Titus 1:14-16

not giving heed to Jewish fables, and commandments of men, that turn from the truth. Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled. They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
