Response to Luther
Thomas More's Responsio ad Lutherum stands as one of the most sustained and personal Catholic responses to Martin Luther's early reformist writings. Published in 1523 under the pseudonym "Gulielmus Rosseus," this Latin treatise emerged from More's deep alarm at Luther's attack on King Henry VIII's Assertio Septem Sacramentorum and the broader challenge Luther posed to Catholic sacramental theology. Writing as both a humanist scholar and a committed Catholic layman, More felt compelled to defend not only his king but the entire structure of Catholic doctrine against what he saw as Luther's dangerous innovations.
More's argument proceeds through detailed refutation of Luther's positions on papal authority, the sacraments, and the nature of the Church. He employs his considerable skills as a lawyer and rhetorician to dissect Luther's logic, often with biting sarcasm and personal invective that shocked even contemporary readers. More defends the Catholic understanding of tradition as a source of divine revelation alongside Scripture, arguing that Luther's principle of sola scriptura leads inevitably to chaos and heresy. He particularly focuses on defending the sacramental system, especially the Mass and penance, against Luther's reductions. Throughout, More presents the Catholic Church as the necessary interpreter of Scripture and guardian of authentic Christian teaching, established by Christ himself through the apostolic succession.
The Responsio reveals More's intellectual formation and the mindset of Catholic humanism facing the Protestant challenge. It demonstrates how educated Catholics initially understood the Reformation as primarily a problem of individual rebellion rather than systemic reform, and it shows More's own trajectory toward the martyrdom that would define his legacy. Who should read this: scholars of Reformation controversy and those interested in the Catholic intellectual response to early Protestantism will find essential material here, though general readers may struggle with both the Latin original and More's often vitriolic rhetorical style.
