23 That several years ago different important acts of legislation in France proceeded from a tendency hostile to religion, and therefore to the interests of the nation, is admitted by all, and unfortunately confirmed by the evidence of facts. We Ourselves, in obedience to a sacred duty, made earnest appeals to him who was then at the head of the republic, but these tendencies continued to exist; the evil grew, and it was not surprising that the members of the French Episcopate chosen by the Holy Ghost to rule over their respective illustrious churches should even quite recently have considered it an obligation publicly to express their grief concerning the condition of affairs in France in regard to the Catholic religion. Poor France! God alone can measure the abyss of evil into which she will sink if this legislation, instead of improving, will stubbornly continue in a course which must end in plucking from the minds and hearts of Frenchmen the religion which has made them so great.
