At this point, an interesting question arises, which, however, can never be answered with any certainty. Did Paul ever see Jesus before the crucifixion? In the light of what has just been established about the outline of Paul's life, an affirmative answer might seem to be natural. Paul was in Jerusalem both before and after the public ministry of Jesus—before it when he was being "brought up" in Jerusalem, and after it when he was engaged in persecution of the Jerusalem Church. Where was he during the interval? Where was he on those occasions when Jesus visited Jerusalem—especially at the time of that last Passover? If he was in Jerusalem, it seems probable that he would have seen the great prophet, whose coming caused such a stir among the people. And that he was in the city at Passover time would seem natural in view of his devotion to the Law. But the matter is by no means certain. He may have returned to Tarsus, in the manner which has just been suggested.
The question could only be decided on the basis of actual testimony either in Acts or in the Epistles. One verse has often been thought to provide such testimony. In 2 Cor. v. 16, Paul says, "Even if we have known Christ after the flesh, yet now we know him so no longer." Knowledge of Christ after the flesh can only mean, it is said, knowledge of Him by the ordinary use of the senses, in the manner in which one man in ordinary human intercourse knows another. That kind of knowledge, Paul says, has ceased to have significance for the Christian in his relation to other men; it has also ceased to have significance for him in his relation to Christ. But it is that kind of knowledge which Paul seems to predicate of himself, as having existed in a previous period of his life. He does not use the unreal form of condition; he does not say, "Even if we had known Christ after the flesh (though as a matter of fact we never knew Him so at all), yet now we should know Him so no longer." Apparently, then, when he says "if" he means "although"; he means to say, "Although we have known Christ after the flesh, yet now we know Him so no longer." The knowledge of Christ after the flesh is thus put as an actual fact in Paul's experience, and that can only mean that he knew Him in the way in which His contemporaries knew Him in Galilee and in Jerusalem, a way which in itself, Paul says, was altogether without spiritual significance.
One objection to this interpretation of the passage is that it proves too much. If it means anything, it means that Paul had extended personal acquaintance with Jesus before the crucifixion; for if Paul merely saw Him for a few moments—for example, when the crowds were surging about Him at the time of the last Passover—he could hardly be said to have "known" Him. But, for obvious reasons, any extended intercourse between Paul and Jesus in Palestine is exceedingly improbable. It is natural, therefore, to look for some other interpretation.
Other interpretations undoubtedly are possible. Some of the interpretations that have been proposed must indeed be eliminated. For example, Paul cannot possibly be contrasting a former immature stage of his Christian experience with the present mature stage; he cannot possibly mean, "Even if in the first period after my conversion I had a low view of Christ, which made of Him merely the son of David and the Jewish Messiah, yet now I have come to a higher conception of His divine nature." For the whole point of the passage is found in the sharp break which comes in a man's experience when he appropriates the death and resurrection of Christ. Any consciousness of a subsequent revolution in the thinking of the Christian is not only unsupported anywhere in the Pauline Epistles, but is absolutely excluded by the present passage. Another interpretation also must be eliminated. Paul cannot possibly be contrasting his pre-Christian notions about the Messiah with the higher knowledge which came to him with his conversion; he cannot possibly mean, "Even if before I knew the fulfillment of the Messianic promise I cherished carnal notions of what the Messiah was to be, even if I thought of Him merely as an earthly ruler who was to conquer the enemies of Israel, yet now I have come to have a loftier, more spiritual conception of Him." For the word "Christ," especially without the article, can hardly here be anything other than a proper name, and must refer not to the conception of Messiahship but to the concrete person of Jesus. But another interpretation remains. The key to it is found in the flexible use of the first person plural in the Pauline Epistles. Undoubtedly, the "we" of the whole passage in which 2 Cor. v. 16 is contained refers primarily to Paul himself. But, especially in 2 Cor. v. 16, it may include also all true ambassadors for Christ whose principles are the same as Paul's. Among such true ambassadors there were no doubt to be found some who had known Christ by way of ordinary intercourse in Palestine. "But," says Paul, "even if some of us have known Christ in that way, we know him so no longer." This interpretation is linguistically more satisfactory, perhaps, than that which explains the sentence as simply a more vivid way of presenting a condition contrary to fact. "Granted," Paul would say according to this interpretation, "even that we have known Christ according to the flesh (which as a matter of fact we have not), yet now we know him so no longer." But our interpretation really amounts to almost the same thing so far as Paul is concerned. At any rate, the passage is not so clear as to justify any certain conclusions about Paul's life in Palestine; it does not clearly imply any acquaintance of Paul with Jesus before the passion.
If such acquaintance is to be established, therefore, it must be established on the basis of other evidence. J. Weiss[31] seeks to establish it by the very fact of Paul's conversion. Paul, Weiss believes, saw a vision of the risen Christ. How did he know that the figure which appeared to him in the vision was Jesus? Why did he not think, for example, merely that it was the Messiah, who according to one strain of Jewish Messianic expectation was already existent in heaven? Apparently he recognized the person who appeared to him as Jesus of Nazareth. But how could he have recognized Him as Jesus unless he had seen Jesus before?
This argument depends, of course, altogether upon the naturalistic conception of the conversion of Paul, which regards the experience as an hallucination. In the account of the conversion given in the Book of Acts, on the contrary, it is distinctly said that far from recognizing the person who appeared to him, Paul was obliged to ask the question, "Who art thou, Lord?" and then received the answer, "I am Jesus." Such a conversation between Paul and the One who appeared to him is perfectly possible if there was a real appearance of the risen Christ, but
