Sister Teresa entered the Monasterio de Buenafuente del Sistal on the very day of Benedict’s birth, 16 April 1927. Aside from a distraction of the Spanish Civil War (1936-39) that caused the nuns to flee fighting, Sister Teresa has lived her vocation as a cloister nun in that place.
A journalist for El Mundo, Jesús García, authored a book about 10 nuns, of whom Sister Teresa was included, titled, ¿Qué hace una chica como tú en una sitio como éste? (2011; What is a Girl Like You Doing In A Place Like This?)
Sister’s monastery was founded in the 13th century, and for 20 years was the religious superior.
