This 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 XTo deny that in a child after baptism sin remains is to treat with contempt both Paul and Christ.
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 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.
Pope Leo XArise, 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 X
