In regard to religion, mutual toleration in the different professions thereof is what all good and candid minds in all ages have ever practiced, and both by precept and example inculcated on mankind . . . The only sects which he (Locke) thinks ought to be and which by all wise laws are excluded from such toleration are those who teach doctrines subversive of the civil government under which they live. The Roman Catholics or Papists are excluded by reason of such doctrines as these: that princes excommunicated may be deposed, and those they call heretics may be destroyed without mercy; besides their recognizing the pope in so absolute a manner, in subversion of government, by introducing as far as possible into the states under whose protection they enjoy life, liberty, and property that solecism in politics, imperium in imperio, leading directly to the worst anarchy and confusion, civil discord, war and bloodshed.
