Although the doctrine of self-reliance and self-denial, which is the foundation of political economy, was written as legibly in the New Testament as in the _Wealth of Nations_, it was not recognised until our age. Tertullian boasts of the passive obedience of the Christians. Melito writes to a pagan Emperor as if he were incapable of giving an unjust command; and in Christian times Optatus thought that whoever presumed to find fault with his sovereign exalted himself almost to the level of a god. But this political quietism was not universal. Origen, the ablest writer of early times, spoke with approval of conspiring for the destruction of tyranny. After the fourth century the declarations against slavery are earnest and continual. And in a theological but yet pregnant sense, divines of the second century insist on liberty, and divines of the fourth century on equality. There was one essential and inevitable transformation in politics. Popular governments had existed, and also mixed and federal governments, but there had been no limited government, no State the circumference of whose authority had been defined by a force external to its own. That was the great problem which philosophy had raised, and which no statesmanship had been able to solve. Those who proclaimed the assistance of a higher authority had indeed drawn a metaphysical barrier before the governments, but they had not known how to make it real. All that Socrates could effect by way of protest against the tyranny of the reformed democracy was to die for his convictions. The Stoics could only advise the wise man to hold aloof from politics, keeping the unwritten law in his heart. But when Christ said: "Render unto Caesar the things that are Caesar's, and unto God the things that are God's," those words, spoken on His last visit to the Temple, three days before His death, gave to the civil power, under the protection of conscience, a sacredness it had never enjoyed, and bounds it had never acknowledged; and they were the repudiation of absolutism and the inauguration of freedom. For our Lord not only delivered the precept, but created the force to execute it. To maintain the necessary immunity in one supreme sphere, to reduce all political authority within defined limits, ceased to be an aspiration of patient reasoners, and was made the perpetual charge and care of the most energetic institution and the most universal association in the world. The new law, the new spirit, the new authority, gave to liberty a meaning and a value it had not possessed in the philosophy or in the constitution of Greece or Rome before the knowledge of the truth that makes us free.
