I am a recovering Protestant, and I have been sober for 15 years. That twist on a phrase used by Alcoholics Anonymous is a helpful way of pointing us to the fact that sometimes people who convert to the Catholic faith do not always root out certain non-catholic habits. There is a Catholic manner of obedience; there is a Catholic manner of morality; there is a Catholic manner of Bible study; there is a Catholic manner of worship; and there is a Catholic manner of family order (and, honestly I could come up with a hundred other points in this list!).
This is to say that not everyone realizes it when he still behaves as a protestant after he has converted and been received into the Church. I recall once in my first year after I became Catholic catching myself a few times thinking of certain procedural things in the way that I used to do them as an Anglican (and they were so different from the Catholic way that I feel embarrassed to mention it). I am sure that others have experienced the same kind of things.
The faith journey that each of us is on, is to move away from the world and toward Christ. That means that we each have things that we need to overcome. If those things seem "kinda like" Catholic things it can be hard to make that distinction. If someone comes to you and says "that isn't the Catholic way", they might not be correct, but they also might be correct. Do not presume that you are right and the other person is wrong. Examine yourself; look into the details, and be thankful that God is willing to help you be more fully Catholic in all you do.
