“In other words, while they attended Protestant churches, they were not Christians”
OK. Knew that one was coming. Try emailing Scott Hahn, Marcus Grodi, Tim Staples, Jimmy Aiken, and the vast majority of other Catholic apologists and tell them they were not Christian. Make sure you let us know what they say in their replies. LOL.
Already read Hahn's stuff...He never had a relationship with Jesus til he saw him sitting in a monstrance in one of your churches...
I read Staples stuff...He never encountered Jesus until he ate a Catholic cracker...He always knew something was missing...And that was Jesus...
Without Jesus, you ain't no Christian no matter how pious you look...
