I’m familiar with Immensa Pastorum, and I agree with you it’s a rebuking of slavery – albeit only natives of the Americas. It would be more appropriate if I’d said “The first time the Church really made a strong statement against slavery
as a whole was In Supremo Apostolatus in the 19th century.” I do have to do some reading and research on some of the other bulls you’ve presented, so thank you for that.
One bull you mentioned that I am already acutely aware of is Sicut Dudum. I’ve said it before and I’ll say it again: Using Sicut Dudum to defend the Church’s position on slavery would be like using Upton Sinclair’s
The Jungle to defend the meatpacking industry. Before that was Creator Omnium, which made it clear that there was a penalty for enslaving Christians. Imagine a state passed a law making it illegal to assault women of only certain nationality or race instead of all women. Surely that makes clear those women not listed in the law are given no such protection.
The key to Sicut Dudum is in the second section:
- Some of these people were already baptized; others were even at times tricked and deceived by the promise of Baptism, having been made a promise of safety that was not kept. They have deprived the natives of the property, or turned it to their own use, and have subjected some of the inhabitants of said islands to perpetual slavery, sold them to other persons, and committed other various illicit and evil deeds against them, because of which very many of those remaining on said islands, and condemning such slavery, have remained involved in their former errors, having drawn back their intention to receive Baptism, thus offending the majesty of God, putting their souls in danger, and causing no little harm to the Christian religion
We see that the pope is unhappy, not because of the people in general being enslaved, but that A. People were enslaved after either being baptized or after promising to become baptized, B. That the baptisms came with a promise of safety that was not kept, C. Some natives of the Canary Islands have withdrawn their intention to be baptized or practicing their earlier faith because there was no point in becoming baptized if it offered no protection, D. That this was causing harm to Christianity.
It’s an interesting phrase, a “promise of safety”. It’s not unlike “protection” offered by neighborhood toughs to avoid being roughed up by those same toughs.
If that wasn’t clear enough, after complaints by King Duarte of Portugal, it was amended to make quite clear that the Portuguese were to have free reign acquiring slaves so long as they didn’t take Christians.
There have been those within the Church who have spoken out against slavery, but as a whole the voice of the Church can best be described as mixed. Also, your examples only go back to the 15th century – ignoring those documents like Dum Diversas which specifically allows for the enslavement of all non-Christians with no limit to time or space. If we go back further we see more documents like the Fourth Council of Toledo and the Ecumenical Council of Chalcedon which also sees no problem in enslaving non-Christians.
