This book is an excellent resource for any Catholic looking to expand their knowledge about the Catholic Church. It is very concise and very complete and offers a wide array of topics. Everything from the Early Christian Church, through information on the different councils, to different religious movements, and the lives of the popes and saints can be found. Also included are some excellent photographs that span the history and culture of the Church. There are a few entries that only provided basic information, but other than that, it is intended as a general overview rather than a profound work. Every eager Catholic, young or old alike, should and must have a copy!
