A further cause which has operated to prevent theology from obtaining the benefit of free discussion is the interpretation popularly placed upon the constitution of the Church Establishment. For fifteen centuries of its existence, the Christian Church was supposed to be under the immediate guidance of the Holy Spirit, which miraculously controlled its decisions, and precluded the possibility of error. This theory broke down at the Reformation, but it left behind it a confused sense that theological truth was in some way different from other truth; and, partly on grounds of public policy, partly because it was supposed to have succeeded to the obligations and the rights of the Papacy, the State took upon itself to fix by statute the doctrines which should be taught to the people. The distractions created by divided opinions were then dangerous. Individuals did not hesitate to ascribe to themselves the infallibility which they denied to the Church. Everybody was intolerant upon principle, and was ready to cut the throat of an opponent whom his arguments had failed to convince. The State, while it made no pretensions to Divine guidance, was compelled to interfere in self-protection; and to keep the peace of the realm, and to prevent the nation from tearing itself in pieces, a body of formulas was enacted, for the time broad and comprehensive, within which opinion might be allowed convenient latitude, while forbidden to pass beyond the border. It might have been thought that in abandoning for itself, and formally denying to the Church its pretensions to immunity from error, the State could not have intended to bind the conscience. When this or that law is passed, the subject is required to obey it, but he is not required to approve of the law as just. The Prayer-Book and the Thirty-nine Articles, so far as they are made obligatory by Act of Parliament, are as much laws as any other statute. They are a rule to conduct; it is not easy to see why they should be more; it is not easy to see why they should have been supposed to deprive clergymen of a right to their opinions, or to forbid discussion of their contents. The judge is not forbidden to ameliorate the law which he administers. If in discharge of his duty he has to pronounce a sentence which he declares at the same time that he thinks unjust, no indignant public accuses him of dishonesty, or requires him to resign his office. The soldier is asked no questions as to the legitimacy of the war on which he is sent to fight; nor need he throw up his commission if he think the quarrel a bad one. Doubtless, if a law was utterly iniquitous--if a war was unmistakably wicked--honourable men might feel uncertain what to do, and would seek some other profession rather than continue instruments of evil. But within limits, and in questions of detail, where the service is generally good and honourable, we leave opinion its free play, and exaggerated scrupulousness would be folly or something worse.
