Novus ordo ignores the necessity of sanctifying grace as does a Feenyite sedevacantist.
A non-Feeneyite sede understands that all who die in the state of Sanctifying grace, die a Catholic and are saved, many through the mercy of God.
Myrna, this is inaccurate. You can die in state of sanctifying grace without being member of the Church. There are not "hidden membership" either.
Now, if you meant "all who die in the state of Sanctifying grace die
inside the Catholic Church", then it would be correct.
