Titus 1:12-16

1:12 A certain one of them, in fact, one of their own prophets, said, “Cretans are always liars, evil beasts, lazy gluttons.” 1:13 Such testimony is true. For this reason rebuke them sharply that they may be healthy in the faith 1:14 and not pay attention to Jewish myths and commands of people who reject the truth. 1:15 All is pure to those who are pure. But to those who are corrupt and unbelieving, nothing is pure, but both their minds and consciences are corrupted. 1:16 They profess to know God but with their deeds they deny him, since they are detestable, disobedient, and unfit for any good deed.
