1. The Hiding Place by Corrie Ten Boom.
Christianity writ large. You want to understand Christian spirituality, this is your book.
2. Handbook of Christian Apologetics by Kreeft & Tacelli.
You can’t learn everything about the faith by reading apologetics, but you can sure learn a lot. If you actually want to know what folks believe and why they believe it, a book of this nature is as useful as anything, and usually more fun than a straight reference book.
3. The book of your choice. A few that come to mind, pick any one, or a different one:
- Happy Catholic by Julie Davis.
- Who is Jesus Christ? by Eric Sammons.
- Catholicism Pure & Simple by Fr. Dwight Longenecker.
- Why Enough is Never Enough by Gregory S. Jeffry.
- Anything by Chesterton or Knox or Mark Shea.
- Theology for Beginners by Frank Sheed.
- Something by Tolkein, or one of the Narnia books from CS Lewis.
- Something written by a pope.
- Something written by a saint.
- A Bible or catechism, hey, why not? Maybe it’s against the rules, I didn’t read them all.
- Some other book.
You really don’t need three books. But you get three, so you might as well pick something you like.
