Titus 1:10-16 - Correct Whoever Teaches What Is Wrong
10 For there are many that spurn authority--idle, talkative and deceitful persons, who, for the most part, are adherents of the Circumcision. 11 You must stop the mouths of such men, for they overthrow the faith of whole families, teaching what they ought not, just for the sake of making money. 12 One of their own number--a Prophet who is a countryman of theirs--has said, "Cretans are always liars, dangerous animals, idle gluttons."
13 This testimony is true. Therefore sternly denounce them, that they may be robust in their faith, 14 and not give attention to Jewish legends and the maxims of men who turn their backs on the truth.
15 To the pure everything is pure; but to the polluted and unbelieving nothing is pure, but on the contrary their very minds and consciences are polluted. 16 They profess to know God; but in their actions they disown Him, and are detestable and disobedient men, and for any good work are utterly useless.
