During her years at Zaragoza, Maria Angela served as mistress of novices (1614-1623); teacher of young professed (1623-1626); and Abbess (1626-1642), for which it was necessary to ask for dispensation to Rome because she was not of the canonical minimum age.
Other tasks performed by sister Maria Angela included meeting those who approached the monastery asking for advice or looking for consolation, including some bishops and Cardinal Teodoro Trivulzio, Aragon Viceroy, who would maintain the epistolary relationship to return to Italy.
