On the other hand, the theistic content of Jesus' teaching is immeasurably strengthened when enforced by His divine authority, and read in the light of His Incarnation, Passion and Resurrection. As Drews remarks: "The chief obstacle to a monistic religion and attitude is the belief irreconcilable with reason or history, in the historical reality of a 'unique,' ideal, and unsurpassable redeemer."[46] Certainly the assurance that God is a loving Father and that we are His children, said to be the essence of Christianity, is wonderfully safeguarded and buttressed by the doctrines, or facts, of an Incarnate, Crucified, and Risen Christ. 46: "The Christ-Myth," p. 300. Whatever happens to the Christian doctrines and the Christian history, many will declare that the ethical teaching of Jesus will remain, and will continue to exercise its empire over the lives of men. But such an inference finds little support in present conditions. An aggressive militarism maintains that each nation should be free to develop its own religious ideas, and chides Strauss with half-way measures in holding to Christian ethics while discarding Christian doctrines and miracles. A militant feminism which objects to the marriage service, and a militant socialism which sees in the family the main support of the right of private property, will not, if they have their way, leave the marriage relation unaffected. Jesus taught, we are reminded, in a pre-scientific and a pre-Darwinian age. His teaching, in fact, whatever its acknowledged excellence and importance, was but a phase, and that not the final phase, of moral evolution. His teaching, as many hold, was only an _Interimsethik_, not intended to be the norm for all men and all time. There is no assurance that even the character of Christ will remain undimmed in splendour, and undiminished in power of appeal, for there is no evidence for sinlessness, except evidence which is rejected on the ground of exaggeration or idealization in the case of miracles, and other claims implying the supernatural. Christian ethics doubtless makes an appeal of its own, but apart from the support of Christology its supremacy is by no means assured. If we go back to the moral teaching or to the example of Jesus alone, there will be no teaching with authority, no divine Teacher who is the Truth, and no regenerative power of the Spirit behind the teaching. The power of Christ's example lies in the union of humility and authority. "Take Christ's difference from us out of Christianity and His identity with us loses all its glorious power." If their Lord and Master washes the disciples' feet, the example comes with the force of a divine command: "Ye ought also to wash one another's feet." It is not merely a beautiful act to be admired (or perhaps by some to be despised); it is a divine imperative to be obeyed.
