After leaving the military to become a monk, St. Martin of Tours played a key role in spreading monasticism across Gaul. His cloak, or “cappa” in Latin, became a sacred relic and inspired the word “chapel.” In medieval Europe, his feast day was marked with food and festivities.

St. Benedict set the stage for Western monastic life. At Monte Cassino, he founded his famous monastery and created the Benedictine Rule. Monks who followed it served as trusted teachers, and their influence stretched even into royal courts. His rule guided daily life for centuries, influencing both faith and learning across Europe.

St. Clare Of Assisi

Clare of Assisi founded the Poor Clares, a convent devoted to strict poverty and faith. She resisted pressure from popes to ease her vow of poverty. Her convent was so respected that prayer reportedly protected it from invading soldiers. She later became the first woman to write a monastic rule, and noblewomen across Europe looked to her as an example.

St. Francis Of Assisi

His preaching extended also to birds and animals and made him famous for compassion toward all creation. Later, he received the stigmata, a sign that confirmed his devotion to faith.

The push to end the Avignon Papacy and restore the papal seat to Rome came through the urging of St. Catherine of Siena, who advised Pope Gregory XI directly. Although she lived as a laywoman, the Church later declared her a saint. Also, her writings and counsel helped Catherine stand out in a silenced age.

St. Thomas Becket

Thomas Becket served as Archbishop of Canterbury and is noted for opposing King Henry II on Church rights. He was murdered inside Canterbury Cathedral by the king’s followers. After his martyrdom, however, a shrine at his tomb drew pilgrims, many even reporting miracles, making Becket’s end a turning point in Church history.

St. Hildegard Of Bingen
