Reformation to the Enlightenment (1500 CE – 1800 CE)
Meet the theologians who defended and renewed Catholic faith in an age of division. From the Council of Trent to the eve of the French Revolution, these thinkers responded to Protestant challenges, developed spiritual theology, and engaged with Enlightenment philosophy.
Counter-Reformation andCatholic Renewal
The Protestant Reformation demanded a Catholic response, and the Church produced theologians equal to the challenge. The Council of Trent clarified doctrine on justification, the sacraments, and Scripture, while a new generation of controversialists defended Catholic teaching with learning and vigour.
St Robert Bellarmine became the foremost Catholic apologist; St Peter Canisius wrote catechisms that formed generations of Catholics; Francisco Suárez developed Jesuit scholasticism. Meanwhile, the Carmelite reformers St Teresa of Ávila and St John of the Cross scaled the heights of mystical theology, while St Francis de Sales made holiness accessible to laypeople.
As the Enlightenment challenged traditional faith, Catholic thinkers engaged with new philosophical currents. Blaise Pascal offered a profound apologetic in his Pensées, while St Alphonsus Liguori developed moral theology that balanced rigour with pastoral compassion. These theologians equipped the Church to face modernity.
