The Catholic Faith is a habit of life. If you cease to practice the Catholic Faith, you will cease to be Catholic. It's simple. How can you stay Catholic without practicing your Faith for decades?
Home-Aloneism proponents such as Fr. Joseph Pfeiffer LOVE to bring up and promote the "Japanese Hidden Christians". But far from being a good model for Traditional Catholics, these Japanese Christians were in VERY sad shape. They kept a faint memory of a couple basic dogmas (priestly celibacy, etc.) and not much more. I shudder to think how many of them lost their souls. The Hidden Christians are the "patron saint" of Home Aloners and Home Aloneism-promoters.
I have no respect OR devotion to these so-called "hidden Christians". Why would I? They weren't saints, they might have all gone to hell for all we know. We should NOT base our current actions on what these particular Japanese did, nor follow their path.
They used a Buddhist goddess statue, but secretly calling it Mary. But after centuries of using a Buddhist goddess statue, guess what happened? Many of them lost the Faith. THE FAITH IS A HABIT OF LIFE.
"Catholic is as Catholic does."
