I would like to start a discussion regarding doctrines that imply or explicitly say that the bible (and agreeing with a particular interpretation of it) is necessary for salvation.
It is an open discussion so long as it remains within that general area.
I'm going to say something that will be very controversial because it totters awfully close to violating TOS here.
I'll answer with a question: How much of God's word in the Bible does one have to disbelieve before one believes in a false god, and thus is not truly saved?
I offer up as an example someone who holds to a strictly materialistic, naturalistic science-only view of creation. I'm talking about hard-core evolutionists who also
profess to be Christians.
A favorite Bible teacher used to say, "If you have a problem with the first seven words (in Hebrew) in the Bible, then you've got a whole lot more problem than just not believing God created everything."
That's because even Christ quotes from Genesis, which means He takes it literally. But these evolutionists actually carry water for the atheists, being almost indistinguishable from them in dialogue. Is that Christ-like? Is that being indwelt with the Holy Spirit?
And then, here on CF I've seen some absolutely wacky Scripture interpretations, particularly regarding the rapture, end times and the tribulation that it makes me wonder if someone actually believes in the true God of the Bible.
So, yes, I believe there is a point where "agreeing with a particular interpretation" becomes a question of salvation, when that interpretation strays so far from God's word. At what point that is ... I don't know. Only God knows.
