Repeated weekly experience. I would prefer not to derail the thread by focusing this. What do I need to learn in order to be a good Catholic?
Here are a few things I thought of off the top of my head.
Eventually, memorize the following prayers, in addition to those you already mentioned. I recommend memorizing them in this order:
The Act of Contrition
Hail Mary
Glory Be
Oh My Jesus
Hail, Holy Queen
The St. Michael Prayer
You don’t have to do them all tomorrow.
In fact, there is no requirement that you memorize any of them at all. But I wish somebody had told me to memorize these while I was in RCIA. You will find yourself in situations where they will be good to know off the top of your head.
Learn about what baptism is, what it does, and why we baptize infants.
Learn about what confirmation is and what it does. Same with confession.
Learn about the Church’s teachings on contraception, marriage, and human sexuality.
Learn how the Church views the Ten Commandments.
Learn about Purgatory.
Learn about scrupulosity.
Learn about justification.
Buy a Catholic calendar that has all of the holy days of obligation on it.
Plan on going to confession regularly. You don’t have to go to the same parish with the same priest every time.
When I say “learn about,” I don’t mean “become an expert.” I mean, “get a rudimentary understanding of this subject.”
I am assuming that you already have a grasp on the basics, such as why Christ came, who Christ is, the role of Christ’s mother, the Trinity, the Eucharist, cooperating with grace, heaven, hell, the resurrection. If not, then those things should be reviewed as well.
This is not a complete list, and I don’t know your background so I may have mentioned things you already know.
I suspect you are doing better than you imagine. Take care and keep us posted.
P.S. Remember that is is more about developing a love relationship with Jesus and his Church. Following the rules is supposed to be part of that, not separate from it.
