Who they were

At Ourém in Portugal, Saint Teresa, who, queen of León and mother of three children, after the death of her husband led the monastic life under Cistercian discipline in the monastery she herself had founded.

The miracles

The Roman Martyrology does not describe the miracles approved in the cause.

Why that counted as sanctity

The Roman Martyrology remembers her on 17 June as a queen of León who became a Cistercian nun in the monastery she founded.

The cause

The cause continues. No postulation address is published here yet. Favours received through this person’s intercession, and offers of help, are best sent to the religious order or congregation they belonged to, or to the diocese where the cause was opened; either will pass them to the postulation.

A miracle approved by the Holy See is needed for the next step. If you know the postulation’s own page, tell us and it will be added here.
