The years 1575–77 saw a great increase in tensions among Spanish Carmelite friars over the reforms of Teresa and John. Since 1566 the reforms had been overseen by Canonical Visitors from the Dominican Order, with one appointed to Castile and a second to Andalusia. The Visitors had substantial powers: they could move members of religious communities from one house to another or from one province to the next. They could assist religious superiors in the discharge of their office, and could delegate superiors between the Dominican or Carmelite orders. In Castile, the Visitor was Pedro Fernández, who prudently balanced the interests of the Discalced Carmelites with those of the nuns and friars who did not desire reform.
