"Let us praise God and give Him thanks, because our lord and head repents that he had subscribed to that heresy." This produced an uproar, challenging Bruno's claim that investiture was a heresy, and claiming that Paschal had come to an agreement with King Henry under duress. Return to the diocese Bruno's chastising the pope led to the frustrated Paschal II in turn chastising Bruno for shirking his duties, and obliged him to resign his position as the abbot of Montecassino and return to Segni as its bishop. Paschal sent a letter to the monks of Montecassino, ordering them to cease their obedience to Bruno and to proceed to elect a new abbot. Abbot Bruno departed Montecassino on 13 October 1111, and was succeeded by Abbot Gerardus on 17 October 1111. Bruno once made a serious error when he claimed that priests who committed simoniacal acts could not perform the Sacraments but he was proven to be wrong since it did not undo the sacrament of ordination despite how severe it was. When Pope Paschal died on 21 January 1118, he was succeeded by Paschal's chancellor and supporter, Cardinal Giovanni Gaetani (Gelasius II, which left Bruno's situation unchanged. The signing of the Concordat of Worms on 23 September 1122, and its ratification by Pope Calixtus II at the First Lateran Council on 27–30 March 1123, ended the discussion over lay investiture. Bishop Bruno died at Segni in mid-1123, on 3 July or 31 August, and was buried in the cathedral. His feast day as a saint, 18 July, is sometimes taken as his date of death. Cardinal ? There is a dispute as to whether or not Bruno had been made a cardinal. It is said that he declined the cardinalate, while other sources suggest he had been made the Cardinal-Bishop of Segni even though the suburbicarian diocese had not existed at that stage. Some scholars suggest that Urban II named him as cardinal in 1086, while others believe that he was named a cardinal on 18 July 1079. Works Bruno's published works are considered to be exegetical for the most part. He condemned simoniacal practices in a document written prior to 1109 entitled Libellus de simoniacis. He authored commentaries on the Book of Job and the Psalms as well as on the four Gospels. Bruno also wrote on the lives of Pope Leo IX and Pietro di Anagni. There
