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.
