Why the disagreement
This is at least three separate disagreements, not one. Reformed and Southern Baptist land on "no" because they define saving faith by its outcome — if someone falls away, the faith wasn't real to begin with, which makes the position unfalsifiable by design. Catholic, Lutheran, Wesleyan, Pentecostal, and Adventist land on "yes" by locating the loss at different points — a single mortal sin, ongoing unbelief, sustained rejection, a broken relationship, a final judgment — but they share the premise the Reformed position denies: that real faith can still fail. The Orthodox families reject the frame underneath both sides, treating salvation as a lifelong process rather than a status with a beginning that can be dated. LDS and Jehovah's Witnesses aren't arguing inside this frame at all — they're using different categories entirely.
None of this resolves by more argument. The Reformed/Wesleyan split depends on an unfalsifiable claim about what happened at the moment of "true" conversion. The Orthodox split depends on whether salvation is an event or a process before the question is even asked.
Solving the disagreement
Two different things would have to happen for this to resolve, and neither is close to available. The Reformed/Wesleyan fork turns on whether a specific person's faith, at the moment they first believed, was ever "real" in the sense that guarantees perseverance. That's not a claim either side can check — the Reformed position defines real faith partly by its outcome, so any case of falling away gets read after the fact as proof the faith was never real to begin with. There's no independent test that could run before the outcome is known, which means no future evidence resolves it; the position is constructed so that it can't be falsified.
The Orthodox fork turns on something different: whether salvation is the kind of thing that has a datable beginning at all, or is instead a lifelong process without that structure. That's a metaphysical premise that sits underneath the yes/no debate, not a conclusion reachable from it — two people who agree on every relevant Bible verse can still disagree here, because the disagreement is about what kind of thing salvation is before either of them opens a text.
