I don't think you can generalize all Mormons into Masons or all lying for a living. There are good and bad people in every religion. If the Christopher's are lying and destroying the business, they are definitely not living their religion.
I do have Dr. Christopher's School of Natural Healing book. I bought a used copy awhile back and wonder if it has been changed. It is the Tenth Printing November 1992. I sure hope it's still as Dr. Christopher wrote it. I had no idea the family was changing things until several years back I did call to get some advice on the day they take free calls. I had a question about their new calcium formula without the comfrey and when they told me it was actually better without comfrey and with nettle instead, I knew something was wrong.
