Jamieson, Fausset, and Brown
all things—external, "are pure" in themselves; the distinction of pure and impure is not in the things, but in the disposition of him who uses them; in opposition to "the commandments of men" (Titus 1:14), which forbade certain things as if impure intrinsically. "To the pure" inwardly, that is, those purified in heart by faith (Acts 15:9; Romans 14:20; I Timothy 4:3), all outward things are pure; all are open to, their use. Sin alone touches and defiles the soul (Matthew 23:26; Luke 11:41).
nothing pure—either within or without (Romans 14:23).
mind—their mental sense and intelligence.
conscience—their moral consciousness of the conformity or discrepancy between their motives and acts on the one hand, and God's law on the other. A conscience and a mind defiled are represented as the source of the errors opposed in the Pastoral Epistles (I Timothy 1:19; I Timothy 3:9; I Timothy 6:5).
