Denis, it was resolved to open Charles’s tomb. The only tenant of the sepulchre was found to be a serpent, and the walls were blackened as though by fire, thus proving the truth of the revelation, and holding out an awful warning to future wrongdoers.[287] How much of the license complained of was indiscriminate concubinage, and how much was merely intercourse with legitimate wives, we have no means of ascertaining. The latter Boniface succeeded in suppressing, for the church could control her sacraments.[288] The former was beyond his power. Armed with full authority from Pope Zachary, Carloman and Boniface commenced the labor of reducing to order this chaos of passion and license. Under their auspices a synod was held, April 23, 742, in which all unchaste priests and deacons were declared incapable of holding benefices, were degraded and forced to do penance. Bishops were required to have a witness to testify to the purity of their lives and doctrines, before they could perform their episcopal functions. For all future lapses from virtue, priests were to be severely whipped and imprisoned for two years on bread and water, with prolongation of the punishment at the discretion of their bishops. Other ecclesiastics, monks, and nuns were to be whipped thrice and similarly imprisoned for one year, besides the stigma of having the head shaved. All monasteries, moreover, were to adopt and follow rigidly the rule of St. Benedict.[289] The stringency of these measures shows not only the extent of the evil requiring such means of cure, but the fixed determination of the authorities to effect their purpose. The clergy, however, did not submit without resistance. It is probable that they stirred up the people, and that signs of general disapprobation were manifested at a rigor so extreme in punishing faults which for more than two generations had passed wholly unnoticed, for during the same year Zachary addressed an epistle to the Franks with the object of enlisting them in the cause. The ill-success of their arms against the Pagans he attributes to the vices of their clergy, and he promises them that if they show themselves obedient to Boniface, and if they can enjoy the prayers of pure and holy priests, they shall in future have an easy triumph over their heathen foes.[290] Yet many adulterous priests and bishops, noted for the infamy of their lives, pretended that they had received from Rome itself dispensations to continue in their ministry—an allegation which Zachary of course repelled with indignation.[291] Carloman, however, pursued his self-imposed task without flinching. On March 1st, 743, he held another synod at Leptines, where the clergy promised to observe the ancient canons, and to restore the discipline of the church. The statutes enacted the previous year were again declared to be in full vigor for future offences, while for previous ones penitence and degradation were once more decreed.[292]
