committees, serving as an ex officio member of each 2. This includes selecting the committees responsible for investigating petitioners and those tasked with examining visiting brethren, as he bears ultimate accountability to the Grand Lodge for the lodge's conduct and security 2. In line with this responsibility, he holds the power to admit or exclude visitors, governed by Grand Lodge regulations and the pledges of his installation 2. It is also generally his exclusive prerogative to issue a summons to the membership 2.

Administratively, the Master is charged with ensuring the proper care, presence, and preservation of the lodge's records and historical books upon taking office 3. Throughout his tenure, he governs the lodge with broad executive authority, bounded by the edicts of the Grand Lodge, the Constitutions, and the ancient landmarks and usages 2.
