Titus 1:10-16 - Correct Whoever Teaches What Is Wrong
10 For there are many disorderly persons vainly talkative, and under a spirit of delusion, especially some of the circumcised; 11 whose mouths ought to be muzzled, who pervert whole families, teaching things which they ought not, for the sake of base gain. 12 One of them, a poet of their own nation, hath said, The Cretans are always liars, wicked beasts, slothful gluttons.
13 This testimony is true. For which cause rebuke them with severity, that they may be sound in the faith; 14 not attending to Jewish fables, and injunctions of men, who have turned away from the truth.
15 All things indeed are clean to the clean: but to the defiled and to the unbelievers there is nothing clean; but their very mind and conscience are defiled. 16 They profess to know God; but in works deny him, being abominable and disobedient, and unto every good work reprobate.
