Let's not be under any impression that what we see on these threads is representative of all of Protestantism. As I know you are well aware there are many good and decent Protestants. Similarly I know full well there are those who present themselves as Catholics that fall well short of perfection.
However, the proof of anyone's Christianity is not found in their words, talk is cheap. As stated in the Confiteor it is to be found in their actions, what they have done and what they have failed to do. Simply look through the posting histories of all associated with these threads and see whose words and actions suggest love manifest in the fruits of grace. If anyone tries to tell you that they can achieve salvation without ever leaving the comfort of their den pray for them because they need it.
You may want to compare the words on this forum to words Jesus uses to those who don’t believe what He says.
