Calvinists definitely believe ethical improvement is possible
I’m a stranger to theology so maybe I’m misunderstanding, but it sounds like Calvin thought people had free will, but other “Calvinists” thought one’s moral status was predestined by God, prohibiting ethical improvement. (I assume John Calvin isn’t going to exercise a Dennett/Conway Perspective Flip Get-Out-Clause, because if he does, the universe is trolling me).
(Aside: I sometimes think atheists with Judeo-Christian heritage risk losing the grace and keeping the damnation)
[F/X: penny drops]. Thank you.
