Bonizo (Bonitho)

BONIZO (BONITHO): Bishop of Sutri; b. at Cremona c. 1045; d. at Piacenza July 14, probably 1090. As a young cleric he joined the Patarene movement (see Patarenes) in Cremona and Piacenza. He came to Rome in 1074, possibly in consequence of his conflict with Bishop Dionysius of Piacenza, and was himself made bishop of Sutri in 1075 or 1076. In the spring of 1078 he was in Lombardy as legate, and back in Rome by November, when he took part in the synod that discussed Berengar's teachings. A zealous partizan of Gregory VII, he was imprisoned by Henry IV in 1082 and entrusted for safe-keeping to the antipope Guibert of Ravenna (Clement III). He contrived to escape, but never returned to his see. In 1085 he found shelter with Countess Matilda, and in the summer of 1086 was chosen bishop of Piacenza by the Patarene party. His election being uncanonical, Anselm of Milan, the metropolitan, refused to install him; but he succeeded in gaining the approval of Pope Urban II in 1088 or 1089. He did not long enjoy his triumph, meeting a violent death in a rising of the imperialist party. The most important of his writings, the Liber ad amicum (ed. E. Dümmler, MGH, Libelli de lite, i, 1891), composed between the death of Gregory VII and the accession of Victor III (1085–86), besides discussing the question whether a Christian may bear arms in the defense of the Church (which he answers in the affirmative), shown by an extended historical sketch that the Church grows under persecution. The chief value of the work is due to its presentation of the ideas of Gregory and his adherents; it informs us how the papal camp judged of the numerous theological and ecclesiastico-political controversies of the time, and as a whole is one of the most noteworthy productions of the Gregorian party. Often as it has been appealed to as a contemporary source, it has to be used with caution, owing not only to carelessness and errors of detail, but to demonstrable perversions of history, as in the account of the Canossa episode. In fact, it is colored throughout by the author's subjective standpoint. The Liber in Hugonem schismaticum (presumably Cardinal Hugo Candidus) has unfortunately been lost. As a canonist Bonizo left a large Decretum in ten books, from which Mai published extracts in 1854.
