A few years ago, my mother in-law sent me the hardcover version of "Secret Ceremonies," wanting to know how I, as a former Mormon, felt about it. While I found parts of it "inaccesible," others were certainly resonated with my experiences as a woman in the LDS church.
My husband thought my own stories might be slightly exagerated, until we went to Utah for a wedding and he had difficulty finding a place where he could get a cup of coffee. We finally found a tiny coffee house, reminiscent of a prohibition-era "speak-easy," owned and patronized by the town's few defiant java-loving rebels. He was also amazed as we stood outside the temple, watching couples and families swarm in and out, "like a marriage assembly-line," as he put it.
In my opinion, the LDS "perfection is not only possible in this lifetime, but expected" doctrine, as well as the minute demands on every aspect of one's life, contributes to serious problems for a significant portion of its membership, particularly among those who are perceived as "different" in any way. this includes strong-willed women, who are seen by some LDS men as needing to be "broken".
In spite of these things, I don't generally reguard Mormons as "bad" people. Rather,(again, "in my opinion") many of them are caught up in thier doctrinal and cultural views to such a degree that they are incapable of understanding how insensitive, unreasonable and offensive their behavior can seem to "outsiders."
If you're a "recovering Mormon," you might find "Secret Ceremonies" worth reading, even healing. If you have little or no experience with the LDS church, it could provide an alternate, "unauthorized" glimpse into a very different American culture. If you're a practicing Mormon you'll likely only be upset by this book, so my advice would be to spare yourself the pain and anger.
