Titus 1:15

“Unto the pure all things are pure, etc.] The apostle having made mention of Jewish fables, and the traditions of the elders, takes notice of some darling notions, that these judaizing Christians had imbibed or retained; that there were some things, which being touched, or handled, or tasted, occasioned uncleanness, and which the apostle denies to them that are “pure”; by whom are meant, not such who are so in their own eyes, who yet may not be cleansed from their filthiness; nor do any become pure through ceremonial, moral, or evangelical performances, done by them; they are only pure, who are justified from all sin by Christ's righteousness, and are clean through the word or sentence of…”

“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" (Tit 1:14), which forbade certain things as if impure intrinsically. "To the pure" inwardly, that is, those purified in heart by faith (Act 15:9; Rom 14:20; Ti1 4:3), all outward things are pure; all are open to, their use. Sin alone touches and defiles the soul (Mat 23:26; Luk 11:41). nothing pure--either within or without (Rom 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…”

“Unto the pure all things are pure - See the notes at Romans 14:14, Romans 14:20. There is probably an allusion here to the distinctions made in respect to meats and drinks among the Jews. Some articles of food were regarded as “clean,” or allowed to be eaten, and some as “unclean,” or forbidden. Paul says that those distinctions ceased under the Christian dispensation, and that to those who had a conscience not easily troubled by nice and delicate questions about ceremonial observances, all kinds of food might be regarded as lawful and proper; compare the notes at 1 Timothy 4:4-5. If a man habitually maintains a good conscience in the sight of God, it will be accepted of him whether he do or…”

“To the pure - Those whose hearts are purified by faith this we allow. All things are pure - All kinds of meat; the Mosaic distinction between clean and unclean meats being now taken away. But to the defiled and unbelieving nothing is pure - The apostle joins defiled and unbelieving, to intimate that nothing can be clean without a true faith: for both the understanding and conscience, those leading powers of the soul, are polluted; consequently, so is the man and all he does. Next: Titus Chapter 2”

“1:15-16 These two verses comment on the people of 1:14 and their commands, while transitioning to a discussion of wholesome teaching (2:1–3:11). 1:15 Cp. 1 Tim 4:3-5.”
