You absolutely did reference church membership.
Can a person gain salvation if they do not repent of their sins?
Only if they turn TO Christ instead of simply feeling sorry for their sin.
People can be sorry for their sin cause of the consequences of it, without having a desire to follow Christ.
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?
