Les évêques auxiliaires ne dirigent pas directement le diocèse mais agissent sous la direction de l'évêque diocésain.
Evêques titulaires=== Bishops who are assigned a title of ancient dioceses that no longer function are called Titular Bishops. The Diocese of Sourozh, the diocese of the Russian Orthodox Church, Moscow Patriarchate, in Great Britain and Ireland, is an example. However, generally, titular bishops are auxiliary bishops.
