In this book, Jacques Maritain takes a stand on the ecclesial challenges of his time and shares his own experience of the council and the post-council, unafraid to call things by their name and to express his ideas clearly.

At a time when the interpretation of the conciliar documents is being questioned, and where approaches highlighting both continuities and ruptures coexist, this work stands as one of the most important, respected, and early contributions to the debate.

However, the value of Maritain's work is not only reactive but also prospective. In much of his essay, he focuses on the "true new fire" and seeks to point out the paths to inner renewal. In this way, he also addresses the generations of his time. His message, still relevant today, offers a horizon that can continue to inspire and guide us toward new perspectives.
