The title of Chaplain describes a clergy professional who is of the Chapel, or from the Chapel.  Unlike parish clergy, the ministry of the Chaplain is not focused on the life of the parish but on the life of the unit, whether that may be the military unit, hospital, prison or school.  Chaplains remain grounded in a life of prayer, worship and study, and then exercise their ministry on the deck plates, in the field, and in the daily life of their units.  Wherever chaplains go, they bear the symbols of their ministry, encouraging their shipmates and reminding them of the divine and the eternal.  When chaplains return to their prayers, they offer back to God those needs and concerns that have been shared with them, entering into the divine presence with the people on their hearts.
