See, that's an example of what goes wrong on the RF. I don't see that BB said that doctrine doesn't matter. And it's not pure evil (or of the devil) to think that. It's really rather realistic and his point is well made.
If our salvation depended on 100% correct doctrine, nobody would make it. NOBODY can claim to have 100% correct doctrine, because we are fallible, limited humans trying to understand the infinite mind of God with our puny human minds.
It ain't happening.
That said, there are those of us who don't believe that correct doctrine gets one into heaven.
Christianity is about a relationship with God, not getting our facts about Him correct.
I kind of doubt that many of the people, like the thief on the cross, had their doctrine down pat when they encountered Jesus and yet Jesus still told them they were saved (today you will be with me in paradise).
THIS sentence probably gave him that impression: Those things don't really matter though.
Doctrine is essential in order to evangelize, as we are commanded to do.
That those who have some uncertainty (large or small) about doctrine can obtain the promises of Christ is a given as God’s mercy is boundless.
I have not even hinted that one cannot know God in some beneficial way unless one knows everything about God - yet that is what you have concluded.
None of this supports BB’s preposterous claim that (paraphrased)
“we should not worry what falsehoods (erroneous doctrine) or truths (true doctrine) about God are being preached, because we just have to know God”.
What drivel it is to undermine the utter necessity of solid bedrock Gospel truth.
That God can work with us regardless of how little we know about Him is a wonderful thing, but how evil it is to encourage people to take so lightly the obligation we have to know as best as we can (which demands we seek truthful doctrine - not just any old doctrine).
We are invited to run a race - and running a race requires real effort, not a shoulder shrugging “whatever”.
