14 Nor do they think it enough to disregard the Church - the best of guides - unless they also injure it by their hostility. Indeed, with them it is lawful to attack with impunity the very foundations of the Catholic religion, in speech, in writing, and in teaching; and even the rights of the Church are not spared, and the offices with which it is divinely invested are not safe. The least possible liberty to manage affairs is left to the Church; and this is done by laws not apparently very hostile, but in reality framed and fitted to hinder freedom of action. Moreover, We see exceptional and onerous laws imposed upon the clergy, to the end that they may be continually diminished in number and in necessary means. We see also the remnants of the possessions of the Church fettered by the strictest conditions, and subjected to the power and arbitrary will of the administrators of the State, and the religious orders rooted up and scattered.
