Leo the Great, on Titus 1:16

“They profess that they know God: but in their works they deny him; being abominable, and incredulous, and to every good work reprobate.”

“Our peace also has its dangers, dearly beloved. In vain do people feel secure as a result of freedom for their faith if they do not resist the desires of vice. By the quality of works is the human heart made known, and outward actions disclose the beauty of souls. There are some, as the apostle says, who "profess to know God but deny him through their deeds." Truly the guilt of denial is incurred when the ears have heard what is good but the conscience does not hold on to it. The frailty of the human condition easily slides into sin.”
