The Old Guide
At the adoration chapel that I attend as often as I can, there is a small library of books (most of them quite questionable) that you take into the chapel with you and read as spiritual meditation in front of Our Lord.
I have taken to bringing in with me the Baltimore Catechism that I read a bit after all of my prayers and devotions. Though I had heard about the Baltimore Catechism, I never actually read it nor was it ever presented to me as a guide for my Catholic Faith. A shame but not surprising.
As I began to read through the Catechism, it was amazing to me to read things I had never heard before from anyone and said in such a confident way. One example:
the job of a Catholic is to know, love, and serve God.
That's it. Nothing else. Simply said and simple to understand.
Ever hear that in a homily? Or in RCIA or Sunday School?
I strongly suggest that everyone find or buy a Baltimore Catechism and just start with page one. It's meant to be read from front to back straight through. And prepare yourself -- you might come across things in the Faith that you have never of before and didn't know. But keep in mind one thing that many Catholics seem to be confused about:
NOTHING IN THE BALTIMORE CATECHISM HAS BEEN ABROGATED.
