And, against the doctrine of Scripture, of the Church, and of the Holy Fathers, they do not hesitate to assert that "that is the best condition of civil society, in which no duty is recognized, as attached to the civil power, of restraining by enacted penalties, offenders against the Catholic religion, except so far as public peace may require." From which totally false idea of social government they do not fear to foster that erroneous opinion, most fatal in its effects on the Catholic Church and the salvation of souls, called by Our Predecessor, Gregory XVI, an "insanity,"2 viz., that "liberty of conscience and worship is each man's personal right, which ought to be legally proclaimed and asserted in every rightly constituted society; and that a right resides in the citizens to an absolute liberty, which should be restrained by no authority whether ecclesiastical or civil, whereby they may be able openly and publicly to manifest and declare any of their ideas whatever, either by word of mouth, by the press, or in any other way."

The state must, therefore, be separated from the Church, and the Catholic from the citizen. Every Catholic, from the fact that he is also a citizen, has the right and the duty to work for the common good in the way he thinks best, without troubling himself about the authority of the Church, without paying any heed to its wishes, its counsels, its orders--nay, even in spite of its rebukes. For the Church to trace out and prescribe for the citizen any line of action, on any pretext whatsoever, is to be guilty of an abuse of authority, against which one is bound to protest with all one's might. Venerable Brethren, the principles from which these doctrines spring have been solemnly condemned by Our predecessor, Pius VI, in his Apostolic Constitution Auctorem fidei.
