Unto the pure Namely, believers whose hearts are purified by faith, Acts 15:9; all things are pure All kinds of meats are lawful to be used; but unto them that are defiled Who are still under the guilt and power of sin; and unbelieving Destitute of true, saving faith, to purify them; nothing is pure Nothing they do, enjoy, or possess: they are still defiled with guilt, and are exposed to condemnation and wrath from God. The apostle joins defiled and unbelieving, to intimate that nothing can be clean without true faith. For even their mind Their understanding, whereby they should distinguish between what is lawful and what is unlawful, and their conscience, whereby they should judge of their own actions; is defiled Blinded, perverted, and polluted with past guilt and present depravity; and consequently so are they, and all they do. They profess that they know God And glory in their relation to him as his peculiar people, and boast of having the true knowledge of his will from the Mosaic revelation; see Romans 2:17; but in works they deny him Live in contradiction to the very law they profess to know, as if they were utterly ignorant of him and it; being abominable Worthy to be abhorred and avoided by all; and disobedient To the plainest dictates of duty to God and man; and unto Or, with respect to; every truly good work reprobate Αδοκιμοι, without discernment; neither judging truly, nor acting rightly: or disapproved and condemned, when brought to the standard of God's word, though almost among the first to condemn others.
