Whether Prophecy Pertains to Knowledge?
Objection 1: It would seem that prophecy does not pertain to knowledge. For it is written (Ecclus. 48:14) that after death the body of Eliseus prophesied, and further on (Ecclus. 49:18) it is said of Joseph that "his bones were visited, and after death they prophesied." Now no knowledge remains in the body or in the bones after death. Therefore prophecy does not pertain to knowledge.
Obj. 2: Further, it is written (1 Cor. 14:3): "He that prophesieth, speaketh to men unto edification." Now speech is not knowledge itself, but its effect. Therefore it would seem that prophecy does not pertain to knowledge.
Obj. 3: Further, every cognitive perfection excludes folly and madness. Yet both of these are consistent with prophecy; for it is written (Osee 9:7): "Know ye, O Israel, that the prophet was foolish and mad [*Vulg.: 'the spiritual man was mad']." Therefore prophecy is not a cognitive perfection.
Obj. 4: Further, just as revelation regards the intellect, so inspiration regards, apparently, the affections, since it denotes a kind of motion. Now prophecy is described as "inspiration" or "revelation," according to Cassiodorus [*Prolog. super Psalt. i]. Therefore it would seem that prophecy does not pertain to the intellect more than to the affections.
On the contrary, It is written (1 Kings 9:9): "For he that is now called a prophet, in time past was called a seer." Now sight pertains to knowledge. Therefore prophecy pertains to knowledge.
I answer that, Prophecy first and chiefly consists in knowledge, because, to wit, prophets know things that are far (procul) removed from man's knowledge. Wherefore they may be said to take their name from phanos, "apparition," because things appear to them from afar. Wherefore, as Isidore states (Etym. vii, 8), "in the Old Testament, they were called Seers, because they saw what others saw not, and surveyed things hidden in mystery." Hence among heathen nations they were known as vates, "on account of their power of mind (vi mentis)," [*The Latin vates is from the Greek phates, and may be rendered "soothsayer">[ (ibid. viii, 7).
Since, however, it is written (1 Cor. 12:7): "The manifestation of the Spirit is given to every man unto profit," and further on (1 Cor. 14:12): "Seek to abound unto the edification of the Church," it follows that prophecy consists secondarily in speech, in so far as the prophets declare for the instruction of others, the things they know through being taught of God, according to the saying of Isa. 21:10, "That which I have heard of the Lord of hosts, the God of Israel, I have declared unto you." Accordingly, as Isidore says (Etym. viii, 7), "prophets" may be described as praefatores (foretellers), "because they tell from afar (porro fantur)," that is, speak from a distance, "and foretell the truth about things to come."
Now those things above human ken which are revealed by God cannot be confirmed by human reason, which they surpass as regards the operation of the Divine power, according to Mk. 16:20, "They . . . preached everywhere, the Lord working withal and confirming the word with signs that followed." Hence, thirdly, prophecy is concerned with the working of miracles, as a kind of confirmation of the prophetic utterances. Wherefore it is written (Deut. 34:10, 11): "There arose no more a prophet in Israel like unto Moses, whom the Lord knew face to face, in all the signs and wonders."
Reply Obj. 1: These passages speak of prophecy in reference to the third point just mentioned, which regards the proof of prophecy.
