The Catechism - basically, the "operating instructions" for being a Catholic - isn't just for Catechism class prior to First Communion and Confirmation. It's an amazing collection of Church teachings and rules that cover everything from the basics, like honoring God, to more unusual subjects such as paying just wages and respecting animals. An understanding of the Catechism is key to the daily life of Catholics, and an appreciation of what Catholics believe. In Spanish.
