Poland was equally remiss in enforcing the canons on her clergy. The leaning of the Slavonic races towards the Greek church rendered them, in fact, peculiarly intractable, and marriage was commonly practised by the clergy at least until the close of the twelfth century.[599] At length the efforts of Rome were extended to that distant region, and in 1197 the papal legate, Cardinal Peter of Capua, held the synod of Lanciski, when the priests were peremptorily ordered to dismiss their wives and concubines, who, in the words of the historian, were at that time universally and openly kept.[600] The result of this seems to have amounted to little, for in 1207 we find Innocent III. sharply reproving the bishops of the province of Gnesen because married men were publicly admitted to ecclesiastical dignities, and canons took no shame in the families growing up around them. The children of priests were brought up to the sacred profession of their fathers, assisted them in their ministrations, and succeeded to their benefices. Whether or not the other disorders which Innocent designated as infecting the churches were the result of the carnal affections which thus superseded the spiritual we may fairly doubt, in view of the abuses still prevailing in more favored regions.[601] The effort was continued, and was apparently at length successful, at least in the western portions of the Polish church, for at the council of Breslau, held in 1279, there is no mention of wives, and the constitution of Guido, legate of Clement IV., is quoted, depriving of benefices those who openly kept concubines.[602] * * * * *
