Pope Gregory XVI issues the encyclical In Supremo Apostolatus stating, “…the slave trade, although it has diminished in more than one district, is still practiced by numerous Christians.

This is why, desiring to remove such a shame from all the Christian nations, having fully reflected over the whole question and having taken the advice of many of Our Venerable Brothers the Cardinals of the Holy Roman Church, and walking in the footsteps of Our Predecessors, We warn and adjure earnestly in the Lord faithful Christians of every condition that no one in the future dare to vex anyone, despoil him of his possessions, reduce to servitude, or lend aid and favor to those who give themselves up to these practices, or exercise that inhuman traffic by which the Blacks, as if they were not men but rather animals, having been brought into servitude, in no matter what way, are, without any distinction, in contempt of the rights of justice and humanity, bought, sold, and devoted sometimes to the hardest labor… We reprove, then, by virtue of Our Apostolic Authority, all the practices above-mentioned as absolutely unworthy of the Christian name.

By the same Authority We prohibit and strictly forbid any Ecclesiastic or lay person from presuming to defend as permissible this traffic in Blacks under no matter what pretext or excuse, or from publishing or teaching in any manner whatsoever, in public or privately, opinions contrary to what We have set forth in this Apostolic Letter.” (December 3, 1839)
