I don’t think anyone intends to bash but to stand up for the truth, as we need to do, although some of us, me included, could have been more loving in the way we did it. Mea culpa!
What anyone who leaves the Catholic Church for a Protestant denomination or a non-Christian religion or atheism does is commit an act of formal heresy because he or she is denying one or more teachings of the Church in order to embrace whatever teaching they will accept of another body of believers not in full communion with the Catholic Church (putting it in my own poor words).
Now, we don’t know if the poster being discussed is culpable or not because we don’t know if she left with full knowledge, full understand, and full consent of her will. I assume from what she has told us that it was at least with full consent of her will, but I very much doubt it was with full knowledge and full understanding. All that would be for her confessor to determine, not us, anyway. But, we cannot rejoice that she has abandoned Christ’s one, holy, catholic and apostolic Church merely because she doesn’t want to believe some of the things the Church teaches. That is a tragedy not a good thing.
As for those who were brought up ECUSA and other Protestant denominations, they are material heretics, which is another whole ball of wax with another whole set of determinations as to whether or not they will be saved. Of course none of us knows if we will be saved (although we can have moral certainty of it), so we are not judging anyone’s salvation but merely saying that by abandoning the Church she has cut herself off from fully participating in the life of the Church. Instead of picking and choosing what she will practice and believe and what she won’t, she ought to have done what she recited every Sunday at Mass and embraced the full teaching of the Church, conforming herself to it instead of listening to other voices that obviously robbed her of her faith in the Church.
