The term syneidēsis, “conscience,” appears more than twenty times in the New Testament, mostly in First Corinthians, but also in other Pauline epistles including Romans, Second Corinthians, First and Second Timothy, and Titus. Although Paul brought syneidēsis into the Christian lexicon, Luke also used it in his Acts, as did Peter and the writer of Hebrews. There are three instances in the wisdom literature of the Septuagint, translating the original Hebrew עדמ) mada’) from the root עדי (yod-daleth-ayin), “knowledge,” and one use of the root בל) lamedh-bet), “inner man, heart, mind, will.”
