But, if so, then we can commit ourselves to these dogmas in the same way, and degree, as we commit ourselves to Him. We can do so, in the absolute assurance that He cannot but abide for ever, that which we know Him to be to-day. We know Him indeed, but 'in part:' but it is part of a fixed and integral character, which is whole in every part; and can never falsify, in the future, the revelation which it has already made of itself. The real question, as to Christian dogma, lies in the prior question--Is Christianity justified in claiming to have reached a _final_ position? If the position is rightly final, then the intellectual expression of its inherent elements is final also. Here is the deep contrast between it and science. The scientific man is forbidden, by the very nature of his studies, to assume finality for his propositions. For he is not yet in command of his material. Far, very far, from it. He is touching it on its very edge. He is engaged in slowly pushing tentative advances into an unknown world, looming, vast, dim, manifold, beyond his frontier of light. The coherence of his known matter with that huge mass beyond his ken, can be but faintly imaged and suspected. Wholly unreckoned forces are in operation. At any moment he may be called upon to throw over the classification which sums up his hitherto experience; he may have to adopt a new centre; to bring his facts into a novel focus; and this involves at once a novel principle of arrangement. In such conditions dogma is, of course, an absurdity. But, if we are in a position to have any faith in Jesus Christ, then we must suppose that we have arrived at the one centre to all possible experiences, the one focus, under which all sights must fall. To believe in Him at all is to believe that, by and in 'this Man, will God judge the world.' In His personality, in His character, we are in possession of the ultimate principle, under which the final estimate of all things will be taken. We have given us, in His sacrifice and mission, the absolute rule, standard, test, right to the very end. Nothing can fall outside it. In Him, God has summed up creation. We have touched, in Him, the 'last days,' the ultimate stage of all development. We cannot believe in Him at all, and not believe that His message is final. And it is this finality which justifies dogma. If Christianity is final, it can afford to be dogmatic; and we, who give our adhesion to it, must, in so doing, profess our adhesion to the irreversible nature of its inherent principles: for, in so doing, we are but re-asserting our belief in the absolute and final sufficiency of His person.
