Saint Bernard of Clairvaux (1091–1153) was delegated by the Pope to preach the Second Crusade. Around 1145 he gave a sermon, partially reproduced by Joseph-François Michaud in his reference work, Histoire des Croisades, which we have taken from Bartleby.com, Great books online :
Saint Bernard of Clairvaux. Painting by Vicente Berdusán Osorio.
You cannot but know that we live in a period of chastisement and ruin; the enemy of mankind has caused the breath of corruption to fly over all regions. We behold nothing but unpunished wickedness. The laws of men or the laws of religion have no longer sufficient power to check depravity of manners and the triumph of the wicked.
The demon of heresy has taken possession of the chair of truth, and God has sent forth His malediction upon His sanctuary.
Oh, ye who listen to me, hasten then to appease the anger of Heaven, but no longer implore His goodness by vain complaints. Clothe not yourselves in sackcloth, but cover yourselves with your impenetrable bucklers.

If it were announced to you that the enemy had invaded your cities, your castles, your lands; had ravished your wives and your daughters, and profaned your temples—which among you would not fly to arms?
Well, then, all these calamities, and calamities still greater, have fallen upon your brethren, upon the family of Jesus Christ, which is yours. Why do you hesitate to repair so many evils—to revenge so many outrages? Will you allow the infidels to contemplate in peace the ravages they have committed on Christian people?
Remember that their triumph will be a subject for grief to all ages and an eternal opprobrium upon the generation that has endured it. Yes, the living God has charged me to announce to you that He will punish them who shall not have defended Him against His enemies. Fly then to arms; let a holy rage animate you in the fight, and let the Christian world resound with these words of the prophet, “Cursed be he who does not stain his sword with blood!”
If the Lord calls you to the defense of His heritage think not that His hand has lost its power. Could He not send twelve legions of angels or breathe one word and all His enemies would crumble away into dust?
But God has considered the sons of men, to open for them the road to His mercy. His goodness has caused to dawn for you a day of safety by calling on you to avenge His glory and His name. Christian warriors, He who gave His life for you, today demands yours in return. These are combats worthy of you, combats in which it is glorious to conquer and advantageous to die.
Illustrious knights, generous defenders of the Cross, remember the example of your fathers who conquered Jerusalem, and whose names are inscribed in Heaven. Abandon then the things that perish, to gather unfading palms, and conquer a Kingdom which has no end.
