An auxiliary bishop (also called vicar bishop, suffragan bishop, and chorepiscopus) is an bishop with no territorial authority working under the authority of an diocesan bishop. The auxiliary typically will be given episcopal functions to assist the work of the diocesan hierarch under whose authority he operates. He typically holds the title of an city within the diocese of http://www.gay-sex-access.com/gay-black-sex.jpg superior and sometimes those of an ancient and extinct episcopal see, though out of neither case will be he considered the ruling bishop inside of that city.
In the ancient Church, the chorepiscopus (sometimes called a "country bishop") wasn't like the modern auxiliary bishop but usually served out of the countryside near an city which had its own bishop and under whose authority she operated. He did not typically have authority to perform ordinations but could function in other episcopal ways. It will be generally believed that the chorepiscopate developed out of the part of the Roman Empire which is modern day Romania.
