End of Protestantism

Peter Leithart's The End of Protestantism emerges from his conviction that the Protestant Reformation, while historically necessary, has outlived its usefulness and now perpetuates the very divisions it once sought to address. Writing as a Reformed theologian who has wrestled deeply with questions of church unity and denominational identity, Leithart argues that Protestantism's foundational protest against Rome has calcified into an institutional structure that inhibits rather than promotes Christian unity and mission.

Leithart contends that Protestantism was never meant to be a permanent ecclesiastical arrangement but rather a reforming movement within the broader Catholic church. He traces how the original Protestant principle of semper reformanda has been abandoned in favor of confessional entrenchment and denominational self-preservation. The book argues that contemporary Protestantism has become what he calls "Reformational Catholicism" in reverse—a collection of competing magisteria that claim authority while fragmenting the visible church. Leithart proposes that faithful Christians should work toward what he terms "Reformational Catholicity," a reunified church that maintains Reformation insights about Scripture and grace while recovering visible unity and apostolic order. This involves neither a return to medieval Catholicism nor a simple merger of existing denominations, but a fundamental reconceptualization of what it means to be the church in apostolic succession.

The work has sparked considerable debate within Reformed and broader Protestant circles, with critics arguing that Leithart underestimates the theological barriers to reunion and supporters praising his willingness to challenge Protestant assumptions about ecclesiology. His argument represents a significant voice in contemporary discussions about Christian unity and the future of denominationalism.

Who should read this: Reformed and Protestant readers willing to have their assumptions about church structure challenged will find this most valuable, particularly those involved in ecumenical discussions or wrestling with questions of denominational loyalty. Readers seeking to defend traditional Protestant distinctives or looking for practical steps toward reunion may find the work frustrating.
