Kerygma

Kerygma (from the Greek word κήρυγμα kérugma) is a Greek word used in the New Testament for "preaching" (see Luke 4:18-19, Romans 10:14, Matthew 3:1). It is related to the Greek verb κηρύσσω kērússō, literally meaning "to cry or proclaim as a herald" and being used in the sense of "to proclaim, announce, preach". Merriam-Webster defines it as "the apostolic proclamation of salvation through Jesus Christ".
