"Who, then, in a case of such great emergency shall refuse to pay obedience to Jesus Christ? When he comes to stand before Christ's tribunal to be judged, what answer will he be able to make to him in defense of himself? If God has submitted himself to death for man, is man to hesitate to submit to death for God? ... Shall then the servant deny temporal riches to his lord when his lord bestows on the servant riches that are eternal. ... Let each and all, then, prepare themselves so that in the next month of March each city by itself and...each of the earls and barons should...send a number of warriors to the defense of the land of the nativity of our Lord. ... we especially conceive as one of our chief concerns our desire to apply every energy to the rescue of the lands of the East."

“O how great a benefit will result from this cause; how many, converted to penitence, have handed themselves over by service of the Crucified for the liberation of the Holy Land, as is by suffering martyrdom they have obtained the crown of glory, who would perhaps have perished in their iniquities entangled in carnal desires and earthly seductions. This is an old device of Jesus Christ that he deigned to renew in these days for the salvation of his faithful. .. Thus the King of kings, our Lord Jesus Christ, who brought body and soul and other goods to you, will condemn you for the vice of ingratitude and the crime of infidelity if you should fail to aid him with the result that he lost his kingdom that he brought with the price of his blood.”

“For behold, our inheritance has gone to strangers, our houses to alien people. ... The sepulcher of the Lord, which the prophet foretold should be so glorious, has been profaned by the unrighteous and has thereby been made inglorious. ... Take, therefore, my sons, the spirit of fortitude, the shield of faith, and the helmet of salvation, putting your trust in God, not in numbers nor in your strength, but rather trusting in the power of God, to whom it is not difficult to save either with many or the few.”

“After the wretched fall of the kingdom of Jerusalem, after the lamentable slaughter of the people of Christendom, after the deplorable invasion of that land on which the feet of Christ had stood, and where God, our King, had deigned to work our salvation in the midst of the earth, after the ignominious removal of the life-giving cross on which the salvation of the world had been hanged, and thereby blotted out the signature of the old death, the Apostolic See, alarmed at the awful recurrence of disasters so unfortunate, was struck with agonizing grief, exclaiming and bewailing to such a degree that, from her continual crying, her throat became hoarse. ... Still the Apostolic See cries aloud, and she raises her voice like a trumpet, trying to arouse the nations of Christendom to fight the battles of Christ, and to avenge the injuries done to him crucified.”

“...the Christian people possessed almost all the Saracen provinces until after the time of Saint Gregory. But after that time, a certain son of perdition, the pseudo-prophet Muhammad, arose, and he seduced many away from the truth with carnal enticements and pleasures. Even though his perfidy lasted until the present, still we trust in the Lord who has now made a good sign that the end of this beast, whose number, according to John's Apocalypse, counts 666, of which now almost six hundred years are completed approaches. ... Therefore, dearly beloved sons, changing dissensions and fratricidal jealousies into treaties of peace and goodwill, let us gird ourselves to come to the aid of the Crucified, not hesitating to risk property and life for him who laid down his life and shed his blood for us.”

“Know then that whoever denies aid to the Redeemer in this time of his need is culpably harsh and harshly culpable. For, also, insofar as, according to the divine command, he loves his neighbor as himself and for him, he knows that this brethren in faith and in the Christian name are imprisoned by the faithless Saracens in a cruel prison and endure the harsh yoke of slavery, he does not expend the efficacious work for their liberation, that the Lord spoke of in the Gospel. "Do to others whatever you wish them to do to you". Or perhaps you do not know that many thousands of Christians are held in prison and slavery by them and they suffer countless torments?”
