Titus 1:10-16 NIV
For there are many rebellious people, full of meaningless talk and deception, especially those of the circumcision group. They must be silenced, because they are disrupting whole households by teaching things they ought not to teach—and that for the sake of dishonest gain. One of Crete’s own prophets has said it: “Cretans are always liars, evil brutes, lazy gluttons.” This saying is true. Therefore rebuke them sharply, so that they will be sound in the faith and will pay no attention to Jewish myths or to the merely human commands of those who reject the truth. To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted. They claim to know God, but by their actions they deny him. They are detestable, disobedient and unfit for doing anything good.
