When Authority has had a long dominion, and its abuse too has been long, a reaction occurs: Liberty has her revenge; but in her turn is prone to compromise her interests by abuses and by excess. It is the history of all human society; facts prove it quite as much as common sense foretells it. In the bosom of this general fact it is the peculiar character, as it is the glory, of Christianity that it has fully accepted these two rival forces; and the one in the face of the other--authority and liberty--both of divine origin. {33} Christianity has constantly accounted them for such as they are--the one the revealed law of God, the other the innate right of man, whom God created free and responsible. The history of the Jews is only that of the intimate and continued relations between God as sovereign and man as free agent; God uttering and giving the law, man using his liberty at one time to fulfill, at another to reject, the law of God. When the great day of humanity dawned and Jesus came, it was in liberty's name, and in claiming the right of the soul to obey the divine law according to its convictions, that Christianity engaged in its primitive struggle of three centuries. Under this banner, too, it conquered, and under it religious society and civil society combined without becoming identical. The tempestuous and painful fecundity of the middle ages succeeded to the tyrannical unity of the Roman empire, so sterile in result. {34} Hence principles the most inconsistent, issues the most contradictory--the power of religion and the power of the state--popes and kings now supporting, now combating each other's ambitious purposes, and thwarting each other's measures, without any regard to law or right; liberty sometimes suffering cruelly by their alliance, sometimes happily profiting by their dissensions; on some occasions popes, on others monarchs protecting liberty against their reciprocal pretensions and excesses. Spiritual and temporal princes still wavered in their maxims and in their policy, and did not during the middle ages systematically and on all occasions form coalitions, of which liberty was to pay the cost. Liberty, on the contrary, continued to subsist and to grow in the midst of their rivalries and of her own sufferings. But these rivalries and these sufferings produced a chaos which recurred incessantly, and became ever more and more intolerable, precisely on account of the progress still made, and which no effort could stifle. {35} The great body of Christians at last demanded some issue from this chaos; then those who wielded the religious power and the civil power, now separately, now in concert, endeavored to satisfy the craving of the world; and by their councils, pragmatic sanctions, encyclical letters and concordats, sought to reform the abuses and the grievances which, as men loudly proclaimed, existed, if not in the Church itself, at least in the relations of the Church with the State.
