All this is just and acute criticism. The charge to the Twelve is not a discourse of instruction. What Jesus there sets before the disciples they could not at that time have understood, and the promises which He makes to them are not appropriate to their circumstances. Many of the discourses are mere bundles of heterogeneous sayings, though this is not so much the case in Mark as in the others. He has not forgotten that effective polemic consists of short, pointed, incisive arguments. The others, as advanced theologians, are of opinion that it is fitting to indulge in arguments which have nothing to do with the matter in hand, or only the most distant connexion with it. They form the transition to the discourses of the Fourth Gospel, which usually degenerate into an aimless wrangle. In the same connexion it is rightly observed that the discourses of Jesus do not advance from point to point by the logical development of an idea, the thoughts are merely strung together one after another, the only connexion, if connexion there is, being due to a kind of conventional mould in which the discourse is cast. The parables, Bauer continues, present difficulties no less great. It is an ineptitude on the part of the apologists to suggest that the parables are intended to make things clear. Jesus Himself contradicts this view by saying bluntly and unambiguously to His disciples that to them it was given to know the mysteries of the Kingdom of God, but to the people all His teaching must be spoken as parables, that “seeing they might see and not perceive, and hearing they might hear and not understand.” The parables were therefore intended only to exercise the intelligence of the disciples; and so far from being understood by the people, mystified and repelled them; as if it would not have been much better to exercise the minds of the disciples in this way when He was alone with them. The disciples, however, do not even understand the simple parable of the Sower, but need to have it interpreted to them, so that the Evangelist once more stultifies his own theory. Bruno Bauer is right in his observation that the parables offer a serious problem, seeing that they were intended to conceal and not to make plain, and that Jesus nevertheless taught only in parables. The character of the difficulty, however, is such that even literary criticism has no explanation ready. Bruno Bauer admits that he does not know what was in the mind of the Evangelist when he composed these parables, and thinks that he had no very definite purpose, or at least that the suggestions which were floating in his mind were not worked up into a clearly ordered whole.
