This isn't even about "Feeneyism" per se. OP described people committing mortal sin. Yes, they would be lost if they died in that state. Yes, >90% of all the people in the world right now are likely not in a state of grace. That has absolutely nothing to do with Father Feeney. Nor does the fact that Father Feeney had a "narrow" view of EENS change the fact that these people are in a state of mortal sin. Stop blaming every darn thing in the world on Father Feeney.
OP and several other posters on this thread reveal once again that EENS-rejection comes from a place of emotion rather than from theology. Yes, it's very sad that fornicators go to hell (if they don't repent). But are we to doubt that now as well just because it's sad?
