Titus 1:13-17

This testimony is true. For this reason reprimand them severely so that they may be sound in the faith,

not paying attention to Jewish myths and commandments of men who turn away from the truth.

To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure, but both their mind and their conscience are defiled.

They profess to know God, but by their deeds they deny Him, being detestable and disobedient and worthless for any good deed.
