This is a truly excellent book. If you are interested in the faith, this treasury of information will be a great help! If you are a Catholic - then why havn't you got one?! Arranged in the old style question and answer format, it provides the same information as the larger, more expensive, 'Catechism of the Catholic Church', is easier to understand, and the economical price makes it more attractive! It includes Pope Benedict's Motu Proprio, and his original introduction, as well as some beautiful illustrations and descriptions to match.
