Titus 1:10-16 - Correct Whoever Teaches What Is Wrong
10 For there are many unruly men, vain-talkers and deceivers, especially those of the circumcision, 11 whom it is needful to reduce to silence: who, indeed, are overthrowing whole houses, teaching what they ought not, for the sake of base gain. 12 One of themselves, a prophet of their own, said, "Cretans are always false, evil beasts, idle gluttons."
13 This testimony is true. For which cause, reprove them sharply, that they may be sound in the faith; 14 not giving heed to Jewish fables, and commandments of men who turn away from the truth.
15 To the pure all things are pure; but to the defiled and unbelieving nothing is pure; but both their mind and their conscience have become defiled. 16 They profess to know God; but by their works they deny Him; being abominable, and disobedient, and for every good work worthless.
