In Supremo Apostolatus

In Supremo Apostolatus is a papal bull issued by Pope Gregory XVI regarding the institution of slavery. Issued on December 3, 1839 as a result of a broad consultation among the College of Cardinals, the bull resoundingly denounces both the slave trade and the continuance of the institution of slavery.

The Bull

The Bull outlines the history of Church attitudes to slavery, beginning with the Apostles who tolerated slavery but called on masters to "act well towards their slaves... knowing that the common Master both of themselves and of the slaves is in Heaven, and that with Him there is no distinction of persons". The Bull then discusses the involvement of Christians for and against slavery:

“

In the process of time, the fog of pagan superstition being more completely dissipated and the manners of barbarous people having been softened, thanks to Faith operating by Charity, it at last comes about that, since several centuries, there are no more slaves in the greater number of Christian nations. But - We say with profound sorrow - there were to be found afterwards among the Faithful men who, shamefully blinded by the desire of sordid gain, in lonely and distant countries, did not hesitate to reduce to slavery Indians, negroes and other wretched peoples, or else, by instituting or developing the trade in those who had been made slaves by others, to favour their unworthy practice. Certainly many Roman Pontiffs of glorious memory, Our Predecessors, did not fail, according to the duties of their charge, to blame severely this way of acting as dangerous for the spiritual welfare of those engaged in the traffic and a shame to the Christian name; they foresaw that as a result of this, the infidel peoples would be more and more strengthened in their hatred of the true Religion.

”

The Bull refers to several earlier Papal pronouncements seeking to alleviate the suffering of slaves, beginning with the Letter Apostolic of Paul III, given on May 29, 1537, to the Cardinal Archbishop of Toledo, and that of Urban VIII on April 22, 1639 to the Collector Jurium of the Apostolic Chamber of Portugal; then that of Benedict XIV of December 20, 1741, to the Bishops of Brazil and some other regions; then another by Pius II, of October 7, 1462 and finally Pius VII. Pope Gregory then unambiguously condemns the continuing slave trade:

“

[W]e have judged that it belonged to Our pastoral solicitude to exert Ourselves to turn away the Faithful from the inhuman slave trade in Negroes and all other men. [...] [D]esiring 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 abovementioned 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.

”

Effects in the United States

The Bull was not well received among slave holding Catholics in Maryland which was the center of American Catholic population and governance until the late 19th Century. To avoid penalties from Rome while still supporting the status quo, they often interpreted the bull as denunciation of the slave trade but not as a denunciation of the institution of slavery itself.^{[citation needed]}

Two translations

There are two translations around, which differs in one importand detail. One older is with the word unjustly and one newer without the word. Because of this word some American bishops continued to support slave-holding interests until the abolition of slavery. (→ Catholic Church and slavery)
