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.
