What I find very interesting is most people coming into the Catholic Church are men and women that were well aware of what they were leaving behind. (Scott Hahn, Kimberly Hahn, Tim Staples, Alex Jones, etc.). But the opposite is almost rarely the case. Most Catholics that leave the Church had an immature understanding to begin with. This is speaking in general terms. Obviously someone can point to Luther to show otherwise but there aren’t many Luther’s out there. Even then Luther didn’t fully grasp the Church’s position on Grace and so on. His writings seem to show that he first came to a good understanding of salvation in his latter years and his rejection of the Church began.
