Bartholomew often acted as a judge-delegate for the papacy in cases that had been appealed to Rome. At some point in his career, he wrote a Penitentiale, or penitential, which true to his canon lawyer training, quotes canon law extensively. Alexander described Bartholomew, in company with Richard of Dover, another leading papal judge, as the ``twin lights illuminating the English Church''. In his diocese, Bartholomew is known to have visited the parishes, conducting a visitation to inquire into the management or mismanagement of church affairs.
