Quod Apostolici Muneris §4

⁴ But it is to be lamented that those to whom has been committed the guardianship of the public weal, deceived by the wiles of wicked men and terrified by their threats, have looked upon the Church with a suspicious and even hostile eye, not perceiving that the attempts of the sects would be vain if the doctrine of the Catholic Church and the authority of the Roman Pontiffs had always survived, with the honor that belongs to them, among princes and peoples. For, "the church of the living God, which is the pillar and ground of truth,"(6) hands down those doctrines and precepts whose special object is the safety and peace of society and the uprooting of the evil growth of socialism.
