What will it cost you, oh Mary, to hear our prayer? What will it cost you to save us? Has not Jesus placed in your hands all the treasures of His grace and mercy? You sit crowned Queen at the right hand of your son: your dominion reaches as far as the heavens and to you are subject the earth and all creatures dwelling thereon. Your dominion reaches even down into the abyss of hell, and you alone, oh Mary, save us from the hands of Satan.
Pope Pius XIs it permitted for Catholics to be present at, or to take part in, conventions, gatherings, meetings, or societies of non-Catholics which aim to associate together under a single agreement everyone who, in any way, lays claim to the name of Christian? In the negative! ... It is clear, therefore, why this Apostolic See has never allowed its subjects to take part in the assemblies of non-Catholics. There is one way in which the unity of Christians may be fostered, and that is by furthering the return to the one true Church of Christ for those who are separated from Her.
Pope Pius XBut since the Modernists (as they are commonly and rightly called) employ a very clever artifice, namely, to present their doctrines without order and systematic arrangement into one whole, scattered and disjointed one from another, so as to appear to be in doubt and uncertainty, while they are in reality firm and steadfast, it will be of advantage, Venerable Brethren, to bring their teachings together here into one group, and to point out the connexion between them, and thus to pass to an examination of the sources of the errors, and to prescribe remedies for averting the evil.
Pope Pius XTruly we are passing through disastrous times, when we may well make our own the lamentation of the Prophet: "There is no truth, and there is no mercy, and there is no knowledge of God in the land" (Hosea 4:1). Yet in the midst of this tide of evil, the Virgin Most Merciful rises before our eyes like a rainbow, as the arbiter of peace between God and man.
