It is a real joy when you can find a teacher that is both anointed and educated....the primary example we have for this is the Apostle Paul....he was both.....
Regardless of whether they're anointed or not, formally or otherwise, some will disregard the message because they don't approve of the messenger. It may well be a perfectly valid message stated in honour but a person who is rife with the enemy's deception will shoot it down out of insecurity, possibly more so when it's come from the Lord.
