Pope Benedict XVI has suggested that if we read a little of the The Second Edition of the Catechism of the Catholic Church daily, we can read it in its entirety in one year.
The Second Edition of the Catechism of the Catholic Church is the green book pictured above. The Catechism has also been adapted into two easier to understand versions. The Catechism for Adults is the red book pictured above, perfect for adults who want to deepen their faith. The Youth Catechism, or Youcat, is the yellow book pictured above.
The Second Edition of the Catechism of the Catholic Church is available to read online, by clicking the green book above. The Catechism for Adults is available for purchase online through USCCB's Web site, by clicking the red book above. The Youcat is available for purchase as an E-book, or a regular hard copy by clicking the yellow book above.
For further study, the public is also encouraged to become familiar with the Code of Canon Law.
