37 If, then, you desire, as you certainly do, beloved sons, that in the formidable contest being waged against the Church by anti-Christian sects and by the city of the evil one, the victory be for God and His Church, it is absolutely necessary for you to fight all together in perfect order and discipline under the command of your hierarchical leaders. Pay no heed to those pernicious men who, though calling themselves Christians and Catholics, throw tares into the field of the Lord and sow division in His Church by attacking and often even calumniating the Bishops "established by the Holy Ghost to rule the Church of God."(27) Read neither their pamphlets nor their papers. No good priest should in any way lend authority either to their ideas or to their license of speech. Can he ever forget that on the day of his ordination he promised "obedientiam et reverentiam" to his Bishop before the holy altar?
