The constitution and the spirit of the masonic sect were clearly discovered by manifest signs of its actions, by the investigation of its causes, by … - Leo XIII

Whoever has received from the divine bounty a large share of temporal blessings, whether they be external and material, or gifts of the mind, has received them for the purpose of using them for the perfecting of his own nature, and, at the same time, that he may employ them, as the steward of God's providence, for the benefit of others.

You have truly spoken, Cardinal : since We have been Pope, Our regards have turned towards that disinherited land. Our heart has been touched at the thought of the enormous amount of physical and moral misery that exists there. We have repeatedly urged all those who have power in their hands to put a stop to the hideous traffic called the slave-trade, and to use all and every means to secure that end. And, in as much as the African Continent is the principal scene of this traffic and, as it were, the home of slavery, We recommend all missionaries who there preach the Holy Gospel to devote their whole efforts, their whole life, to this sublime work of redemption. But it is upon you, Cardinal, that We count especially for success.

There are several organized bodies which, though differing in name, in ceremonial, in form and origin, are nevertheless so bound together by community of purpose and by the similarity of their main opinions, as to make in fact one thing with the sect of the Freemasons, which is a kind of center whence they all go forth, and whither they all return. Now, these no longer show a desire to remain concealed; for they hold their meetings in the daylight and before the public eye, and publish their own newspaper organs; and yet, when thoroughly understood, they are found still to retain the nature and the habits of secret societies. (...) With a fraudulent external appearance, and with a style of simulation which is always the same, the Freemasons, like the Manichees of old, strive, as far as possible, to conceal themselves, and to admit no witnesses but their own members. As a convenient manner of concealment, they assume the character of literary men and scholars associated for purposes of learning. They speak of their zeal for a more cultured refinement, and of their love for the poor; and they declare their one wish to be the amelioration of the condition of the masses, and to share with the largest possible number all the benefits of civil life. Were these purposes aimed at in real truth, they are by no means the whole of their object.
