The Catholic Reformation is a story often overlooked by Protestants. In this issue of Christian History magazine, read how some Catholics embraced "evangelical" ideas and helped usher in a new era. From Ignatius of Loyola and the founding of the Jesuits to the Council of Trent’s far-reaching decrees, the church returned to a focus on piety and prayer, often expressed through vibrant art. You’ll find plenty of beautiful art in these pages, alongside the struggle to address abuses, the devastating Thirty Years’ War, and Protestants dividing and immigrating. We conclude our four-part series of Reformation issues with a forum on ecumenical dialogue between Catholics and Protestants today.
