Thematic Bible: Whose conscience is defiled

For there are many rebellious people, especially among the circumcision [i.e., the Jews], whose talk is useless and who deceive people. They must be silenced [because] they are upsetting entire families by teaching things they should not be for the shameful purpose of making money. Even one of their own prophets said, "The people of Crete are always liars, vicious beasts and lazy gluttons." read more.
[And] this testimony is true. [So], for this reason you should rebuke them severely, so that they will be sound in the faith, instead of paying attention to Jewish myths and commandments of men who reject the truth. Everything is pure [i.e., ceremonially acceptable] to the person who is pure [i.e., who has been cleansed by the blood of Christ], but to those who are [spiritually] corrupt, and do not believe [in Christ], nothing is pure, but both their minds and consciences are corrupted. [Note: This statement was intended to remove the physical restrictions imposed by the law of Moses].
