The Junior Deacon for the 6013 Masonic Year is Brother Harry Patterson.
A Deacon is a junior officer in the lodge. In most jurisdictions, a lodge has two Deacons, styled Senior Deacon and Junior Deacon (though First Deacon and Second Deacon are sometimes encountered as an alternative.) The principal duties of the Senior Deacon are to conduct candidates around the Lodge and speak for them during certain ceremonies, to assist the Worshipful Master as needed and to carry messages between the Master and the Senior Warden. The office of Junior Deacon is similar in many respects to that of Senior Deacon. The principal duties of the Junior Deacon are to assist the Senior Warden, and carry messages between the two Wardens. In some jurisdictions he is also responsible for guarding the inside of the main door of the lodge and ensuring that the lodge is "tyled" (in other jurisdictions this duty is given to the Inner Guard or Inside Sentinel or Pursuivant).
