The Treasures of Other Traditions

The book is catholic in the sense that it respects the beliefs and practices of the historic churches. Truths about the Spirit are scattered throughout segments of a divided church and ought to be gathered from anywhere and everywhere. We are bound in the Spirit to believers of every continent and every century. Therefore I have dipped into the treasures of Catholic and Orthodox traditions in ways that I had not done before and have found affinities that surprised and delighted me.
