What about the sects that are "works based"? Mormonism teaches that "exaltation" is ONLY reached through baptism and confirmation in the mormon church PLUS the "ticket into Heaven" is an actual paper or digital "ticket" allowing the ticket holder to enter a mormon temple and take part in certain rituals.
So, as a consequence millions of us are considered by the mormon church to be "heretics" because "our work" isn't done.
We are therefore sent to the back of the "celestial" bus while the "elites" enter Heaven and are allowed to associate with God.
So many Christians will enter a thread on mormonism and make the claim that you have just made in ignorance of the exclusivity of mormonism.
(Side note: There is even, in mormon doctrine, a ritual that guarantees the living mormon that their "calling and election" place in Heaven is assured...
Works have their place. Faith is what gets you there, works proves your faith. Paul wrote explicitly and plainly about the relationship between works and faith. One should strive for a sinless life ("I die daily"). That is works. But it doesn't save. Faith in Jesus alone saves. I abhor the beliefs of Mormons. I don't abhor Mormons though.
