Q: While this book is very good on providing scripture quotations, the commentary is dated and extremely biased. If this book were to be shared with people of non-Mormon faiths, they would become very defensive and rightly so. The author's invective toward the Catholic faith is appaling. Many Mission Presidents do not recommend this book. It could be dangerous in the hands of the untrained.
A:
Negative
