Worse than ignorance
Spurious knowledge, or ‘knowledge falsely so called’ (1 Timothy 6:20), is that which a man possesses when he thinks he knows what he has never known. It is worse than complete ignorance, says St. John Chrysostom, in that its victim will not accept correction from any teacher because he thinks that this worst kind of ignorance is in fact something excellent. For this reason the fathers say that we ought to search the Scriptures assiduously, in humility and with the counsel of experienced men, learning not merely theoretically but by putting into practice what we read; and that we ought not to inquire at all into what is passed over in silence by Holy Scripture.
