Many rulers embraced this melding of religion with their secular roles. Robert the Pious (King of the Franks, 996 - 1031), embodied the new church policies in an oath:
I will not infringe on the Church in any way. I will not hurt a cleric or a monk if unarmed. I will not steal an ox, cow, pig, sheep, goat, ass, or a mare with colt. I will not attack a villain or villainess or servants or merchants for ransom. I will not take a mule or a horse male or female or a colt in pasture from any man from the calends of March to the feast of the All Saints unless to recover a debt. I will not burn houses or destroy them unless there is a knight inside. I will not root up vines. I will not attack noble ladies travelling without husband nor their maids, nor widows or nuns unless it is their fault. From the beginning of Lent to the end of Easter I will not attack an unarmed knight.
(Robert was so pious that he is given credit for some miraculous healings.)
Years later, when Pope Urban II wanted to call for a Crusade, he used the concept of the Peace and Truce to re-direct violent behavior from their fellow man to the Saracen:
Oh race of the Franks, we learn that in some of your provinces no one can venture on the road by day or by night without injury or attack by highwaymen, and no one is secure even at home. Let us then re-enact the law of our ancestors known as the Truce of God. And now that you have promised to maintain the peace among yourselves you are obligated to succour your brethren in the East, menaced by an accursed race, utterly alienated from God.
Not everyone believed that the Truce of God made sense. No less a theologian and scholar than St. Thomas Aquinas writing in the 13th century felt the Truce of God was unnecessarily limiting. Protecting the country was sufficiently important that it should also be fought for on feast days and holy days.
The ritual for confirming a knight included one blow, the only blow he was allowed to take without defending himself. Tomorrow let's look at the ritual and history of being slapped.
