II.6. Chorbishops
(1) Chorbishops, that is, vicars of the bishops, according to what the canons themselves testify, were instituted according to the example of the seventy elders as co-priests for the solicitude of the poor. These, constituted in towns and villages, govern churches committed to them, having permission to constitute lectors, subdeacons, and exorcists. However, they dare not ordain presbyters or deacons against the conscience of the bishops in whose region they are known to preside. For these are ordained by the bishop alone of the city that they adjoin.
