I was never a protestant. My mother was Jewish and my father nothing.
I became Catholic in my 30s, due to the influence of a nun with whom I was doing volunteer work— she was very well educated, wore a habit, and lived her vows.
My many brothers and sisters have come into a large spectrum of beliefs, from Mormon, to Presbyterian, to Evangelical, to nothing, to Jewish. Along the way, I fell in love with, of all things, country gospel music...even though my husband was a classically educated musician.
I know lots of protestants, and have shared their worship services. None of them act like the protestants here.
I learned to call Jesus Christ my Lord and Savior from the nun who basically taught me, not the Catechism, but how she lived HER faith. She’s the one who got me into RCIA, and I have loved the Church ever since.
PS, I don’t see many apparent protestants using Christ’s Holy Name, either. I suspect it’s not a habit with most people, but my salvation is my salvation, and I do what I do.
That understandable...However, most Catholics I know act like the Catholics here...
