Examine the Teacher’s Teaching

If anyone teaches otherwise and does not agree to the sound instruction of our Lord Jesus Christ and to godly teaching 4 they are conceited and understand nothing. They have an unhealthy interest in controversies and quarrels about words that result in envy, strife, malicious talk, evil suspicions 5 and constant friction between people of corrupt mind, who have been robbed of the truth and who think that godliness is a means to financial gain.          1 Timothy 6:3-5

Examine the Teacher Himself

They are conceited and understand nothing. They have an unhealthy interest in controversies and quarrels about words that result in envy, strife, malicious talk, evil suspicions 5 and constant friction between people of corrupt mind, who have been robbed of the truth and who think that godliness is a means to financial gain.          1 Timothy 6:4-5

But now you must rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips.  Colossians 3:8

He who conceals his hatred has lying lips, and whoever spreads slander is a fool.  Proverbs 10:18

Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. 29 They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips,30 slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; 31 they have no understanding, no fidelity, no love, no mercy. 32 Although they know God’s righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them.        Romans 1:28-32
