A1 Whether the priest of the Law had the keys?

A2 Whether Christ had the keys?

A3 Whether priests alone have the keys?

A4 Whether holy men who are not priests have the keys or their use?

A5 Whether wicked priests have the effective use of the keys?

A6 Whether those who are schismatics, heretics, excommunicate, suspended or degraded, have the use of the keys?
