Libertas §39

³⁹ But this teaching is understood in two ways. Many wish the State to be separated from the Church wholly and entirely, so that with regard to every right of human society, in institutions, customs, and laws, the offices of State, and the education of youth, they would pay no more regard to the Church than if she did not exist; and, at most, would allow the citizens individually to attend to their religion in private if so minded. Against such as these, all the arguments by which We disprove the principle of separation of Church and State are conclusive; with this super-added, that it is absurd the citizen should respect the Church, while the State may hold her in contempt.
