Oh, I read plenty. Actually, I know all about the so-called "Peasant Crusade," and was waiting for it to come up. Well, Holysmoke's argument is that Christians use what Paul said as a way to rationalize their involvement in state-sponsored genocide. As the "peasant crusade" (if you want to differentiate it from the First Crusade, of which it is generally considered part) was a non-governmental movement, it is outside the scope of the argument, yeah? The people who went along couldn't have rationalized their involvement as simply following government orders because they weren't following the government-- unless you want to say that this was, in fact, part of the First Crusade, in which case the whole "peasantness" of it all ceases to be a factor.
By the way, what happened to those peasants? How many acts of genocide did these farmers and urban labourers perform-- BEFORE THEY WERE DESTROYED BY A PROFESSIONAL ARMY? I'll help you out: none.
Yep, reading's good....
The oxford illustrated history of the crusades by J.Riley-smith, professor of ecclesiastical history, university of cambridge -
'Above all, the church was equipped to impose a degree of systemization and consistency upon the issues which violence raised. It had inherited from Roman law, the OT and NT, and the early church fathers, pre-eminently St Augustine, various terms of reference by which to analyse instances of violence and pronounce upon their quality.' ie just war.
Gregorian Reform..'A consequence was that when pope Urban launched the 1st crusade he was able to mobilize the resources,enthusiasm and communication skills of many individual clerics and religious communities, a body of collective support which had already grown sensitive to papal initiatives. The preachers of the crusade would have been wasting their breath,of course,had not many europeans been eager to respond to what was held out as a voluntary undertaking. The crusade was proposed as a devotional act of pilgrimage, and therein lay its attraction'.
There were of course other 'holy crusades' [or political if you will, all the same in medieval times],going on in europe at the same time, concerning submission to papal authority, becoming vassals.
..'Indeed, it must be stressed that at the very time [1096] that the 1st crusades were en route to Jerusalem, Urban II quite unambiguously permitted, or rather urged, Catalan nobles who had taken the CROSS for the crusade to the East to fulfill their vows in Spain. In return for aiding the CHURCH of Tarragona, they were promised FORGIVENESS OF SINS'. [my emphasis.
'The core of all crusade promotion consisted of papal proclamation of the expedition in question since popes ALONE possessed the requisite authority to declare a crusade and offer the spiritual and material privileges enjoyed by crusaders'.
'According to the account of the council of clermont, Urban II actively sought to dissuade the elderly,the infirm,women.clerics and monks from taking crusade VOWS, a stance confirmed by his surviving letters. ..'12th century popes maintained this attitude,but unsuccessfully. Large numbers of NON-COMBATANTS took the CROSS and departed, especially on crusades to the holy land,thereby causing immense problems'.
'Urban had intended that the crusade army should consist fundamentally of knights and other ranks that would be militarily useful.However as news of what he had proclaimed at clermont spread through the west,so men and women OF ALL SOCIAL CLASSES AND OCCUPATIONS took the CROSS. Urban had lost control in the matter of personnel. One immediate consequence was the APPALLING violence unleashed against the jews of northern France and the Rhineland, the 1st of a series of pogroms and other forms of anti-semitism that would become closely associated with crusading activity in succeeding generations. Many, but by no means all,of those responsible were drawn precisely from those social groups that Urban wished to keep at home, especially bands of urban and rural POOR'.
The problem with seeing history from one perspective ie christian, is that one gets a squinted one percpectival viewpoint.
