Who Was Blessed Adeline?
Adeline lived in the generation after the Norman conquest of England, connected to reform movements spreading from Savigny. Her brother Vitalis founded monasteries; Adeline became first abbess of the convent of White Ladies at Mortain. The community followed Benedictine observance linked to the Savigny congregation before its Cistercian absorption.
She died in the early twelfth century and was beatified for heroic virtue. Feast October 20.
The religious house at Mortain followed the Rule of St. Benedict together with a few observances drawn from the Cistercian tradition. This combination of Benedictine and Cistercian spirituality created a unique and rich spiritual environment that emphasized prayer, work, and community life.
