Magister Disciplinae
Charles Buck Theological Dictionary [1]
Or Master Of Discipline the appellation of a certain ecclesiastical officer in the ancient Christian church. It was a custom in some places, particularly in Spain, in the time of the Gothic kings, about the end of the fifth century, for parents to dedicate their children very young to the service of the church. For this purpose they were taken into the bishop's family, and educated under him by some grave and discreet person whom the bishop deputed for that purpose, and set over them, by the name of Presbyter or Magister Disciplinae, whose chief business it was to inspect their behaviour, and instruct them in the rules and discipline of the church.
