28 Would that all men would judge of the tree by its fruit, and would acknowledge the seed and origin of the evils which press upon us, and of the dangers that are impending! We have to deal with a deceitful and crafty enemy, who, gratifying the ears of people and of princes, has ensnared them by smooth speeches and by adulation. Ingratiating themselves with rulers under a pretense of friendship, the Freemasons have endeavoured to make them their allies and powerful helpers for the destruction of the Christian name; and that they might more strongly urge them on, they have, with determined calumny, accused the Church of invidiously contending with rulers in matters that affect their authority and sovereign power. Having, by these artifices, insured their own safety and audacity, they have begun to exercise great weight in the government of States; but nevertheless they are prepared to shake the foundations of empires, to harass the rulers of the State, to accuse, and to cast them out, as often as they appear to govern otherwise than they themselves could have wished. In like manner, they have by flattery deluded the people. Proclaiming with a loud voice liberty and public prosperity, and saying that it was owing to the Church and to sovereigns that the multitude were not drawn out of their unjust servitude and poverty, they have imposed upon the people, and, exciting them by a thirst for novelty, they have urged them to assail both the Church and the civil power. Nevertheless, the expectation of the benefits which was hoped for is greater than the reality; indeed, the common people, more oppressed than they were before, are deprived in their misery of that solace which, if things had been arranged in a Christian manner, they would have had with ease and in abundance. But, whoever strive against the order which Divine Providence has constituted pay usually the penalty of their pride, and meet with affliction and misery where they rashly hoped to find all things prosperous and in conformity with their desires.
