Arise, O Lord, and judge your own cause. Remember your reproaches to those who are filled with foolishness all through the day. Listen to our prayers, for foxes have arisen seeking to destroy the vineyard whose winepress you alone have trod.
Pope Leo XThis devotion, so great and so confident, to the august Queen of Heaven, has never forth with such brilliancy as when the militant Church of Go has seemed to be endangered by the violence of heresy spread abroad, or by an intolerable moral corruption, or by the attacks of powerful enemies. Ancient and modern history and the more sacred annals of the Church bears witness to public and private supplications addressed to the Mother of God, to help She has granted in return, and to the peace and tranquillity which She has obtained from God.
Pope Leo XWe have devoted ourselves to the government and extension of the Church, and, among other objects, we have conceived it to be our duty to foster especially literature and the fine arts ... next to knowledge and true worship of the Creator, nothing is better or more useful to mankind than such studies.
Pope Leo XNot the Christian religion only, but nature herself, cries out against the state of slavery.
Pope Leo XIt has always been the habit of Catholic in danger and in troublous times to fly for refuge to Mary, and to seek for peace in Her maternal goodness; showing that the Catholic Church has always, and with justice, put all her hope and trust in the Mother of God. And truly the Immaculate Virgin, chosen to be the Mother of God and thereby associated with Him in the work of man's salvation, has a favour and power with Her Son greater than any human or angelic creature has ever obtained, or ever can gain
Pope Leo XAs far as Martin [Luther] himself is concerned, O good God, what have we overlooked or not done? What fatherly charity have we omitted that we might call him back from such errors?
Pope Leo XNo person shall preach without the permission of his Superior. All preachers shall explain the Gospel according to the Fathers. They shall not explain futurity or the times of Antichrist!
Pope Leo XIf the Almighty in his mercy allows us to settle peace among the christian leaders, we shall press on not only to destroy completely the bad seeds, but also to expand the territories of Christ, and, supported by these achievements, we shall go forward, with God favouring his own purposes, to the most holy expedition against the infidels, the desire for which is deeply fixed in our heart.
Pope Leo XThere are many, and there will be many, who will gladly purchase eternal life for a small price, if they see that others are fighting for God in earnest, rather than pretending to do so.
Pope Leo XTo deny that in a child after baptism sin remains is to treat with contempt both Paul and Christ.
Pope Leo XGive heed to the cause of the holy Roman Church, mother of all churches and teacher of the faith, whom you by the order of God, have consecrated by your blood. Against the Roman Church, you warned, lying teachers are rising, introducing ruinous sects, and drawing upon themselves speedy doom. Their tongues are fire, a restless evil, full of deadly poison. They have bitter zeal, contention in their hearts, and boast and lie against the truth.
