Titus 1:15-16

New Revised Standard Version, Anglicised Catholic Edition

¹⁵ To the pure all things are pure, but to the corrupt and unbelieving nothing is pure. Their very minds and consciences are corrupted. ¹⁶ They profess to know God, but they deny him by their actions. They are detestable, disobedient, unfit for any good work.
