Counter-Reformation
The Catholic Church’s 16th- and 17th-century movement to reform its institutions and doctrine while opposing the spread of Protestantism.
Council of Trent: An ecumenical council held in sessions from 1545 to 1563 that clarified Catholic doctrine and enacted reforms. Its decrees defined the movement’s central doctrinal and disciplinary program.
Protestant Reformation: A 16th-century movement that broke Western Christianity’s unity and established Protestant churches. Its rapid expansion prompted Catholic leaders to defend doctrine and reform institutions.
Pope Paul III: Pope from 1534 to 1549 who convened the Council of Trent and supported Catholic reform. He initiated the council that became the movement’s principal legislative body.
Lutheranism: A Protestant tradition rooted in Martin Luther’s teachings on salvation, scripture, and church authority. Its doctrines were directly contested in Catholic statements at Trent.
Baroque: A European artistic style marked by dramatic movement, rich detail, and emotional intensity, flourishing from the late 16th century. Catholic patrons used its visual drama to communicate religious devotion and doctrine.
Jesuits: A Catholic religious order founded in 1540, known for education, missions, and service to the pope. Their schools and missions became major instruments of Catholic renewal.
Martin Luther: A German theologian whose criticism of indulgences and church authority helped launch the Protestant Reformation. His challenge made doctrinal disputes impossible for Catholic authorities to ignore.
Pope Pius V: Pope from 1566 to 1572 who implemented Tridentine reforms and promoted stricter Catholic discipline. His pontificate put the council’s decrees into practice.
Calvinism: A Protestant tradition shaped by John Calvin’s theology of divine sovereignty, predestination, and church discipline. Its theology offered a prominent rival to Catholic teaching on grace and authority.
Roman Catholic Church: The largest Christian church, led by the pope and organized around Catholic doctrine and sacramental practice. The movement strengthened the church’s institutions and clarified its identity.
