|IN SUPREMO APOSTOLATUS|
|Pope Gregory XVI - 1839|
In our time Pius VII, moved by the same religious and charitable spirit as his Predecessors, intervened zealously with those in possession of power to secure that the slave trade should at least cease amongst the Christians. The penalties imposed and the care given by Our Predecessors contributed in no small measure, with the help of God, to protect the Indians and the other people mentioned against the cruelty of the invaders or the cupidity of Christian merchants, without however carrying success to such a point that the Holy See could rejoice over the complete success of its efforts in this direction; for 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 favour 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 labour. Further, in the hope of gain, propositions of purchase being made to the first owners of the Blacks, dissensions and almost perpetual conflicts are aroused in these regions.
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.
