You didn’t really answer the objection to Dum diversa
What is the objection that must be answered?
As I stated already, the context appears to be about authorizing a crusade, of which servitude of the enemies of Christendom was clearly a part. The Saracens and pagans who for centuries were attacking the Iberian Peninsula did the same, as this was the common practice of warfare throughout the crusades. What doctrinal significance does this have?
We’ve already established that according to Catholic doctrine, just war, just capital punishment, and just slavery was and still is Catholic doctrine. Yet, there are unjust forms of slavery, ie. chattel slavery, which was condemned by popes in the 1400s, 1500s, 1600s, 1700s, 1800s and at Vatican II. The
doctrine has not changed.
According Catholic author Mark Brumley, in his article entitled
Let My People Go (This Rock: July/August 1999),
"there are circumstances in which a person can justly be compelled to servitude against his will. Prisoners of war or criminals, for example, can justly lose their circumstantial freedom and be forced into servitude, within certain limits."
The bull you cite connotes this kind of just servitude. It may very well have been unjustly executed, as “just wars” can be unjustly executed. But that has little affect on the doctrine of just war, nor on the doctrine of just servitude. The pope by no means authorized the King of portugal to enslave Christians who resided in the lands he conquered, which would have been unjust chattel slavery.
Furthermore, the point which appears to be escaping michaelmac’s and your grasp is concisely explained by the
Protestant article I linked to above by Rodney Stark (2003)

The Truth About the Catholic Church and Slavery
The problem wasn’t that the leadership was silent. It was that almost nobody listened.

It is true that some popes did not observe the moral obligation to oppose slavery—indeed, in 1488 Pope Innocent VIII accepted a gift of a hundred Moorish slaves from King Ferdinand of Aragon, giving some of them to his favorite cardinals. Of course, Innocent was anything but that when it came to a whole list of immoral actions. However, laxity must not be confused with doctrine. Thus while Innocent fathered many children, he did not retract the official doctrine that the clergy should be celibate. In similar fashion, his acceptance of a gift of slaves should not be confused with official Church teachings. These were enunciated often and explicitly as they became pertinent.
Your thesis seems to imply that sins of popes or priests equates to the doctrine of Church. By that logic, fornication must have been approved doctrine of the Catholic Church, as popes have also fornicated. Idolatry must have been Jewish doctrine, as much of Judaism committed such sins in the OT, right? Yet, such logic is absurd. It lacks even an introductory understanding dogmatic theology.
Doctrine on slavery is not derived from bulls authorizing a specific king to conquer the enemies of Christendom. Such bulls are not primarily and exercise of the pope’s teaching authority, but are an exercise of his governing authority. The bull you cite is about authorizing a crusade and the servitude of those who are deemed enemies of Christendom. This merely reinforces that there exists a difference bewteen just servitude and chattel slavery.
The US Constitution recognized this difference, and so does the Catholic Church. Enemies of the state and criminals can and have been given forced labor in accord with international laws. You may not like this practice either, but you will have to take that up with the federal government and international treaties.
As for the topic of this thread, it is about what the Church teaches about the morality of slavery. As stated by many sources already cited, before and after Vatican II, there are just forms of slavery and unjust forms according to Catholic doctrine, just as there are for just war and just capital punishment. All of these are ripe for abuse in practice, and so
in practice the Church is opposed to war, capital punishment and slavery, although Catholic doctrine continues to affirm that these things are not inherently evil.
