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 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 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 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 X
