The History of the Decline and Fall of the Roman Empire - Edward Gibbon [1947]
[Footnote *: "God," says the abbot Guibert, "invented the crusades as a new way for the laity to atone for their sins and to merit salvation." This extraordinary and characteristic passage must be given entire. "Deus nostro tempore praelia sancta instituit, ut ordo equestris et vulgus oberrans qui vetustae Paganitatis exemplo in mutuas versabatur caedes, novum reperirent salutis promerendae genus, ut nec funditus electa, ut fieri assolet, monastica conversatione, seu religiosa qualibet professione saeculum relinquere congerentur; sed sub consueta licentia et habitu ex suo ipsorum officio Dei aliquantenus gratiam consequerentur."

As the manners of the Christians were relaxed, their discipline of penance ^22 was enforced; and with the multiplication of sins, the remedies were multiplied. In the primitive church, a voluntary and open confession prepared the work of atonement. In the middle ages, the bishops and priests interrogated the criminal; compelled him to account for his thoughts, words, and actions; and prescribed the terms of his reconciliation with God. But as this discretionary power might alternately be abused by indulgence and tyranny, a rule of discipline was framed, to inform and regulate the spiritual judges. This mode of legislation was invented by the Greeks; their penitentials ^23 were translated, or imitated, in the Latin church; and, in the time of Charlemagne, the clergy of every diocese were provided with a code, which they prudently concealed from the knowledge of the vulgar. In this dangerous estimate of crimes and punishments, each case was supposed, each difference was remarked, by the experience or penetration of the monks; some sins are enumerated which innocence could not have suspected, and others which reason cannot believe; and the more ordinary offences of fornication and adultery, of perjury and sacrilege, of rapine and murder, were expiated by a penance, which, according to the various circumstances, was prolonged from forty days to seven years. During this term of mortification, the patient was healed, the criminal was absolved, by a salutary regimen of fasts and prayers: the disorder of his dress was expressive of grief and remorse; and he humbly abstained from all the business and pleasure of social life. But the rigid execution of these laws would have depopulated the palace, the camp, and the city; the Barbarians of the West believed and trembled; but nature often rebelled against principle; and the magistrate labored without effect to enforce the jurisdiction of the priest. A literal accomplishment of penance was indeed impracticable: the guilt of adultery was multiplied by daily repetition; that of homicide might involve the massacre of a whole people; each act was separately numbered; and, in those times of anarchy and vice, a modest sinner might easily incur a debt of three hundred years. His insolvency was relieved by a commutation, or indulgence: a year of penance was appreciated at twenty-six solidi ^24 of silver, about four pounds sterling, for the rich; at three solidi, or nine shillings, for the indigent: and these alms were soon appropriated to the use of the church, which derived, from the redemption of sins, an inexhaustible source of opulence and dominion. A debt of three hundred years, or twelve hundred pounds, was enough to impoverish a plentiful fortune; the scarcity of gold and silver was supplied by the alienation of land; and the princely donations of Pepin and Charlemagne are expressly
