This book became a horrible frustration for me to read. It started out well enough, but there were such gaps and glaring omissions and confusing logic that by the end I could barely read two pages in a row without having to put the book down. There are a few poignant points, which saves this book from getting one star, but overall this book doesn't say much that better books have said much better.
Henri Nouwen explains from the outset that this book is written to explain the spiritual life to secular people, specifically to fulfill the request of his secular Jewish friend to write a book that he and his friends "could hear." I was surprised and disappointed to discover that Nouwen answered this request in a narrow-minded, specific focus rather than trying to speak to the secular world at large. There are so many direct references that are specific to his friend's life and/or assume great familiarity with Jewish spiritual life and scriptures that I can't imagine this being that helpful to people who don't have a Judeo-Christian background that they are decently familiar with. Add to this lofty, flowery language about basically everything Nouwen talks about, and the book ends up a deeply-coded mess that is more suited for deeply spiritual believers.
The biggest and most egregious offense to me came because I was expecting this book to explain the CHRISTIAN life and reality to secular people. It wasn't an unreasonable expectation, as Nouwen speaks of having written other books that "were so explicitly Christian and so clearly based on a long life in the church" (20) that his friend couldn't find much support in them. But in his attempt to speak to his friend, Nouwen swings the pendulum too far the other way and completely omits any facet of the spiritual life that has to do with the Gospel. I kept waiting for him to talk about our sin, our need for a Savior, and how Jesus makes it possible for us to understand and fully accept this title of 'Beloved,' but none of those important words or concepts are even brushed upon in this book. Also absent is any kind of admonition or instruction on how or why the Christian life is lived differently as a result of this transforming love reality. The Christian life is completely devoid of its power without the truth of Christ, and so is this book. As a Christian, there were nuggets I could glean and, through the lens of my biblical and spiritual understanding, apply to my life, because through the Gospel I have experienced the acts of love that make Nouwen's words ring true. I would imagine someone without Judeo-Christian training or a lens to view the world or reality in a Christ-perspective would find this book filled with gushy, feel-good platitudes that had no weight of truth, like being gifted with a guard dog that had no teeth.
Another problem with this book complementary to the absence of the Gospel is that Nouwen describes the spiritual life practically absent from God until the last chapter (not counting the epilogue). God's role is reduced to little more than the proof of how good and wonderful we all are. There is no explanation of who he is, what he wants from/for us or why we should care, and almost nothing about having a relationship with us outside of him calling us the beloved. The only worship described or prescribed in this book is the worship of ourselves, a "You can be great if you realize you are loved because you are so special and great" kind of worship that seems to be the source of all Nouwen's insight and advice about the spiritual life (in this book). There seemed to little in here to differentiate it from the kind of "love yourself" self-help offered in grocery store magazine racks, only with even more flowery language and occasional references to Old Testament texts. There is some quotable wisdom and good advice, and it is a small and quick read (if you don't have to rage-quit every few pages like I did), but it wasn't quite worth my time. The biggest benefit I got from reading this book was a greater understanding of how the facets of Christian life that Nouwen omits are integral to living the life of the Beloved.
Edit: It's been years since I read this book but I think of it fairly often as a quintessential example of a terrible, unhelpful, not-quite-heretical-but-almost-as-bad book. The memories of rage-quitting this book multiple times is so strong in my mind that it is most of what I remember (besides it being devoid of the Gospel). But now, re-reading this review, I am baffled as to what possessed me to give this anything higher than one star? It's probably only worth half a star, but that's not within my power. But it IS within my power to rectify my egregious star inflation, so now the score is that much closer to expressing my true experience.
