9 Accordingly, under the admonition of the duty of Our Apostolic office that, in the face of such audacity on the part of the enemies of God, We should most vigilantly protect the dignity and honor of religion and preserve the sacred rights of the Catholic Church, We by our Apostolic authority denounce, condemn, and reject the Law for the Separation of Church and State in the Portuguese Republic. This law despises God and repudiates the Catholic faith; it annuls the treaties solemnly made between Portugal and the Apostolic See, and violates the law of nature and of her property; it oppresses the liberty of the Church, and assails her divine Constitution; it injures and insults the majesty of the Roman Pontificate, the order of Bishops, the Portuguese clergy and people, and so the Catholics of the world. And whilst We strenuously complain that such a law should have been made, sanctioned, and published, We utter a solemn protest against those who have had a part in it as authors or helpers, and, at the same time, We proclaim and denounce as null and void, and to be so regarded, all that the law has enacted against the inviolable rights of the Church.
