Whether the degrees of prophecy change as time goes on?

Objections

Objection 1 : It would seem that the degrees of prophecy change as time goes on. For prophecy is directed to the knowledge of Divine things, as stated above (Article [2]). Now according to Gregory (Hom. in Ezech.), "knowledge of God went on increasing as time went on." Therefore degrees of prophecy should be distinguished according to the process of time.
Objection 2 : Further, prophetic revelation is conveyed by God speaking to man; while the prophets declared both in words and in writing the things revealed to them. Now it is written (1 Kgs. 3:1) that before the time of Samuel "the word of the Lord was precious," i.e. rare; and yet afterwards it was delivered to many. In like manner the books of the prophets do not appear to have been written before the time of Isaias, to whom it was said (Is. 8:1): "Take thee a great book and write in it with a man's pen," after which many prophets wrote their prophecies. Therefore it would seem that in course of time the degree of prophecy made progress.
Objection 3 : Further, our Lord said (Mt. 11:13): "The prophets and the law prophesied until John"; and afterwards the gift of prophecy was in Christ's disciples in a much more excellent manner than in the prophets of old, according to Eph. 3:5, "In other generations" the mystery of Christ "was not known to the sons of men, as it is now revealed to His holy apostles and prophets in the Spirit." Therefore it would seem that in course of time the degree of prophecy advanced.
