Excommunicate.
Not that her bishop will have the courage to do so, but that’s what’s needed.
Melinda, honey, pick one half of that sentence (probably the second half). You can't have both.
>>Excommunicate<<
No need. She has excommunicated herself. By going against Church Doctrine, she has excluded herself. Whether silently in hear heart or publicly on a megaphone, the sin is complete.
The fact she doesn’t recognize the sin, reject the sin, atone for it and ask for forgiveness compounds the sin.
I do not personally call her a sinner (although we all are). Church Doctrine is 100% clear, though.
