Every Masonic Lodge elects certain officers to execute the necessary functions of the lodge’s work. The Worshipful Master (essentially the lodge President) is always an elected officer. Most jurisdictions will also elect the Senior and Junior Wardens (Vice Presidents), the Secretary and the Treasurer. All lodges will have a Tyler, or Tiler, (who guards the door to the lodge room while the lodge is in session), sometimes elected and sometimes appointed by the Master. In addition to these elected officers, lodges will have various appointed officers – such as Deacons, Stewards, and a Chaplain (appointed to lead a non-denominational prayer at the convocation of meetings or activities – often, but not necessarily, a clergyman). The specific offices and their functions vary between jurisdictions.
Many offices are replicated at the Provincial and Grand Lodge levels with the addition of the word ‘Grand’ somewhere in the title. For example, where every lodge has a ‘Junior Warden’, Grand Lodges have a ‘Grand Junior Warden’ (or sometimes ‘Junior Grand Warden’). Additionally, there are a number of offices that exist only at the Grand Lodge level.
