blasphemy against the Son of Man, it seems more natural to take the mention of the Son of Man as a secondary interpolation, derived from the same line of tradition, perhaps from the same hand, as the "Son of Man" in the question to the disciples at Caesarea Philippi.
The two other sayings, the one about the Son of Man "who hath not where to lay His head," Matt. viii. 20, and that about the Son of Man who must submit to the reproach of being a glutton and a wine-bibber Matt. xi. 19, belong together. If we assume it to be possible, in conformity with the saying about the purpose of the parables in Mark iv. 11 and 12, that Jesus sometimes spoke words which He did not intend to be understood, we may-if we are unwilling to accept the supposition of a later periphrasis for the ego, which would certainly be the most natural explanation-recognise in these sayings two obscure declarations regarding the Son of Man. They would then be supposed to have meant in the original form, which is no longer clearly recognisable, that the Son of Man would in some way justify the conduct of Jesus of Nazareth. But the way in which this idea is expressed was not such as to make it easy for His hearers to identify Him with the Son of Man. Moreover, it was for them a conception impossible to realise, since Jesus was a natural, and the Son of Man a supernatural, being; and the eschatological scheme of things had not provided for a man who at the end of the existing era should hint to others that at the great transformation of all things He would be manifested as the Son of Man. This case presented itself only in the course of history, and it created a preparatory stage of eschatology which does not answer to any traditional scheme.
That act of the self-consciousness of Jesus by which He recognised Himself in His earthly existence as the future Messiah is the act in which eschatology supremely affirms itself. At the same time, since it brings, spiritually, that which is to come, into the unaltered present, into the existing era, it is the end of eschatology. For it is its "spiritualisation," a spiritualisation of which the ultimate consequence was to be that all its "supersensuous" elements were to be realised only spiritually in the present earthly conditions, and all that is affirmed as supersensuous in the transcendental sense was to be regarded as only the ruined remains of an eschatological world-view. The Messianic secret of Jesus is the basis of Christianity, since it involves the de-nationalising and the spiritualisation of Jewish eschatology.
Yet more. It is the primal fact, the starting-point of a process which manifests itself, indeed, in Christianity, but cannot fully work itself out even here, of a movement in the direction of inwardness which brings all religious magnitudes into the one indivisible spiritual present, and which Christian dogmatic has not
