Congregatio de Auxiliis

was a series of formal debates held in Rome between 1598–1607 regarding the nature and extent of divine grace in an effort to resolve a bitter controversy between Dominicans who advocated the Augustinian doctrine of grace as further developed by Thomas Aquinas, and Jesuits, who advocated Molinism. The pope finally declared both viewpoints legitimate and prohibited both sides from calling the other side heretics, and forbade further debate on the subject.
