By "members" I meant "people claiming to be members of Christ". That is, people claiming to be saved.
I was not talking about "the wayward" as lapsing from church membership per se: I was speaking of "the wayward" as people claiming that they are members of the Body ---saved ---- and yet involved in ongoing, intentional, unrepented sin.
So I repeat: can a self-described "saved" person be saved without repentance from sin?
If they don't repent, they don't turn to Christ, hence are not saved.
Jesus said by their fruits you will know them.
Someone who claims to be saved and lives like he's not isn't.
