“Attending at the Altar” is not among the enumerated duties of the Senior Deacon. Rather, our Ritual assigns this work to the Senior Deacon because he is conveniently close to both the Altar and the Worshipful Master. This is no basis to assert that the Senior Deacon has exclusive provenance over the Altar, however, and it is a prerogative of the Worshipful Master to direct or authorize any Brother to perform any work in the Lodge.
