Bellarmine himself was not a stranger to theological condemnation. In August 1590 Pope Sixtus V decided to place the first volume of the Controversies on the Index because Bellarmine had argued that the pope is not the temporal ruler of the whole world and that temporal rulers do not derive their authority to rule from God through the pope but through the consent of the people governed. However Sixtus died before the revised Index was published, and the next pope, Urban VII, who reigned for only twelve days before his own death, removed Bellarmine's book from the list during that brief period. The times were precarious.
