"Nothing is more potent than the conscience: letters inscribed on it are indelible. I mean, even if everyone mounted a case to his or her conscience supported by favorable evidence, the conscience itself cannot tolerate the wickedness of falsehood. It is pricked and goaded and delivers its verdict incorruptibly. He says this here, too: the facts accuse you, and the conscience joins in testimony against you. He reminds them also of the groves, the altars, and what was done on them, and th threatens to give to the enemy all the wealth along with the idols."
-Theodoret of Cyr, On Jeremiah 4.
