Origen

(tom. xxviii. c. 12.) Not every one that prophesieth is a prophet; as not every one that does a just action is just, he, for example, that does one for vainglory. Caiaphas prophesied without being a prophet, as did Balaam. Perhaps some will deny that Caiaphas prophesied by the Holy Spirit, on the ground that evil spirits may bear witness to Christ, as the one in Luke, who says, I know Thee who Thou art, the Holy One of God; (Luke 4:34) the intention of Caiaphas too being not to induce his hearers to believe on Him, but to excite them to kill Him. (c. 14.). It is expedient for us. Is this part of his prophecy true or false? If it is true, then those who contended against Jesus in the council, since Jesus died for the people, and they participate in the advantage of His death, are saved. This you say is absurd; and thence argue that the prophecy is false, and, if false, not dictated by the Holy Spirit, since the Holy Spirit does not lie. On the other side it is argued, for the truth of the prophecy, that these words only meant that He by the grace of God should taste death for all men; (Heb. 2:9) that He is the Saviour of all men, specially of them that believe. (1 Tim. 4:10) And in the same way the former part of the speech, Ye know nothing at all, is made out to be an assertion of the truth. They knew nothing of Jesus, who did not know that He was truth, wisdom, justice, and peace. And again, That one MAN. should die for the people. It was as man that He died for the people: in so far as He is the image of the invisible God, He was incapable of death. And He died for the people, in that He took upon Himself, made away with, blotted out the sins of the whole world. (c. 15.). And this spake he not of himself. Hence we see, what men say sometimes proceeds from themselves, sometimes from the influence of some power upon them. In the latter case though they may not be taken quite out of themselves, and in a certain sense go along with their own words, yet they do not go along with the meaning of them. Thus Caiaphas says nothing of himself; and therefore does not interpret his own prophcey, because he does not understand it. Thus Paul too speaks of some teachers of the law, who understand neither what they say, nor whereof they affirm. (1 Tim. 1:7)
