Titus 1:10-16 - Correct Whoever Teaches What Is Wrong
10 For there are many unruly and vain talkers and deceivers, especially those of the circumcision, 11 whose mouths must be stopped: these subvert whole houses by teaching, for the sake of base gain, things which they ought not to teach. 12 One of themselves, a prophet of their own, has said: The Cretans are always liars, evil wild beasts, lazy gluttons.
13 This testimony is true; wherefore rebuke them severely, that they may be sound in the faith, 14 and not give heed to Jewish fables, and commandments of men that turn away from the truth.
15 To the pure, all things are pure: but to the denied and unbelieving, nothing is pure; but their mind and their conscience are denied. 16 They profess that they know God, but in their works they deny him, being detestable and disobedient, and, as it respects every good work, rejected.
