2 These evils We have openly denounced at every opportunity. In Our communications, We have pointed out to those in authority how closely the interests of religion and the state are intertwined, while at the same time exhorting the faithful to properly cherish and diligently fulfill the teachings of the Church. But Our special appeal has been directed to Our venerable brother bishops, whom the Holy Spirit has set up as leaders in the Church and has imbued with the abundant light of His grace. We urge them to keep watch as sentinels in all parts of the world so that they might know both what remedies are to be applied in the present circumstances and what snares are to be avoided in the case of each individual nation. Thus they should be Our best helpers in Our efforts to obtain the salvation of Catholic nations. And, indeed, We owe abundant thanks to God for the admirable unanimity and concern with which the entire body of bishops has responded to Our exhortation; they use their talents and devotion to defend the Catholic faith and preserve human society. They recall it to the virtues consonant with that faith, away from the greatest ills, thus bringing it to true prosperity.
