 The Ten Commandments, the Decalogue. And I encourage you to read it. A lot of people are intimidated by the Catechism. Don't be. Just because it can be kind of thick, especially if it's in a large print edition, you say, wow, my goodness, that's a great table, coffee table book. It's a great paperweight. But man, it seems too intimidating to read it. It's really not. The Catechism is actually beautifully done.
