Practice makes perfect. I used to believe that, but many years ago when I took up golf, I discovered, as one of my friends told me, "Practice makes permanent." I spent untold numbers of hours trying to perfect my swing and achieve long, straight drives from the tee. To no avail. To my great embarrassment the ball would dribble off the tee or, if I did make good contact, it would sail far to the right or to the left. Rarely would it go far and straight. It was not too long before I gave up on golf and stayed with the sports I learned to play on my own.
There was a time when most Catholics would define themselves as "practicing Catholics." And I suppose that most of us thought that gradually by practicing our faith we would achieve, not quite perfection, but be good enough to qualify for a place in heaven where perfection would be our final outcome.
Today, however, a very large number of Catholics have given up.
