Query: Catechism of the Catholic Church

This is the latest official version of the Catholic Catechism (as of Jan 08). This is set up in an outlined version, although it is very thorough. Footnotes are employed to verify the information, which are often biblically based.A companion reference of some sort is helpful in explaining this information. This could be another learned person of the Catholic faith, or one of several publications available. Even though the book can be difficult reading, the information is the bottom line of what Catholics believe.
