Catechesis – ‘religious instruction to a person in preparation for Christian baptism or confirmation, typically using a catechism.’
Even if you’re already baptized and/or confirmed, we all need to practice our ABCs.
Why don’t we all do it together?
I would encourage you to make a practice of studying this catechism regularly.
For advanced catechesis, see here. I have a few copies in my office and would be delighted to start a discussion group.
