An Interesting review on Amazon - worth a look. A one star rating review This encyclopedia is great if you are doing research on what Modernists Believe. It will help you to see how modernists twist the traditions and beliefs of the church. For example: 1. Regarding purgatory it says: it has been affirm by Trent and the popes...however it goes on to say, the teachings of the church on purgatory are limited and there is room for "theological reflections". This author certainly is not a friend Thomas Aquina's purgatory views. 2. It tries to minimize mortal sin, I say it almost define Mortal Sins as a state of mind. I don't regret buying this encyclopedia. It helps me see exactly how modernists twist catholic beliefs to suit their needs. To be FAIR In the cover of the book it says clearly what the book will attempt to do: "...It attempts to give a succinct and contemporary view of the beliefs,practices and history of this" (this means the church). This book should only be used by adults that cannot be indoctrinated. Certainly not for use by children that can easily believe what they are told.
