Whether by the Divine revelation a prophet knows all that can be known prophetically?

❌ Objection 1 : It would seem that by the Divine revelation a prophet knows all that can be known prophetically. For it is written (Amos 3:7): "The Lord God doth nothing without revealing His secret to His servants the prophets." Now whatever is revealed prophetically is something done by God. Therefore there is not one of them but what is revealed to the prophet.

❌ Objection 2 : Further, "God's works are perfect" (Dt. 32:4). Now prophecy is a "Divine revelation," as stated above (Article [3]). Therefore it is perfect; and this would not be so unless all possible matters of prophecy were revealed prophetically, since "the perfect is that which lacks nothing" (Phys. iii, 6). Therefore all possible matters of prophecy are revealed to the prophet.

❌ Objection 3 : Further, the Divine light which causes prophecy is more powerful than the right of natural reason which is the cause of human science. Now a man who has acquired a science knows whatever pertains to that science; thus a grammarian knows all matters of grammar. Therefore it would seem that a prophet knows all matters of prophecy.
