THE title, "Son of Man," occurs some sixty-eight times in the Synoptic Gospels, invariably on the lips of Jesus. It is precisely this fact which constitutes the baffling interpretive problems with respect to the "Son of Man" and which makes this title, or the use of it, so important for understanding Jesus' self-consciousness. For no other character in the Synoptic narratives refers to the Son of Man, nor do the several Gospel writers themselves, nor for that matter do the authors of the Epistles. It is a term used exclusively-according to the tradition-by Jesus, who, moreover, employs no other title to characterize the messianic redeemer of God, to whom he is somehow mysteriously related. As John Knox puts it, in The Death of Christ:' "This striking fact creates a very strong presumption that Jesus was actually remembered to have used the phrase and that he used it with some seriousness and impressiveness. The early Church can hardly be thought of as originating the phrase and then confining it so narrowly to Jesus' own usage." This puts the dilemma about as sharply as possible, and, of the scholars investigated for this study, only Hans Lietzmann argues that none of the Son of Man sayings are authentic. All others have attempted to show that at least some of the sayings are authentic, which accounts for the fact that Jesus was actually remembered to have used the phrase. It can also be used as a device to explain why the community was led to attribute further usage of the term to Jesus in contexts of which the authenticity may now be questioned. Invariably, the argument for unauthenticity of one group of sayings rests upon a prior judgment that another group, or groups, are authentic. On the other hand, no modern critical scholar claims that all the sayings are authentic. It is already apparent that the Son of Man sayings can be grouped fairly unambiguously into three categories, which must become the basis for any analytical investigation.2 Among scholars, there are discrepancies in detail, but on the whole this schema is accepted in one form or another. We have said that the title occurs sixty-eight times in the Synoptics. When parallels are eliminated, the number of different occurrences is reduced to forty. Of this number, the Son of Man is referred to in the general context of apocalypticism nineteen times, according to Knox,3 and sixteen times, according to Eduard Schweizer.4 Following the suggestion of Knox, we shall call this Group A; here the exaltation of the Son of Man at God's right hand is being affirmed, or his coming on the clouds of heaven is being predicted. A second category, Group B, has to do with the suffering which Jesus has to undergo, specifical* Peter C. Hodgson has an A.B. degree from Princeton and B.D. and M.A. degrees from Yale.
