A third important difficulty concerned the position of the regular clergy (non-order affiliated) and their privileges. Adrian VI on May 9, 1522, issued the bull "Exponi nobis fecisti" to Charles V, in which he transferred his own Apostolic authority in all matters to the Franciscans and other mendicant orders when they judged it necessary for the conversion of the Indians, except for acts requiring episcopal consecration. This provision affected regions where there was no bishop, or where it required two or more days of travel to reach one. Pope Paul III confirmed the bull on January 15, 1535. The bishops found their authority much limited, and a series of assemblies followed in which Zumárraga with his customary prudence tried to arrive at an understanding with the regulars without openly clashing with them. Various modifications were adopted with the consent of the regulars on condition that these "should not impair the privileges of the regulars". The question therefore remained open. In 1535, Bishop Zumárraga received the title and powers of Apostolic Inquisitor of the diocese of Mexico from the Inquisitor General, Álvaro Manrique, Archbishop of Seville, including that of delivering criminals to the secular courts. He never availed himself of the title and did not establish the tribunal, although he did indict and deliver to the secular courts a lord of Texcoco, known as Don Carlos Ometochtzin Chichimecatecuhtli, accused of having "reverted to idolatry" and of offering human sacrifices.
