According to Archbishop Flavio Pace and Bishop Anthony Ball, the relationship between Catholics and Anglicans is strengthened by fraternity and hope.
In a historical context, the bodies of Queen Elizabeth I and her half-sister, Queen Mary I (Tudor), were laid to rest in the same grave at London's Westminster Abbey, despite being divided by their religious affiliations.
This Supremacy was briefly repealed during the reign of the Catholic Mary, but was re-established during the reign of the Protestant Elizabeth.
