In 2005. Pope Benedict XVI published a Compendium of the Catechism, which is in question and answer format. This is a great source if you have questions about the faith or you have a friend or family member with questions. It is a good tool for sharing your faith and a source for you to refresh your knowledge of the Catholic Faith.
Here is a link to the document on the Vatican website. It is a long document, so if you plan to print it, be aware that it is hundreds of pages. We encourage you to share this link with your friends too
May the Lord bless you with an increase of knowledge of the Catholic faith.
