Whether the priest of the Law had the keys?

Objections

Objection 1 : It would seem that the priests of the Law had the keys. For the possession of the keys results from having orders. But they had orders since they were called priests. Therefore the priests of the Law had the keys.
Objection 2 : Further, as the Master states (Sent. iv, D, 18), there are two keys, knowledge of discretion, and power of judgment. But the priests of the Law had authority for both of these: therefore they had the keys.
Objection 3 : Further, the priests of the Law had some power over the rest of the people, which power was not temporal, else the kingly power would not have differed from the priestly power. Therefore it was a spiritual power; and this is the key. Therefore they had the key.
