The continuous wars between Spain and Portugal had created a terrible relationship between the two countries since 1633.  This affected the appointment of a bishop for Macao.  So, it was for 80 years that the diocese of Macao was without a bishop until 1690 when Bishop João de Casal was appointed.  He came to Macao in 1692.  During that time, many places had already set up their own diocesan affairs of its own city and a few nearby regions.  Bishop Casal set up "O Cabido" as the Board of Diocesan Consulters in 1698.  He died in Macao in 1735 after 45 years of service as Bishop of Macao, and was buried in the Cathedral.
