In late Antiquity there were too many hierarchies for comfort. How to coordinate them was not self-evident. This chapter looks at the apostolic see’s efforts to resolve a case where imperial law clashed with episcopal law, to regulate relations between the imperial and episcopal hierarchy (in which the bishop of Rome was included), and to coordinate hierarchy of command with status hierarchy. Indissolubility of marriage (papal versus imperial rulings), the ban on members of the curial class entering the clergy, and metropolitan episcopal jurisdiction are discussed.
