Not surprising. Protestants pretty much just have the Bible.
Catholics believe they have the sacramental life, the Church, Holy Tradition, etc. in addition to scripture.
I’m a protestant convert to the Catholic Church. The very idea of “church” is quite different.
And ALL Baptized Catholics are “born again”. We just don’t call it that. All the sins are washed away with the Sacrament of Baptism and the person becomes a new person in the eyes of God.
