I already addressed the op. If the op intended to pit spiritual truth against bad doctrine it should have said so. But it didn't.
And I would add that the OP contrasts spiritual truth with simple doctrine explicitly.
Scripture, however, seems to indicate otherwise - that the truth of Scripture and the work of the Spirit leads us to spiritual knowledge which is something other than, deeper than, and even more important than simple biblical doctrine.
I do think it could have been worded a little better but I think there are some truths to what it seeks to convey.
Whether they are spiritual truths or not, well, we'll never know, because no one seems to be interested in threshing it out.
God bless.
