Kerygma

"The Apostles Going Forth to Preach" (Très Riches Heures du Duc de Berry, c. 1412–16)

Kerygma (from Ancient Greek: κήρυγμα, kḗrygma) is a Greek word used in the New Testament for "proclamation" (see Luke 4:18-19, Romans 10:14, Gospel of 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". Amongst biblical scholars, the term has come to mean the core of the early church's teaching about Jesus.
