The Portuguese refused to recognise Bishop de Castro's appointment and vigorously opposed his activities. Archbishop Brandão's sudden death on 6 July 1678 further complicated matters, and the Cathedral chapter administering the Archdiocese of Goa following the vacancy created by his death, forbade the Canara Catholics from receiving the sacraments from the bishop or from priests appointed by him. In his turn, Bishop de Castro excommunicated those Catholics who were obedient to the Padroado authorities in Goa and their priests. In 1681, the Holy See appointed another Goan priest Fr. Joseph Vaz, as the Vicar Forane of Canara; he was asked not to submit to Bishop de Castro unless he showed the letter of appointment. However, after being convinced of its legitimacy, Fr. Vaz submitted to Bishop de Castro and brought about a truce. He further managed to persuade the bishop to delegate his jurisdiction to him while retaining the post. In 1700, the Catholics of Canara were again brought under the jurisdiction of the Padroado Archbishop of Goa.
