An immensely important contribution to true interfaith discussion, this book is a generous and illuminating introduction to the genuine strengths of the Protestant movement — and a frank, charitable examination of its weaknesses. Louis Bouyer shows the value of the Protestant ideas of the sovereignty of God, justification by faith, and even the centrality of Scripture. He also looks squarely at how Protestantism has suffered from its denial of the sacraments, Church authority, and more. He challenges Catholics and Protestants alike to know their beliefs more deeply — an essential foundation to any dialogue.
Bouyer, beginning his spiritual service as a French Lutheran Cleric, knew Protestant thought from the inside out. He is careful to outline all the good Reform teaching contains and quick to point out how Church practice at the time of the Reformation had come to deemphasize much the Reformers championed. His issues are not with the orthodox doctrines but with the negative elements that mysteriously appear with them in Reform thought. Bouyer insist that these elements, not rooted in orthodox doctrine but in the poison of Occamist Nominalism, weaken and dilute the orthodox doctrines and prevent them from bearing fruit. They also create endless division and doctrinal chaos and confusion.
The book is divided into three large sections. In the first he outlines the positive principles of the Reformation, with numerous quotes from the writings of the Reformers. The second section, which is much shorter, Bouyer discusses the negative elements in Reform thought, shows their source in Occamist/Scotist Scholasticism and exposes the logical incompatibility of Occam’s Nominalism with Christian realities as they are presented in both Church Doctrine and Sacred Scripture.
The final section is essentially his solution to the dilemma of doctrinal chaos in the Protestant world.
