Traditionally the Chaplain has been regarded as the "Friend and Advisor of All", irrespective of rank, and acts as an advocate for those of any faith or none. Chaplains are responsible for carrying out chapel services, confirmations, marriages and funerals, counseling the anxious, visiting the sick, and absolving the penitent. While a Chaplain holds an officer's rank, tradition dictates that the Chaplain is treated at all times as though he were of the rank of the person addressing him or her, thus he or she neither accepts nor returns salutes, and has access to every mess and berthing aboard.
