The bible tells us we can have the mind of Christ, whatever that means to you. Scripture is truth. The magesterium is not the only means to interpreting scripture. Much of it is very simple and clear. You don’t have to be a dummy to interpret most of it. Yes, there are mysteries, allegories, parables and the like but the simple gospel is just that: simple.
In fact, it can “make the simple wise”
>>Much of it is very simple and clear<<
Not to me! I’ve been led astray before.
