abbey nullius

Latin: of no (diocese)

A territory belonging to no diocese, i.e., separated and distinct by proper boundaries from surrounding dioceses. It is ruled by a prelate, who exercises active jurisdiction over the clergy and people living in his territory. The abbies of Saint Peter, Muenster, Saskatchewan, the Belmont Abbey in North Carolina, New Norcia in Australia, and Lindi in Senegal were abbies nullius, but their jurisdiction has been suppressed and made part of a diocese.
