Wherever Protestantism prevailed, intolerance became a principle of State, and was proclaimed in theory even where the Protestants were in a minority, and where the theory supplied a weapon against themselves. The Reformation made it a general law, not only against Catholics by way of self-defence or retaliation, but against all who dissented from the reformed doctrines, whom it treated, not as enemies, but as criminals,--against the Protestant sects, against Socinians, and against atheists. It was not a right, but a duty; its object was to avenge God, not to preserve order. There is no analogy between the persecution which preserves and the persecution which attacks; or between intolerance as a religious duty, and intolerance as a necessity of State. The Reformers unanimously declared persecution to be incumbent on the civil power; and the Protestant Governments universally acted upon their injunctions, until scepticism escaped the infliction of penal laws and condemned their spirit. Doubtless, in the interest of their religion, they acted wisely. Freedom is not more decidedly the natural condition of Catholicism than intolerance is of Protestantism; which by the help of persecution succeeded in establishing itself in countries where it had no root in the affections of the people, and in preserving itself from the internal divisions which follow free inquiry. Toleration has been at once a cause and an effect of its decline. The Catholic Church, on the other hand, supported the mediaeval State by religious unity, and has saved herself in the modern State by religious freedom. No longer compelled to devise theories in justification of a system imposed on her by the exigencies of half-organised societies, she is enabled to revert to a policy more suited to her nature and to her most venerable traditions; and the principle of liberty has already restored to her much of that which the principle of unity took away. It was not, as our author imagines (p. 119), by the protection of Lewis XIV. that she was formidable; nor is it true that in consequence of the loss of temporalities, "the chill of death is gathering round the heart of the great theocracy" (p. 94); nor that "the visible decline of the papacy" is at hand because it no longer wields "the more efficacious arms of the great Catholic monarchies" (p. 190). The same appeal to force, the same principles of intolerance which expelled Catholicism from Protestant countries, gave rise in Catholic countries to the growth of infidelity. The Revolutions of 1789 in France, and of 1859 in Italy, attest the danger of a practice which requires for its support the doctrines of another religion, or the circumstances of a different age. Not till the Church had lost those props in which Mr. Goldwin Smith sees the secret of her power, did she recover her elasticity and her expansive vigour. Catholics may have learnt this truth late, but Protestants, it appears, have yet to learn it.
