Finally, Terès took part in the formation of the cathedral chapter, and later, in the delimitation of the new diocese, together with the abbot of Poblet and President of Catalonia Francesc Oliver de Boteller. In 18 September 1594, Terès travelled on board, escorted by eight galleys, to the island of Ibiza, then territory of the archdiocese of Tarragona. During the trip, the expedition was assaulted by three Muslim pirate galleys. Finally, the archbishop's galleys took over two pirate ships. He protected several orders of friars, like the Capuchins, the Augustinians and the Carmelites, and he notably improved the monastery of the Jesuits. While being archbishop he celebrated and presided the provincial ecumenical councils of 1587, 1591–92, 1598 y 1602. On 4 April 1596, Terès proceeded to the recognition ceremony of the sepulcher of the Blessed Raymond of Penyafort, who later Terès promoted his canonization, by archbishop Terès, the bishop of Barcelona, Joan Dimas Loris,and the bishop of Vic, Pere Jaume, all three commissioned by Pope Clement VIII. There were also present the bishop of Elne, Francesc Robuster i Sala, the recently appointed first bishop of Solsona, Lluís Sanç i Manegat, and the deputies of Catalonia and consuls of Barcelona. Terès also promoted the beatification of the founder of the Society of Jesus, Ignatius of Loyola. In 1602, the petronel-armed bandits Pere Voltor and Miquel Català killed Royal commissioner Epifani Olives i Terès, the archbishop's nephew, in the Castle of Valls. The jurors of Valls and many prominent authorities of the city were declared accomplices by the Royal Audience of Catalonia. This made the relations between the authorities of Valls and Terès very tense. Terès alerted the bishops not to tolerate preaching in languages other than their mother tongue. He also promoted the art of printing in Tarragona. In 1599, the King Philip III of Spain attended a session at the Catalan Courts. Terès, still archbishop, presided the ecclesiastical arm. After every session, the agreements achieved were usually printed, but that time there were five articles with which the deputies could not come to an agreement. Among them, the right of the viceroy to make proclamations and the deprivation for nobles and their servants of carrying petronels, in order to suppress banditry in Catalonia.
