Ban this book?

Got a brochure today from Ave Maria Press - pretty mainstream. They were advertising a book called God Has No Religion which is a prayer book by an author named Frances Sheridan Goulart (looked up her bio but she doesn't seem to be anything more exotic than a writer, cook and gardener).

Anyway, the title is taken from the words of Mohandas Ghandi. Not a Catholic, but accepted by most as an all-around good guy. So if that's true - about God having no religion - and it sounds reasonable - what's all the fuss about? Shouldn't any path to God be OK?
