When King Gundobald gave form and shape to the battle ordeal in digesting the Burgundian laws, Avitus, Bishop of Vienne, remonstrated loudly against the practice as unjust and unchristian. A new controversy arose on the occasion of the duel between the Counts Bera and Sanila, to which allusion has already been made as one of the important events in the reign of Louis le Débonnaire. St. Agobard, Archbishop of Lyons, took advantage of the opportunity to address to the Emperor a treatise in which he strongly deprecated the settlement of judicial questions by the sword; and he subsequently wrote another tract against ordeals in general, consisting principally of scriptural texts with a running commentary, proving the incompatibility of Christian doctrines with these unchristian practices.[695] Some thirty-five years later the Council of Valence, in 855, denounced the wager of battle in the most decided terms, praying the Emperor Lothair to abolish it throughout his dominions, and adopting a canon which not only excommunicated the victor in such contests, but refused the rights of Christian sepulture to the victim.[696] By this time the forces of the church were becoming consolidated in the papacy, and the Vicegerent of God was beginning to make his voice heard authoritatively throughout Europe. The popes accordingly were not long in protesting energetically against the custom. Nicholas I. denounced it vigorously as a tempting of God, unauthorized by divine law,[697] and his successors consistently endeavored, as we have already seen, to discredit it. In the latter half of the twelfth century, Peter Cantor argues that a champion undertaking the combat relies either on his superior strength and skill, which is manifest injustice; or on the justice of his cause, which is presumption; or on a special miracle, which is a devilish tempting of God.[698] Alexander III. decided that a cleric engaging in a duel, whether willingly or unwillingly, whether victor or vanquished, was subject to deposition, but that his bishop could grant him a dispensation provided there had been loss of neither life nor limb.[699] Towards the close of the century Celestine III. went further, and in the case of a priest who had put forward a champion who had slain his antagonist he decided that both principal and champion were guilty of homicide and the priest could no longer perform his functions, though he might have a dispensation to hold his benefice.[700] These cases suggest one of the reasons why the repeated papal prohibitions were so ineffective. The all-pervading venality of the Church of the period found in the dispensing power an exhaustless source of profit, and dispensations for “irregularities” of all kinds were so habitually issued that the threatened punishments lost their terrors, and as Rome gradually absorbed the episcopal jurisdiction, offenders of all kinds knew that relief from the operation of the canons could always be had there.
