As if the two are mutually exclusive? Is that your point? If it is, and your comment leads to that conclusion, then you have a problem with St Paul, who told Timothy to take what he (Paul) and taught him (Timothy) and deliver it to "faithful men."
He did not tell Timothy to read the Bible to them.
How do you know what Paul and Timothy said?
My point is that they CAN be exclusive and that any a priori claim of equality to the wisdom of God can and should be open to critical examination. There are a lot of materials written by "spiritual masters" today. Christians are directed IMHO to weigh these writings to see if they really contain the wisdom of God or the 'wisdom of man'. I think you and I could come up with many such writings where the wisdom of these "spiritual masters" is seriously at odds with scriptural teachings on the subject.

One could try to make that comparison - but it is a flawed dilemma because Paul's teachings to Timothy included those things later consolidated into the NT as scripture. Timothy had the benefit of learning from a source, a situation that we are unable to repeat except through study of the NT writings. So if one has a problem with Paul, then one would likely have a problem with Paul's writings. I cannot see that Paul would have taught Timothy anything different than what was canonized. The writings of these other "spiritual masters" do not even approach those of Paul and the others in the NT.
