Pastorale officium

Pastorale officium was an Apostolic Brief issued by Pope Paul III, May 29, 1537, to Cardinal Juan Pardo de Tavera which declares that anyone who enslaved or despoiled indigenous Americans would be automatically excommunicated.
The harsh threat of punishment (Latae sententiae) contained in Pastorale officium made the Conquistadors complain to the Spanish king and Emperor. Charles V went on to argue that the letter was injurious to the Imperial right of colonization and harmful to the peace of the Indies. The urging of Charles V to revoke the briefs and bulls of 1537 and exemplifies the tension of the concern for evangelisation as manifested in the teachings of 1537 and the pressure to honor the system of royal patronage. The weakened position of the pope and the memory of the Sack of Rome (1527) a decade earlier by imperial troops, made the ecclesiastical authorities hesitant in engaging in any possible confrontation with the Emperor. Under mounting pressure Pope Paul III succumbed and removed the ecclesiastical censures in the letter titled ""Non Indecens Videtur" ".
The annulling of the ecclesiastical letter was not a denial of the doctrinal teaching of the spiritual equivalence of all human beings. The annulation gave rise to the subsequent
papal encyclical Sublimis Deus promulgated by Pope Paul III on June 2, 1537 Thus the "Pastorale officium" has been seen as a companion document for the encyclical "Sublimis Deus".
Stogre (1992) notes that "Sublimus Dei" is not present in Denzinger compendium of theological-historical source texts.
