"Let it be your first duty to extirpate heretics, but be cautious as to the manner of doing it. Do nothing without consulting the bishop of the diocese in which you may be located, and if there be no bishop there, advise with the metropolitan bishop. He has instructions from Rome, and he understands the character of the people. Be sure not to permit the members of the holy church who may be under your charge to read the Bible. It is the source of all heresy. Wherever you see an opportunity of building a church, make it known to your bishop. Let the land be purchased for the Pope, and his successors in office. Never yield or give up the divine right which the head of the church has, by virtue of the keys, to the command of North America, as well as every other country. The confessional will enable you to know the people by degrees; with the aid of that _holy_ tribunal, and the bishops, who are guided by the spirit of God, we may expect at no distant day, to bring over North America to our holy church."--_Synopsis_, pp.110, 111. The atrocious doctrine that it is proper to equivocate, to dissimulate, and to deceive by mental reservations, is boldly defended by the highest authorities of the Catholic church. Dens says: "Notwithstanding it is not lawful to lie, or to feign what is not, however, it is lawful to dissemble what is, or to cover the truth with words, or other ambiguous or doubtful signs, for a just cause, and when there is not a necessity of confessing."--(Theol., vol. 2, p. 116). Again, he says: "The Vicar of God, in the place of God, remits to man the debt of a plighted promise."--(lb., 4: 134, 135). St. Liqnori says: "It is certain, and a common opinion among all divines, that for a just cause it is lawful to use equivocation, and to confirm it with an oath."--(Less. 1, 2, ch. 41, n. 47).
