Ordinary Bishops Ordinaries are the bishops you usually think of. Every ordinary bishop is responsible to his metropolitan. Auxiliary Bishops Auxiliary bishops assist the ordinary in the diocese. They enjoy the full rights of any consecrated bishop, but exercise control of their diocese as subordinates of the ordinary. The titular bishopric is thus simply a title of honor, the bishopric itself usually an ancient see from the Mediterranean or Holy Land.
All auxiliary bishops are titular bishops of some such see.
Those bishops and archbishops who work in the Roman Curia hold titular sees. Coadjutors are usually only named when the diocesan bishop is in very poor health, dying, or very near retirement. Bishops Emeriti Bishops emeriti are retired bishops who have given up control of their see due to old age. A bishop emeritus still keeps the title of the bishopric as a sign of honor and respect. Organization of a Diocese A diocese is the particular Church, led by a bishop, which is the basic unit of the Hierarchy.
