Father Wolf had been instructed specially to recommend to the Holy See those priests whom he deemed qualified for appointment to vacant bishoprics. This was a matter of essential importance, and as such he devoted to it his particular care. Thomas O'Herlihy was appointed to Ross (1561); Donald McCongail or Magongail, the companion of his journeys, was appointed to Raphoe (1562); the Dominicans O'Harte and O'Crean were provided to the Sees of Achonry and Elphin in the same year at his request, and during the time he remained in Ireland his advice with regard to episcopal nominations was followed as a rule. He was instructed also to establish grammar schools throughout the country, and he was not long in Ireland till he realised the necessity of doing something for education, and above all for the education of candidates for the priesthood. In 1564 he obtained from Pius IV. the Bull, /Dum exquisita/,[60] empowering himself and the Archbishop of Armagh to erect colleges and universities in Ireland on the model and with all the privileges of the Universities of Paris and Louvain. For this purpose they were empowered to apply the revenues of monasteries, and of benefices, and to make use of the ecclesiastical property generally. Unfortunately owing to the disturbed condition of the country, and the subsequent arrest of both the archbishop and the papal commissary, it was impossible to carry out this scheme. In the earlier sessions of the Council of Trent the Archbishop of Armagh had taken a leading part. When the Council opened for its final sessions in January 1562 Ireland was represented by O'Herlihy of Ross, McCongail of Raphoe, and O'Harte of Achonry. Nor were these mere idle spectators of the proceedings. They joined in the warm discussions that took place regarding the Sacrifice of the Mass, Communion under both kinds, the source of episcopal jurisdiction and of the episcopal obligation of residence, the erection of seminaries, and the matrimonial impediments. It is said that it was mainly owing to their exertions that the impediment of spiritual relationship was retained.[61] After their return attempts were made to convoke provincial synods to promulgate the decrees of the Council of Trent. In 1566 apparently some of the prelates of Connaught assembled and proclaimed them in the province of Tuam; in 1587 the Bishops of Clogher, Derry, Raphoe, Down and Connor, Ardagh, Kilmore, and Achonry, together with a large number of clergy met in the diocese of Clogher for a similar purpose, and in 1614 they were proclaimed for the province of Dublin by a synod convoked at Kilkenny.[62]
