At what point does False Doctrine effect salvation?

[stmatthew]

I seem to be full of questions lately.


It is commonly stated that some doctrines are "salvational" or "heaven or hell", while others have no bearing on our salvations. This would mean that some doctrines are not important in the scope of salvation, right?

So my question is, Can one continue to walk in a false doctrine, rejecting the true doctrine, and continue to be saved? Would not the rejection of a true doctrine over a false doctrine constitute that one is rejecting being led by the Spirit, thus constituting one is now being led by another force?
