We must now consider the ministers and the use of the keys: under which head there are six points of inquiry:
A Whether the priest of the Law had the keys?
A Whether Christ had the keys?
A Whether priests alone have the keys?
A Whether holy men who are not priests have the keys or their use?
A Whether wicked priests have the effective use of the keys?
A Whether those who are schismatics, heretics, excommunicate, suspended or degraded, have the use of the keys?
