Devotio Moderna
Devotio Moderna was a Catholic religious reform movement that arose in the Low Countries during the late 14th century, initiated by the preacher Geert Groote (c. 1340–1384), emphasizing personal inner devotion, imitation of Christ's humility and suffering, and a return to apostolic simplicity amid widespread ecclesiastical corruption.[1][2] The movement promoted lay participation in spirituality through communities like the Brethren and Sisters of the Common Life, who lived communally without formal monastic vows, engaging in manual labor, education, and the copying of devotional manuscripts to foster direct engagement with scripture and meditation.[1][3] Key practices included daily routines of prayer, Bible reading, self-examination, and contempt for worldly vanities, which contrasted with scholastic theology by prioritizing experiential piety over intellectual speculation.[2][3] Its most notable achievement was the production of influential texts, such as Thomas à Kempis's The Imitation of Christ, which encapsulated the movement's call to interiorize faith and became one of the most widely read Christian works after the Bible, shaping personal devotion across Europe.[1] The Devotio Moderna expanded through affiliated houses—reaching around 50 by the mid-15th century, predominantly sisterhouses—and the Windesheim Congregation of Augustinian canons, facilitating education that influenced figures like Erasmus and even elements of later Protestant emphasis on scripture accessibility, though the movement remained firmly within Catholicism and avoided direct confrontation with church hierarchy.[2][1] Defining its character was a practical, undogmatic approach to reform, focusing on voluntary communal asceticism and spiritual renewal rather than institutional power, which earned it a reputation as a "quiet revolution" sustaining piety through turbulent times like the Black Death and conciliar crises.[2][3]
