This is a scholarly contribution to church history by a Catholic theologian who is now the head of the English Department of Clermont-Ferrand University, France. Dealing with the period extending from the fifteenth to the seventeenth century the author's thesis is that the Catholic Reformation began before the Protestant revolt as a continuation of the Christian humanist movement of the fifteenth century. The book therefore controverts the Protestant contention that the Catholic reformation was a direct result of the Protestant movement and the attention is called to the abuses within the church. This book also asserts that the admitted evil conditions in the Church were not due to error in doctrine, as Protestants declare, but to faults in organization and laxity in discipline which the Church itself corrected. Protestant Church historians will not accept the thesis of the book, but it is a well written and cogently argued presentation, of interest primarily to Church historians.
