36 Here We must mention a symptom of this falling away from the Church. It is a very serious matter and fills Our heart - the heart of a Father and universal Pastor of the faithful - with a grief that defies description. For those who profess themselves most interested in the welfare of their country have for some considerable time been striving to disseminate among the people the position, devoid of all truth, that Catholics have the power of directly electing their bishops. To excuse this kind of election they allege a need to look after the good souls with all possible speed and to entrust the administration of dioceses to those pastors who, because they do not oppose the communist desires and political methods, are acceptable by the civil power.
