Indians, negroes, or other classes of men, or be accessories to others, or furnish them aid or assistance in so doing; and on no account henceforth to exercise that inhuman traffic by which negroes are reduced to slavery, as if they were not men, but automata or chattels, and are sold in defiance of all the laws of justice and humanity, and devoted to severe and intolerable labors. We further reprobate, by our apostolical authority, all the above-described offences as utterly unworthy of the Christian name; and by the same authority we rigidly prohibit and interdict all and every individual, whether ecclesiastical or laical, from presuming to defend that commerce in negro slaves under pretence or borrowed color, or to teach or publish in any manner, publicly or privately, things contrary to the admonitions which we have given in these letters. "And, finally, that these, our letters, may be rendered more apparent to all, and that no person may allege any ignorance thereof, we decree and order that it shall be published according to custom, and copies thereof be properly affixed to the gates of St. Peter and of the Apostolic Chancel, every and in like manner to the General Court of Mount Citatorio, and in the field of the Campus Florae and also through the city, by one of our heralds, according to aforesaid custom. "Given at Rome, at the Palace of Santa Maria Major, under the seal of the fisherman, on the 3d day of December, 1837, and in the ninth year of our pontificate. "Countersigned by Cardinal A. Lambruschini." We have already quoted the language of Pope Leo X., who says:-- "Not only does the Christian religion, but nature herself cry out against the State of slavery." The Abbe Raynal says:-- "He who supports slavery is the enemy of the human race. He divides it into two societies of legal assassins, the oppressors and the oppressed. I shall not be afraid to cite to the tribunal of reason and justice those governments which tolerate this cruelty, or which even are not ashamed to make it the basis of their power." From the proceedings of a Massachusetts Anti-slavery Convention in 1855, we make the following extract:-- "Henry Kemp, a Roman Catholic, came forward to defend the Romish Church in reply to Mr. Foster. He claimed that the Catholic Church is thoroughly anti-slavery--as thoroughly as even his friend Foster."
