Ok. I say this in all charity and sincerity:
If you want to be a good Catholic, go to Mass regularly, receive Reconciliation regularly, receive Eucharist while in a state of grace, read the bible, got to Adoration, study the important writers in the Church, and develop a relationship with a great catechist, even your priest or a religious in the parish.
There’s not a thing you can buy, or card you can get punched, or magic want that you can wave and blamm-o! You’re a great Catholic.
Being a great Catholic Christian takes more of an investment than simply signing up for one set of classes. You’re a Catholic by virtue of your Baptism and your Confirmation.
If you want to get more in tune with the Lord…draw near to Him.
Pray. Study. Meditate.
Be joyful. Be humble. Do works of mercy.
It’s never too late to start.
