His teaching was simply antisacerdotal--to some extent a revival of the errors of Claudius of Turin. Pædo-baptism was useless, for the faith of another cannot help him who cannot use his own--a far-reaching proposition, fraught with immeasurable consequences. For the same reason offerings, alms, masses, prayers and other good works for the dead are useless and each will be judged on his own merits. Churches are unnecessary and should be destroyed, for holy places are not wanted for Christian prayer, since God listens to those who deserve it, whether invoked in church or tavern, in temple or market-place, before the altar or before the stable; and the Church of God does not consist of a multitude of stones piled together, but in the united congregation of the faithful. As for the cross, as a senseless thing it is not to be invoked with foolish prayers, but is rather to be destroyed as the instrument on which Christ was cruelly tortured to death. His most serious error, however, was his rejection of the Eucharist. Transubstantiation had not yet had time to become immovably fixed in the perceptions of all men, and Pierre de Bruys went even further than Berenger of Tours. His only recorded utterance is his vigorous rejection of the sacrament: "O people, believe not the bishops, the priests, and the clerks, who, as in much else, seek to deceive you as to the office of the altar, where they lyingly pretend to make the body of Christ and give it to you for the salvation of your souls. They plainly lie, for the body of Christ was but once made by Christ in the supper before the Passion, and but once given to the disciples. Since then it has been never made and never given."[52] There was evidently nothing to do with such a man but to burn him, but even this did not suffice to suppress his heresy. The Petrobrusians continued to diffuse his doctrines, secretly or openly, and, some five or six years after his death, Peter the Venerable of Cluny considered them still so formidable as to require his controversial tract, to which we are indebted for almost all we know about the sect. This is dedicated to the bishops of Embrun, Arles, Die, and Gap, and urges them to renewed efforts for the suppression of the heresy by preaching and by the arms of the laity.
